Content: Havana, Cuba.- Cubans are entering the final days of July with a forecast of high temperatures, accompanied by little rain throughout the national territory.

In recent days, the heat punished the inhabitants of the Caribbean island, where through the Institute of Meteorology it was learned that in 38 of the 68 stations subordinate to the scientific entity, temperatures above 34 Celsius degrees were reported.

Meanwhile, the nightly broadcast of the National Television Newscast specified that in the eastern territory of Granma 39°C were registered on Saturday.

Behind it, the most overwhelmed towns were Colón in the western province of Matanzas with 37.2 °C; and Bainoa, in the also western province of Mayabeque, with 36.5 °C; while in the capital the thermometers marked 36 °C.

Days prior to the establishment of these temperature records for the current month, the Institute of Meteorology warned about the arrival of a cloud of dust from the Sahara on the island.

The experts explained that this phenomenon would cause a new decrease in rainfall and would maintain the feeling of great heat.

These clouds contain iron, silica, fungi, bacteria, viruses, various pathogenic mites, among other elements. They can cause acute respiratory diseases, allergies and skin problems.

Dust from the Sahara affects coral reefs, and fruit, rice, sugar cane, bean and other crops. It is caused by storms that occurred in the Sahara desert, coming out of the African continent.

It moves over the freshest and most humid marine air, and joining the flow of the trade winds, it quickly reaches the Atlantic Ocean, the Caribbean Sea, and the Gulf of Mexico.

A massive dust storm from the Sahara Desert is expected to shroud the country, with experts warning citizens, especially those with respiratory disorders, to take precautions.

Professor Dr. Doğan Yaşar, a climate scientist, cautioned that a period of intense dust transport will begin on March 25.

"Red-colored desert dust laden with iron particles will arrive in large quantities," he explained.

"While this dust fertilizes the soil and benefits agriculture, it can also trigger allergy symptoms like dry cough and sneezing, especially for people with asthma or other lung conditions,” he said.

Yaşar emphasized the importance of wearing masks during this period. "People with lung diseases should wear a particle-retaining mask for three weeks, if possible," he advised. "Regular masks can offer some protection as well."

"A single pine tree produces 12 billion pollen. Thus, during this period, pollen multiplies very intensively in the air. When we inhale this, we experience discomfort. It is especially dangerous for people with lung diseases such as asthma," he added.

The dust storm is a natural phenomenon that occurs annually, transporting around two billion tons of dust from the Sahara to various parts of the world. The professor highlighted the ecological benefits of this dust, which acts as a natural fertilizer. However, he cautions that the concentrated dust can irritate airways and exacerbate allergies.

While the dust storm may cause temporary inconveniences, Yaşar reassured citizens that there's no need for alarm.

"The dust benefits agriculture, but it's important to be aware of the potential health risks, especially for those with respiratory problems," he concluded.

Content: Motorists are being warned of a potential threat to vehicles as weather maps indicate that a sizzling 'Saharan Plume' is approaching. The UK has so far experienced a week of wet and windy conditions, but hope is in sight for those seeking sunnier spells, as the temperatures are forecast to rise in the coming days.

Despite a week plagued by unpredictable weather, characterised by muggy temperatures and frequent rainfall, next week's forecasts hint at an upturn. From Sunday May 19 to Tuesday May 21, it's predicted we'll see a return of balmy temperatures and plenty of sunshine, making way for a potentially splendid half term break.

Predictions suggest the best of the weather will shine on the Midlands, Northeast England and Yorkshire, where certain regions are anticipated to bask in highs of around 23C.

Things are set to heat up even further come May 26, with London, the southeast and the south coast potentially seeing mercury levels touch a sweltering 24C. Meanwhile, the rest of the country is expected to stay comfortably above 20C.

Netweather reports that most of England can look forward to temperatures hovering between 22C and 24C. While a bit cooler, Wales will still have some spots surpassing 20C, with Northern Ireland showing a similar trend, reports the Mirror.

Adding their input, the Met Office has issued its own forecast for the upcoming week. Their prognosis for May 19 to May 28 is characterised as "changeable", with temperatures predicted to be "generally around or just above average."

The current forecast indicates: "Temperatures will be generally around or just a little above average. With winds tending to be light, it will feel warm in sunnier areas. As we head further into the following week, confidence lowers into the following week. On balance, a continuation of the showers in the south seems most likely, with the north continuing to see the best of any drier weather. Temperatures will probably remain a little above average."

There's growing speculation about another Saharan plume potentially warming up the UK soon. While the prospect of warmer weather might be welcome, it's important to note that such conditions can also pose risks to both people and vehicles.

One significant hazard associated with a Saharan plume is the dust it carries, which recently wreaked havoc across mainland Europe last month. This natural occurrence enchanted many with its hazy skies and vibrant sunsets, yet it also escalated air pollution levels, surpassing some of the European Union's safety thresholds in various regions, including popular vacation destination Spain.

In southern and eastern parts of the country, residents experienced air quality that was four times over the healthy limit for PM10 particle contamination, posing a particular threat to individuals with respiratory conditions like asthma.

The Saharan dust also poses a risk to vehicles, as the thin layer of dust that typically settles on cars after desert weather can scratch paintwork and windows if not properly removed. To safely clean off the dust without causing damage, motorists are advised not to rub or wipe the dust away, but to thoroughly rinse their vehicle first, ideally using a pre-wash, followed by a snow foam soak and a thorough rinse.

Saharan dust storms can cause allergy-related health issues in citizens due to the invisible allergens and potential pathogens they carry.

Many blame pollen when the allergy season begins, but there are “invisible travelers ” coming from the Sahara and Sahel region, who may be the cause of this allergy.
The huge dust plumes, which originate thousands of miles away in sub-Saharan Africa, travel by dust storms around the world every summer, carrying a mix of pollutants and potential pathogens across continents.
Dr. Shankar Chilam, a professor at Texas A & M University, led the task of understanding the biological movers within dust storms.
He and his team are working to identify microbes, specifically bacteria and fungi, that migrate with dust and explore their potential impact on human health.
Dr. Chillam ’ s research uniquely addresses how desert dust storms introduced these microbes into North America.
Dr Chillam and his team analysed samples of desert dust that arrived in Houston in 2018, measuring minerals, bacteria and fungi to check for any links.
Surprisingly, their findings revealed strong links between microbial biodiversity and specific elements, especially calcium.
While these elements occur naturally in the Sahara Desert, they are also found in local North American environments.
Identifying the exact source and payload of the dust remains a challenge that scientists continue to face.
Perhaps the most surprising discovery is that even seemingly lifeless dust clouds are full of biological activity.
High-tech DNA analysis allowed the team to create a reservoir of bacteria and fungi, even if the microbes themselves were not active.
Surprisingly, they found traces of several pathogens known to cause disease in humans, according to the World Health Organization.
Dr Daniel Spalink, an assistant professor at Texas A & M University, warns: “This doesn ’ t tell us whether they will be able to infect us and make us sick, but at least the DNA of many pathogenic bacteria and fungi has been identified in African dust. ”
Climate change is changing weather patterns globally.
This shift affects the behavior of dust storms, leading to differences in their frequency and severity.
The dust storm in the Sahara travels far beyond the borders of North America, affecting global ecosystems in profound ways.
The dust, which originates from the vast Sahara desert, is released on transcontinental journeys that affect climate, ocean biology and ecosystems far from its source.
As it travels across oceans and continents, desert dust reflects sunlight back into space, cooling the Earth ’ s surface.
This natural phenomenon acts as a counterbalance to the greenhouse effects of greenhouse gases, illustrating how desert dust can affect global temperatures.
Dust also carries microorganisms and nutrients, such as phosphorus, which fertilises remote ecosystems, from the Amazon rainforest to the Caribbean Sea, demonstrating complex nutrient cycles in nature.
Ocean biology also benefits from nutrient-rich dust.
When desert dust settles on ocean waters, it provides essential minerals that stimulate the growth of phytoplankton that form the basis of the oceanic food chain and support a variety of marine life.
Thus, the flow of food from the Sahara could boost marine productivity, affecting fish populations and the global fishing industry.
But the effect of desert dust is not always beneficial, and in ecosystems unusual for the flow of foreign particles and nutrients, the dust can disrupt local environments.For example, excessive dust deposition can strangle corals, block sunlight and hinder photosynthesis.
Moreover, the health effects of desert dust extend across continents, where dust not only carries nutrients but also contaminants and pathogens that can affect air quality and public health.
Communities in the path of these dust plumes may face increased respiratory problems, allergies and diseases, highlighting the need for surveillance and global health preparedness.

Content: A new study by Indian and German scientists has found that aerosols are causing the Himalayas to heat up dramatically, with serious implications for climate change and monsoon patterns in the region.
The study, which included ground observations, satellite data and model simulations, highlighted the high aerosol radiative forcing efficiency (ARFE) over the Indian Ganges Plains (IGP) and Himalayan foothills.
The average ARFE was found to be 2-4 times higher in this region compared to other contaminated sites in South and East Asia.
Aerosols are fine solid particles or liquid droplets suspended in the atmosphere, which can be of natural or man-made origin.
The researchers noted that aerosol-induced warming observed at high altitudes of the Himalayas increases air temperatures, accelerates the retreat of glaciers, and affects the hydrological cycle and precipitation patterns.
The study confirmed that these changes have significant consequences for the summer monsoon in Asia and the melting of snow ice.
The Himalayan region, including the Hindu Kush-Himalaya-Tibet Plateau (HKHTP), is home to the largest ice mass outside the Antarctic and Arctic polar regions.
The observed retreat of glaciers in this region is influenced by atmospheric warming caused by aerosols and the deposition of light-absorbing carbon aerosols on snow and ice.
The researchers warned that this rapid retreat of glaciers would have negative impacts on water supplies in South and East Asia, affecting the regional hydrological cycle.
The study highlights the need for further research and understanding of the impact of aerosols on the Himalayan climate and the larger impacts on climate change and water resources in the region.
It emphasizes the importance of reducing aerosol emissions and mitigating the effects of climate change to protect fragile ecosystems and populations in the HKHTP region.

Content: Climate expert reveals why the decline of the "worst weather appearance" negatively affects Saudi Arabia
Miscellaneous
Copy Link https: / / en.rt.com / x35l
Abdullah Al-Misnad, a climate professor and vice president of the Saudi Weather Association, revealed the reasons for the decline of dust storms that ravage Saudi Arabia every year.
In his account on the platform "X", Abdullah Al-Misnad wrote: "Dust storms are the worst weather manifestation that negatively affects Saudi Arabia and the region in general, at the level of mood, health, education, work, tourism, travel, trade, and even affect animals and plants as proved scientifically. During the year 2023, any sand storm is mentioned in the city of Riyadh, and this necessarily applies to many cities and provinces of Saudi Arabia. ”
He added that this is due in part to: "
• First: Saudi Vision 2030, which accelerated the treatment of environmental degradation in our lands, through the expansion of the nature reserves, which cover 14% of the area of   Saudi Arabia, mostly in the northern areas, and parts of the eastern central, which incidentally is the site of dust storms usually, and these reserves contributed to prevent overgrazing, wood, and also prevent tilling the soil by hikers cars, and trampling vegetation cover. "Through the spread of seeds, and the expansion of the spring area year after year, the earth's crust became more solid and resistant to wind, limiting the spread of dust."
• Second: the succession of rainy seasons during recent years, which contributed to the spread of spring in the scope of reserves and beyond.
Third, the cold and warm air fronts coming with the Mediterranean depressions did not come with the strength and destiny to which we are accustomed, by the grace of God.
On the other hand, dust storms are a natural phenomenon that occurs in many parts of the world and cannot be completely prevented, but their effects can be reduced by taking preventive steps, including the expansion of protected areas, and through the Saudi Green Initiative.
That and God knows. ”

Content: Why is Northern China once again a place of bitterness?
Author: External Submission
Published: Updated:
The northern part of China was once again hit by severe sandstorm weather.
The dust has affected eastern Xinjiang and southern Xinjiang Basin, Inner Mongolia, western Gansu, northern Ningxia, northwestern Shanxi, central Jilin, northern Liaoning, northern China, northeastern China and the Huanghuai.
Due to this, as of 6: 00 a.m. on April 11, Beijing Real-time air quality index is 500, is critical pollution level, and the primary pollutant is PM10.
The Beijing Meteorological Station issued a yellow sandstorm warning. It is expected that there will be obvious sandy weather in Beijing from 21: 00 to 17: 00 on April 10, and the lowest visibility in most areas is less than 1000 meters.
As previously reported in the Anbang briefing, the frequency of dust storms in northern China has increased significantly this year, and it has entered the stage of dust and sand weather.
This article is licensed by Anbang Think Tank.
This large area of sand and dust weather is not limited to northern China, but also all the way south "crazy" across the Yangtze River.
According to the China Meteorological Bureau's meteorological detection center monitoring shows that at 16: 00 on April 11, the dust and dust cluster moved south, and the dust frontier has been to Hubei, Anhui and Jiangsu, and the concentration of PM10 in many places exceeds 1000ug / m3.
The frequent sandy weather in the northern region has made northern China once again a "bittersweet place", and the livability has greatly deteriorated.
If similar sandy weather continues, it will drive more people from the north to the south, and continue to widen the economic development and population distribution differences between the north and the south, which is undoubtedly very detrimental to the development of the north.
+ 8
Why is it that after sticking to the "green water and green mountains" strategy for many years, the northern region is still experiencing large-scale dust storms so frequently? The relevant departments said that "dust and dust weather is generally decreasing", but this argument is difficult to convince, and can not explain the weather changes this year.
From a public policy perspective, researchers at ANBOUND believe that there is a need to objectively look at the formation and effects of sand and dust weather, and then find countermeasures within the limits of human ability.
First, the dust source area is very wide and belongs to large-scale weather phenomena, which goes beyond the protection of the existing ecological environment.
Since this year, there have been eight sandy weather processes in the Mainland.
It is worth noting that this year, the sandy weather in the northern part of the mainland has a wide range of sources, both domestic and foreign.
For example, the sandy weather from April 10 to 11, the sand source is Mongolia and central Inner Mongolia; on March 22, the sand source is central Mongolia and northwest China; from March 14 to 15, the southern part of Mongolia, the border of Central Mongolia and the eastern part of Inner Mongolia continued to sand source; on March 10, the central and southern part of Mongolia and the border areas of China appeared systematic sandy weather; On January 17, dust broke out on the border of China and Mongolia, and the dust gradually moved to the east.
+ 3
From a spatial point of view, dust weather is a large-scale weather phenomenon, small scale local area vegetation improvement and ecosystem restoration, do not play a big role in suppressing dust weather.
Especially when the sand source comes from other regions (such as Mongolia), many parts of the country are basically passive acceptance.
The impact range of the sandy weather, from north to south, spans 2000-3000 km, passing through the relatively dry, less vegetated warm temperate zone and relatively moist, more vegetated subtropical areas.
This means that the efforts of the Mainland to improve the ecological environment and improve the vegetation in local areas are not enough to reduce large-scale dust and dust weather.
Second, frequent sand and dust weather may be related to global warming, which is the result of a combination of short-term and long-term factors.
Some experts said that this year, the dust and dust weather is mainly related to the recent atmospheric circulation. March to April is the northern high wind season.
Under certain windy conditions, the dust from the sand source is transported to China many times, which is the most direct reason for the severe dust weather many times this year.
It is important to note that warming also has an important impact on the production of sandy weather.
According to the China Meteorological Bureau on March 25 this year, it is expected that this spring (April to May), the precipitation from the southern part of Mongolia to the central and western parts of Inner Mongolia is less, the temperature is higher than the same period of the year, and there is a southward influence of the Mongolian cyclone stage, which is conducive to the formation of sandy weather.
Statistics from the National Climate Center show that since late February 2021, the temperature in western Inner Mongolia and Mongolia has been unusually high of 2 ° C to 6 ° C, causing the snow to melt ahead of time and the sand source to be exposed.
The exposed surface of the large area provides sand source conditions for the production of sand and dust weather. In the 2022 vegetation growth season, Mongolia has less precipitation than the same period in the past 20 years, the vegetation cover of the sand source is poor, and the exposed surface lacks vegetation protection.
Environmentalists sit high and watch the police move in Lützellat, Germany, on January 8, 2023.
The following banner says “1.5 ° C means: keep Lützelat! ” 1.5C is a target set by the Paris Agreement to limit global warming to 1.5 ° C. (Thilo Schmuelgen / Reuters)
It is worth noting that global warming is a long-term trend, and the resulting global abnormal climate change is becoming increasingly obvious.
In the past two years, the Northern Hemisphere has experienced unusually high temperatures and dry weather in summer, which has accelerated the melting of glaciers.
According to Swiss research, the size of the Alps Glacier has shrunk by about 60% since 1850.
According to German glaciologists, 2022 is a record year for glaciers to melt.
Due to factors such as rainfall, reduced snowfall and drought, hot weather, the amount of glacier melt in the entire Alps in 2022 is estimated to have increased by about 50% compared to previous years.
In China, in recent years, there has also been an abnormal phenomenon of "drought and waterlogging" in the north and south.
Global warming constitutes the macro background of global climate change, and if there is widespread warming and drought in the northern region, it will lead to frequent sandy weather in the spring.
Third, human activities are still increasing overall, and the impact on the undersurface of the atmosphere is constantly increasing, which is one of the important reasons for catastrophic dust and dust weather.
Although the world and China have increasingly attached importance to ecological protection and climate change issues, on the whole, human activities - industrial activities (such as industrial production, large-scale mining, etc.), urbanization, life consumption activities, war and other man-made factors, the changes and impact on the atmospheric surface are constantly increasing, resulting in the artificial intervention of the atmospheric surface is constantly strengthening, and the ecological destruction and soil desertification in local areas are constantly increasing.
These changes can be an important reason for the increase in catastrophic dust weather.
Objectively speaking, in recent years, the vegetation in northern China has increased significantly, and the ecological environment has improved significantly, which is generally conducive to the gradual reduction of the number of sand and dust in China.
However, ecological destruction in other countries (such as Mongolia) and surface features such as the Gobi Desert are also important sources of dust affecting China.
The final analysis conclusion:
This year ’ s significant increase in sand and dust weather constitutes a force majeure in China ’ s environmental problems.
As a large-scale weather phenomenon, the generation and impact of sand and dust weather are beyond the ecological environment improvement efforts of small scale and local areas.
In order to reduce the occurrence of sandy weather through human efforts, this is more difficult and complex system engineering than ecological governance at the national or regional level, and requires global or regional countries to strengthen cooperation to continue to curb the trend of climate warming, or cooperate to change the regional ecological environment.
For China, which is more affected by the continental climate and monsoon climate, it is feared that it will suffer the effects of catastrophic weather similar to sand and dust for a long time, which will have a greater negative impact on economic activity and livability in northern China, and may continue to widen the economic and social development gap between the north and the south.

Sahara desert dust storms carry harmful bacteria and fungi around the globe

We often dismiss springtime allergies as reactions to local pollen. Yet, something else might cause our sniffles and sneezes: a massive dust storms that originate thousands of miles away in Africa’s Sahara region.

These gargantuan dust plumes travel the globe every summer, carrying a cocktail of pollutants and potential pathogens across continents.

Dr. Shankar Chellam, a Texas A&M University professor is leading the charge to understand the biological hitchhikers within dust storms.

He and his team are working to determine what microbes, specifically bacteria and fungi, migrate with the dust and explore their potential impact on human health.

Hidden passengers in Sahara dust

“We all get allergies and potentially other more severe health effects when we breathe in dust, and it’s not fully known as to what causes those allergies,” said Dr. Chellam.

“Some people may think it is just the sand or clay minerals in the dust. Others think it is the metals or organics in the dust, and then some think it’s the bacteria and fungi.”

The Saharan dust cloud carries vast amounts of sand particles that transport bacteria and fungi.

Dr. Chellam’s research uniquely addresses how Saharan dust storms introduce these microbes into North America.

What the dust storm from Sahara tells us

Dr. Chellam and his team analyzed samples from a Saharan dust event that reached Houston in 2018. They measured metals, bacteria, and fungi to investigate any connections.

Fascinatingly, their findings revealed strong links between the biodiversity of the microbes and specific elements, especially calcium.

While these elements occur naturally in the Sahara, they also exist in our local environments. Pinpointing the exact origin of the dust and its cargo remains a challenge that scientists continue to tackle.

Our air – Not as empty as we think

Perhaps the most startling discovery is that even seemingly lifeless clouds of dust brim with biological activity.

“A key takeaway from this study is that a lot of biodiversity is not scientifically described. It doesn’t have a name, it can’t be cultured, and because it can’t be cultured, it’s difficult to study,” explained Dr. Daniel Spalink, assistant professor at Texas A&M.

The team’s high-tech DNA analysis allowed them to create an inventory of bacteria and fungi, even if the microbes themselves weren’t active.

Surprisingly, they found traces of several pathogens known to cause disease in humans, as listed by the World Health Organization (WHO).

“It doesn’t tell us if they are going to be able to infect us and make us sick,” Spalink cautions, “But at least the DNA of several pathogenic bacteria and fungi were identified in the African dust.”

Impact of climate change on Sahara dust

Climate change is altering weather patterns globally. This transformation affects dust storm behavior, leading to variations in their frequency and intensity.

In 2020, the United States experienced the most massive Saharan dust storm ever recorded, which experts named “Godzilla.”

This event highlighted the potential for increasing occurrences of such dust invasions. “The whole dynamics of the Saharan dust coming to Houston is primarily driven by atmospheric processes,” said Dr. Sourav Das, a former student of Dr. Chellam.

Global connection of Sahara dust

Sahara dust storm travels far beyond the borders of North America, affecting global environmental systems in profound ways.

This dust, originating from the vast Sahara Desert, embarks on transcontinental journeys that influence climate, ocean biology, and ecosystems far removed from its source.

The Saharan dust plays a critical role in climate regulation. As it travels across oceans and continents, it reflects sunlight back into space, cooling the Earth’s surface.

This natural phenomenon acts as a counterbalance to the warming effects of greenhouse gases, showcasing how desert dust can influence global temperatures.

However, the dust also carries microorganisms and nutrients, such as phosphorus, that fertilize remote ecosystems, from the Amazon rainforest to the Caribbean Sea, demonstrating nature’s complex nutrient cycles.

Benefits to oceans

Ocean biology benefits from the nutrient-rich dust as well. When Saharan dust settles on ocean waters, it delivers essential minerals that stimulate the growth of phytoplankton.

These microscopic plants form the foundation of the oceanic food chain, supporting a diverse array of marine life.

The influx of nutrients from the Sahara can thus boost marine productivity, affecting fish populations and the global fishing industry.

Disadvantages

The impact of Saharan dust is not universally beneficial. In ecosystems unaccustomed to the influx of foreign particles and nutrients, the dust can disrupt local environments.

For example, excessive dust deposition can smother coral reefs, blocking sunlight and hindering photosynthesis. This can stress coral ecosystems, leading to bleaching events and loss of biodiversity.

Moreover, the health implications of Saharan dust extend across continents. The dust carries not only nutrients but also pollutants and pathogens that can affect air quality and public health.

Communities in the path of these dust plumes may experience increased respiratory issues, allergies, and diseases, highlighting the need for global health monitoring and preparedness.

Study insights

It’s crucial to gather data across multiple dust events, spanning many years, to get a clearer picture of these airborne microbial communities and how they might transform over time.

While a lot remains unknown, research like this shines a spotlight on the hidden travelers swirling in the air we breathe — travelers who might be affecting our health in surprising ways.

The next time you catch a glimpse of a dust storm rolling in, remember the globe-trotting microbes it carries!

The findings of the study are published in Environmental Science & Technology.

Layer of Saharan dust will affect the Bahamas by the weekend

By EARYEL BOWLEG

Tribune Staff Reporter

ebowleg@tribunemedia.net

RESIDENTS are urged to “safeguard their health” as a plume of Sahara dust moves over the south-east Bahamas.

The Department of Meteorology said the dust will gradually move across the country this weekend.

It warned the dust could be problematic for people with allergies and respiratory issues.

“Sahara dust is made of sand, dirt, and other dust particles that are lifted into the atmosphere from the vast Sahara Desert in Africa,” the advisory said.

Acting director of meteorology Jeffrey Simmons told The Tribune the dust tends to appear around this time every year.

He said the dust has lingered around southeastern islands for the past week, prompting some to complain about allergies.

“That’s the reason, you know, why we put out this warning alerting people about it, people who have these allergy issues or any respiratory issues so that they could, you know, be aware of the impact this could have on them for this weekend and possibly going into another week or two,” he said.

Content: Hurricane Killer? Here are some things you may not know about Saharan dust

Dust from Africa moves across the Atlantic every year from late spring to early fall

It’s a common visitor in the summer months: dust from the Saharan Desert. Hazy skies and occasional allergies are common issues caused by the dust. But did you know that this layer of dust is more interesting than it appears? Here are some things you may not know about Saharan dust:

KEY TAKEAWAYS

  • Millions of tons of dust are transported across the Atlantic every year
  • Nutrient-rich Saharan dust plays a crucial role in the global ecosystem
  • Dust suppresses hurricane development

WHOLE LOTTA DUST!

Every year, from late spring to early fall, trade winds transport 180 million tons of dust from the Saharan Desert across the Atlantic Ocean. Impressively, that’s as much as 4.5 million 18-wheelers full of dust!

NATURE’S BEST FRIEND

Saharan dust is often rich in nutrients like iron and phosphorus. As the dust settles over the ocean, it fertilizes algae and plankton, allowing them to grow and flourish in an otherwise barren environment. These organisms are vital sources of food for ocean life.

Similarly, as the dust settles over land, areas like the Amazon rainforest benefit from the extra nutrients.

HURRICANE EXTINGUISHER

The African dust that moves across the Atlantic Ocean is also called the Saharan Air Layer (SAL). The SAL occurs in waves at the same time as Atlantic hurricane season, from June through November.

It’s known that the SAL limits hurricane development and strength. This is because tropical storms like hurricanes need deep, rich moisture from the surface to the top of the atmosphere to survive. Since the air carrying Saharan dust is usually dry, it can prevent storms from forming and suppress existing storms from growing and strengthening.

DUST’S IMPACT ON TEXAS

While a dense plume of dust sometimes causes minor allergy-like symptoms for some, the most noticeable impact is on Texas skies. A haze often forms on the horizon, giving an ordinarily clear, blue sky a milky hue during the day.

At sunrise and sunset, the horizon can appear brilliantly orange because, with dust in the air, sunlight has more particles to bounce off.

NASA Satellites Capture Desert Dust Column Over Atlantic Ocean
Thank you for reading the news about NASA technology: NASA satellites pick up a column of desert dust over the Atlantic Ocean and now with the details
CAIRO (Reuters) - NASA satellites have revealed that July is a particularly windy month in sub-Saharan Africa, with large plumes of dust being pulled across the Atlantic toward the United States and the Caribbean.
NASA ’ s Aqua satellite captured images using the Moderate Resolution Imaging Spectrometer (MODIS), where these natural-color images spotted a huge dust plume hovering off the desert over the ocean, stretching between the Canary Islands and Cabo Verde.
The Aqua satellite is part of the International Earth Observation System (EOS) and studies the water cycle, and although this particular image was taken on July 26, Aqua and other satellites captured many similar events over the course of the month, indicating a more active month than usual.
About 182 million tons of dust blow across the Atlantic each year, and play an important role in the Earth ’ s climate system.
Dust columns as they travel through the air, dust particles absorb and reflect sunlight, contributing to the planet ’ s overall thermoregulation, and creating a dramatic sunset, which has been seen throughout Florida, Texas, and the Caribbean over the past month.

Content: Saharan dust reaches stunning levels in Atlantic. Here's what that means for hurricane season

Significant Saharan dust plumes are common in the Atlantic during the start of hurricane season. If levels of SAL maintain a steadiness after about Aug. 20, then there would be significant ramifications to both the amount of cyclones and their overall strength.

First, Europe that was socked in by record levels of dust from the Sahara Desert in Africa. The Atlantic appears to have now taken the lead, with dust levels not seen in years across parts of the basin.

Satellite measurements indicate intensive plumes of dust, called the Saharan Air Layer, across much of the eastern Atlantic. Traces of dust have even made the more than 4,000-mile journey to Florida and the Gulf Coast.

Sunrises and sunsets have been enhanced across the Sunshine State as the particles scatter typical colors, allowing hues of orange, yellow and red to dominate the sky.

Aside from the vibrant colors, something not falling from the sky is precipitation.

According to NOAA, the air surrounding the SAL has about 50% less moisture than the typical atmosphere. This means the presence of the SAL can be detrimental to cloud formation and thunderstorm activity.

Significant plumes of dust and dry air are common during the first months of the hurricane season and usually persist through mid-August.

A LOOK AT A PHENOMENON THAT COULD DERAIL AN ACTIVE HURRICANE SEASON

How Saharan dust impacts hurricane season

NOAA estimates that more than 180 million tons of dust leave the African continent every year, reducing thunderstorm activity and tropical cyclone formation.

Dry air and Saharan dust are perennial wild cards in tropical weather outlooks, as meteorology has yet to develop sufficient methods to forecast plumes weeks and months in advance.

Years with significant dust often experience reduced cyclone activity. Seasons with minimal dust typically rank at the top echelons of activity, thanks to increased moisture availability for tropical systems and warmer water temperatures.

The current season is a bit unusual as water temperatures started on the warm side across much of the basin, negating any minor effects from a dust storm.

Warm waters and limited exposure to dry air helped with the formations of AlbertoBeryl and Chris during late June and early July.

Since Beryl’s historic trek through the Caribbean and into the Gulf of Mexico, the basin has been relatively quiet, a likely product of the increase in dry air.

The trend for limited activity in the Atlantic basin is expected to continue for the foreseeable future, meaning that the next cyclone formation may be weeks away.

5 THINGS TO KNOW ABOUT THE SAHARAN DUST PLUME

During an average year, the fourth-named storm usually doesn’t form until about Aug. 15, meaning any formation during the next month will keep the season ahead of a typical schedule.

Despite the hostile conditions in the Atlantic, hurricane forecasters at Colorado State University maintain that 2024 will be a busy season in the Atlantic.

CSU released its updated outlook Tuesday, which calls for an additional 22 named storms, 11 hurricanes and five major hurricanes.

"This forecast is of above-normal confidence. We anticipate a well above-average probability for major hurricane landfalls along the continental United States coastline and in the Caribbean," CSU forecasters stated during their most recent tropical update. "As with all hurricane seasons, coastal residents are reminded that it only takes one hurricane making landfall to make it an active season."

The season runs through Nov. 30, but nearly 60% of cyclone formation occurs in August and September.

"The area of interest off the coast of Africa has a low chance of development over the next five days."

Content: This weekend marks the peak of the Atlantic Hurricane Season. This is typically when the Atlantic is most active for tropical systems. This year, however, the Atlantic looks to be settling down, at least for the time being.

Not too long ago the Atlantic was busy with Hurricane Danielle, then Hurricane Earl forming. Both of those storms remained out in the open Atlantic away from the United States. Now that Danielle has faded and Earl is moving away, there are not as many areas to watch in the Atlantic.

The latest Tropical Update

For now, there is only one area of interest off the coast of Africa. This area only has a low chance of development over the next five days. This doesn’t mean that another storm won’t form in the days to come, but it is possible that we will see a lull in tropical activity.

Saharan dust continues to be a limiting factor for storm development. This dry, dusty air limits and chokes off thunderstorm development in the Atlantic. Thus limiting the number of tropical systems. For now, more Saharan dust is expected to move out into the open Atlantic, hindering any tropical development over the next few days.

While presently there are factors that are limiting tropical development in the Atlantic, there is still half of the season left to go. We still have time for conditions to change and for more storms to develop later on.

The Weather Authority will continue to monitor the topics and bring you the latest.

"The Saharan dust is expected to hinder tropical development in the Atlantic over the next few days, but a specific forecast for the area of interest is not provided."

The tropics will continue to remain quiet across the Atlantic basin over the next upcoming five days. Conditions remain too hostile to allow for tropical formation in the main development zone of the far tropical Atlantic waters. One of the factors limiting potential formation is the presence of dry air and Saharan dust. Some of that dust may try to reach our local skies this week which may possibly allow for some more vibrant sunrises and sunsets, and perhaps creating more of a haziness in the sky. It's not a guarantee it can fully reach the Big Bend and South Georgia, but it's an interesting feature to observe outside!

On average over the last century, hurricane season trends on the quieter side during the month of July. By mid-August, activity typically picks up and increases through mid-September. The season peaks around September 10th.

Research shows that dust storms coming from the Sahara Desert can severely damage solar energy production.
So, what can be done to better manage this problem?
Climate Now reports from Andalusia on efforts to beat the dust.
Announcement
On this month ’ s episode of Climate Now, we set out to southern Spain to report on the growing problem of Sahara dust, which has a significant impact on solar power generation.
Our visit to southern Spain comes as the Copernicus Climate Change Authority announced that we have seen the highest ever recorded temperature for May 2024, registering a temperature rise of 0.65 ° C above the 1991-2020 average.
This is the 12th consecutive month with the highest recorded temperature for the month in question.
In May 2024, we witnessed extreme weather conditions in many areas.
Floods in Brazil have displaced more than half a million people, temperatures in the Delhi region of India hit 49.9 degrees Celsius, its highest recorded to date, and Finland issued a heatwave warning of temperatures rising to more than 27 degrees Celsius.
In Europe, heavy rains led to flooding in southwestern Germany, Belgium, and northern Italy.
Massive losses in solar power generation due to Sahara dust
The dust of the Sahara Desert in Europe is famous for turning its skies orange, which reduces air quality and leaves a fine layer of dust on the roofs of homes and cars.
On the other hand, it causes another growing problem known as “dirty ” solar cells.
At Gianni University in Andalusia, we met with Dr. Eduardo Fernández and Professor Florencia Almonacid, who were among the authors of a recent paper that found that the severe dirt on the panels in March 2022 reduced solar capacity by up to 80 percent.
Dr Fernandez told Euronews: “It felt like we were on Mars where everything turned red. ”
March 2022 saw extreme weather, but even small amounts of dust could reduce the amount of sunlight reaching solar cells by 15%, and with the rapid growth of solar energy in Europe, losses from dirt could account for billions of euros a year.
Therefore, the research team at Jian University is using photovoltaic laboratories to find solutions.
Some scientists focus on developing dust-resistant layers, while others look at how dust accumulates with different weather conditions, such as high and low temperatures, and low rainfall.
There are many variables that need to be taken into account.
For example, dust grains may be of different sizes or colors, and can affect how well solar panel installations perform.
Even design elements make a difference, such as whether a painting is frameless or has a solid lip around its tip.
Professor Almonacid says that Sahara dust is particularly problematic: "Sahara dust particles are very fine.
It ’ s especially hard to clean. ”
The Cost and Benefit Dilemma of Solar Panel Cleaning
Renewable energy company Sonnedix faces the grime challenge every day, monitoring production from each solar power generation site and carefully calculating when cleaning PV panels is commercially feasible.
The cost of cleaning is considerable – around €400-500 per megawatt – so there are difficult choices to make depending on how the power plant is priced.
Joanne Fernandez, chief operating officer of the company, told Euronews: “As you generate electricity, every kilowatt-hour is important for the plant ’ s revenue, so this dust weather has a big impact. ”
He is now working with meteorologists to help plan cleaning sessions according to dirt weather conditions, and the amount of rainfall, as light spray may increase the soiling of the panels, and heavy rain may wash them away for free.
“Severe dust storms coming from the Sahara desert could actually lead to a significant reduction in production within the network, and this could cause a significant problem for the network operator, ” he explains.
“So forecasting, forecasting, and the ability to proactively manage the network is the most important, ” he says.
Announcement
Have dust storms from the Sahara increased due to climate change?
The recent increase in dust storms coming from the Sahara desert could be the result of natural climate variability, or it could be caused by something else.
A spokesman for the Copernicus Meteorological Authority told Euronews: “Although the arrival of dust plumes from the Sahara to Europe is not unusual, there has been an increase in the intensity and frequency of such weather conditions in recent years, and may be attributed to changes in atmospheric circulation patterns. ”
There is some speculation that these changes in atmospheric air circulation patterns are linked to climate change.
Dust expert Dr. Eduardo Fernandez says: “Scientists are always cautious about drawing conclusions, and that should be the case, right? ”
“But what we ’ re seeing is that there ’ s been a dramatic increase in extreme weather conditions, not just in terms of slabs getting dirty, but also in terms of rainfall and wind blowing.
“We are recording more dust storms coming from the Sahara, and they are increasingly penetrating into larger areas in northern Europe, and there is, of course, suspicion that global warming is the cause, ” he concludes.

Khamasini air depression coinciding with Eid al-Fitr holiday
The results of the analysis and computer simulation data of weather forecasts at the Arab Weather site indicate the forecast of the movement of the air dew from the Libyan territory, taking a path inland from Egypt to Iraq through the Levant, and is expected to impose significant weather fluctuations between a significant rise in temperatures followed by a significant decrease in temperature and dry and dusty atmosphere in many areas.
According to the latest weather map readings, the low quintet is expected to affect many Arab countries: Libya, Egypt, Jordan, Palestine, Lebanon, Syria, Iraq, Saudi Arabia and Kuwait, during the Eid al-Fitr holiday.
The same maps indicate the expected concentration of the Khamasini depression on Monday (the first day of Eid astronomically) east of the Libyan territory, leading to the control of heavily dusty atmosphere in the south, east and possibly parts of northeastern Libya in conjunction with the occurrence of major turbulence in the sea and rising waves.
This also results in dust waves in western Egypt and a rise in temperatures throughout Egypt turning the weather hot.
There is also a clear rise in temperatures in the Levant to become higher than their rates for this time of year, and the weather turns to become warm over the mountains and tilted to heat in the rest of the regions.
The depression is moving towards the northwest of Saudi Arabia through the Jordan desert on Tuesday, which means that the five-year weather conditions have moved to Sinai, Palestine and Jordan, so it is expected that the dust levels in the atmosphere will increase in conjunction with the predominance of relatively hot weather throughout the main areas of the Levant.
Heavy sandstorms are expected on desert roads in Jordan, including the road leading to Aqaba and border crossings with Saudi Arabia.
Temperatures are rising in northwestern Saudi Arabia with sandstorms expected in those areas.
On Wednesday, 4 / 5 / 2022, the air dew is positioned east over the Iraqi territory, and the wind turns to become westerly wet on the Levant and northern Egypt, thus reducing temperatures throughout the Levant and Egypt, God willing, and at the same time increasing temperatures in large parts of eastern, central and northeastern Saudi Arabia, Iraq and Kuwait.
Why are depressions forming at this time of year?
Pentathlon depressions are known as thermal depressions that usually form in the spring in the northern part of Africa (in the Sahara), moving parallel to the Mediterranean coast towards the eastern Mediterranean basin and the Levant region.
A low temperature is defined as a low caused by the extreme heating of the Earth's surface, which results in a low density of air above it, rising up and reducing pressure, and air begins to accumulate from high pressure areas towards low pressure areas, forming an upward movement that is in a narrow space vertically.
The five depressions in the Sahara and North Africa are formed during this period of the year (spring period) as a result of the decrease in atmospheric pressure due to the high temperature there compared to the temperature of the Mediterranean Sea, which becomes cold after winter, pushing the dust-laden surface winds from the Sahara to the east.
The quintet depressions are usually accompanied by the quintet winds, which are mostly southwestern, dry and warm and come from the Sahara desert loaded with tons of dust and dust raised, and move quickly towards the eastern Mediterranean regions such as Egypt, the Levant, Iraq and the Arabian Peninsula, operating at a rapid rise in temperatures and a dusty atmosphere that reduces visibility.

CAMS monitors Saharan dust transport across western and central Europe

Aerosol forecasts from the Copernicus Atmosphere Monitoring Service present a big amount of Saharan mud transferring northwards throughout Europe over the following few days. CAMS continues to watch the Saharan mud transport following current forecasts that confirmed the very best values over western Europe between 15 and 17 March 2022. The CAMS forecasts additionally present degraded air high quality throughout giant components of Spain, Portugal and France associated to the Saharan mud transport.

Copernicus Atmosphere Monitoring Service (CAMS) forecasts since 11 March have been exhibiting a big plume of mud with very excessive values of aerosol optical depth (AOD) and mud concentrations travelling northwards throughout the Iberian Peninsula, France and central areas of Europe between 15 and 17 March. The trajectory of this mud plume has resulted in very excessive predicted floor concentrations of PM10 as much as 250 micrograms per cubic metre, though European Environment Agency measurements have been exhibiting values in extra of this at many websites throughout Spain on 15 March. This is larger than the EU beneficial 24-hour imply threshold of fifty micrograms per cubic centimetre.

CAMS tracks all levels of mud transport from the Sahara Desert yearly and has been monitoring the annual mud transport, from completely different supply areas throughout the desert, for the reason that starting of the 12 months. CAMS forecasts are offered at each the European and global scale, and function a instrument to assist residents, companies, and policymakers make knowledgeable selections on a steady foundation with 24/7 air high quality forecast information. Air high quality is recognised as being very important to human well being as excessive concentrations of mud can have well being impacts on the respiratory programs of all individuals within the affected areas and add to particulate matter air air pollution from native sources. Senior Scientist, Mark Parrington, on the ECMWF Copernicus Atmosphere Monitoring Service feedback: “In CAMS we use satellite and in situ observations in our air quality forecasts to be able to provide a continual and reliable source of information for monitoring air pollution events such as this. Long-range transport events such as this occur most years and the impacts of the current event is quite striking. While the dust will affect air quality in parts of southwest Europe, the larger scale impacts will be hazy skies or some surface deposition.” You can discover extra data on the CAMS monitoring of this 12 months’s Saharan mud season right here: https://atmosphere.copernicus.eu/saharan-dust-heads-north-cams-tracks-its-progress-nfAdditional air high quality information will be discovered within the Atmospheric Data Store (ADS):https://ads.atmosphere.copernicus.eu/cdsapp#!/dataset/cams-global-atmospheric-composition-forecasts?tab=overviewandhttps://ads.atmosphere.copernicus.eu/cdsapp#!/dataset/cams-europe-air-quality-forecasts?tab=overview

Heat relief heading for NY — other parts of US aren’t as lucky

After soaring temperatures baked the Big Apple this week, New Yorkers will see some relief in the coming days while other parts of the country won’t be so lucky.

“After a couple of toasty days up here in the Northeast that I am glad are behind us, we’re back to about average,” Fox Weather meteorologist Christopher Tate told The Post Saturday.

The thermometer was in the mid-80s Saturday afternoon, though high humidity helped the “real feel” temp reach as high as 99 degrees in some parts of the city.

Temps should stay in the 80s for the next few days, flirting with 90 degrees later in the week in the five boroughs, Tate said.

But summer thunderstorms will provide some relief.

Central Park should see a couple of heavy thunderstorms overnight and on Sunday. A flash flood alert is in effect for the Northeast due to rainfall forecast from Sunday through Tuesday.

Around New York City, the greatest risk of flooding will be from Sunday evening to early Monday, according to AccuWeather.

“I wouldn’t be surprised if we see an occasional report here or there of some standing water causing some issues or maybe some drains getting backed up but it shouldn’t be anything major,” said Tate.

Monday should be clearer, but Tate couldn’t promise there won’t be some thunder.

The southeastern United States, which experienced a blistering heat wave this week, will also get some relief, but at the expense of severe storm threats and a cold front rolling through.

The deadly heat throughout the Desert Southwest, however, will drag on, with 110-plus degree heat stretching past two weeks.

“They’re setting up for what could be one of the longest stretches of 110-degree or higher high temperatures, potentially even on record,” said Tate. “That would get them into territory where they would rival past heat waves, even by Southwest standards.”

Hot air is less dense than cold air, Tate explained, which could impact air travel in the area because it is harder to lift planes.

“Southwestern airports, notably including Phoenix Sky Harbor International Airport may have difficulties getting especially large aircraft off the ground,” he said.

And while it might feel like the Sahara in parts of the country, Florida is actually getting a piece of the African desert. A layer of Saharan dust is settling on the state, caused by strong winds that carry small sand particles from the Saharan Desert far across the Atlantic Ocean, the Miami Herald reported.

While it can make for colorful sunsets, it can be harmful to people with asthma and other respiratory issues.
