La Niña Advisory update: pattern could continue this fall, possibly drop in strength heading into winter

The current La Niña will continue for the rest of the summer, lasting into the fall, but possibly decreasing in strength before the 2022-2023 winter season begins.

BUFFALO, N.Y. — In a recent update from the Climate Prediction Center, climate forecasters expect the current La Niña conditions present over the eastern Equatorial Pacific Ocean to continue this fall.

But they hinted at the potential for the event to slowly decrease in strength heading into the Northern Hemisphere wintertime months.

Forecasters noted how the presence of below-average sea surface temperatures actually expanded in area within the past month. Upwelling from Kelvin waves over the east-central Pacific Ocean enhanced the depth of the cooler water temperatures that are a staple of La Niñas. Couple that with a La Niña sea to air pattern, this La Niña shows no sign of slowing down over the next few months.

And with the peak of the Atlantic Hurricane season fast approaching, the importance now turns to how the existing La Niña could impact the rest of the season. It's been a very quiet start to the season so far with only three named storms since June 1st. In fact, from July 3rd through August 15th there was no mention of any tropical activity. This is because of Saharan Dust that limited tropical cyclone development over that 6 week period.

That being said, NOAA and the National Hurricane Center (NHC) are still predicting an above average Atlantic Hurricane season for the remainder of it. This is due to, in part, the existing and continuing La Niña as well as other factors like the onset of the West African Monsoon and weaker trade winds over the Atlantic Ocean.

El Niño Southern Oscillation (ENSO) is a large, naturally occurring ocean to atmosphere phenomenon located over the equatorial Pacific Ocean. Its positive phase is an El Niño and negative phase is a La Niña. It's closely monitored year round as it can influence weather patterns across the Northern Hemisphere, especially during the fall, winter and even spring months.

Storm Team 2 will be keeping a close eye on the existing La Niña over the next few months to see if it could potentially impact this winter across Western New York.

Content: Hurricane center begins tracking a system in the Caribbean

·2 min read

ORLANDO, Fla. — The National Hurricane Center has been jumping around the last few days tracking short-lived systems with the potential to form into a tropical depression or storm. Late Monday, the NHC began looking at the Caribbean Sea.

As of the NHC’s 8 p.m. Eastern time tropical update, a tropical wave located in the central Caribbean is forecast to move across Central America and emerge over the southwestern Gulf of Mexico where it could develop into the season’s next named system.

“Some gradual development of this system is possible thereafter as it moves slowly to the northwest or north-northwest over the southwestern Gulf of Mexico by this weekend,” said NHC hurricane specialist Philippe Papin.

The NHC gives the system a 20% chance of formation in the next five days.

The Caribbean system follows the NHC keeping track of a broad trough of low pressure in the mid-Atlantic late Sunday, but its chances of formation dropped to 0% by Monday morning. Over the weekend, the NHC tracked a system in the Gulf of Mexico, but it failed to form into more than a spate of showers and thunderstorms that drenched southeastern Texas. Before that, a system off the African coast showed some signs of development before environmental factors snuffed its chances.

Part of the reason for what prevents tropical storm development is the dry conditions in the Atlantic. A large migration of African dust, the Saharan Air Layer, or SAL, is the main reason tropical moisture isn’t at the ideal level for development. Large dust plumes are still pushing west of Africa and into the Caribbean, preventing the Atlantic basin from becoming a hurricane nursery, the National Oceanic and Atmospheric Administration’s SAL forecast shows.

Hurricane season is approaching its peak, which runs from mid-August to mid-October, with Sept. 10 recorded as the statistically most productive day of storms in the tropics.

So far, the 2022 season has seen three named storms: Alex, Bonnie and Colin. Based on historical averages, the fourth named storm of the year typically appears by Aug. 15. If a system were to emerge, it would receive the name Danielle.

Last week, the National Oceanic and Atmospheric Administration reaffirmed its preseason prediction of an above-average hurricane season with a range of 14 to 21 named storms. The NOAA expects most of those storms to emerge at the peak of the season.

Hurricane season ends on Nov. 30.

How does Saharan dust affect immediate weather?

Saharan dust affects North American climate indirectly and has a variable impact on South American climates.

Sahara dust storms carry harmful bacteria and fungi globally into North America.

Title:

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.

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.

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.

San Antonians may want to stay indoors next week. Here's why.

A noticeable change in the air will arrive to the Alamo City next week.

SAN ANTONIO — San Antonio skies could look quite different next week but not in the way we're hoping for.

As San Antonians eagerly wait for rain to break our triple-digit temperatures another common occurrence will pick-up next week known as Saharan dust.

The dust is a combination of sand and dust traveling from North Africa across the Atlantic that peaking in late June through mid-August.

Light amounts of Saharan dust have arrived to the Alamo City this past week but will become more noticeable. Therefore, if you have asthma, COPD or any other type of respiratory illness you will want to stay indoors as much as possible during this time.

Timing of Saharan dust:

Monday - Little changes will be in the forecast as heavier amounts of dust remain over the gulf coast.

Thursday - As the week progresses dust levels continue to rise and could affect air quality levels. For those with any respiratory illnesses they should avoid outdoor activity including vigorous exercise. Also try to keep windows and doors closed. We will continue to monitor this development next week.

Content: Older Barbadians being diagnosed with asthma Loop Barbados

The content originally appeared on: Barbados News

Head of the Queen Elizabeth Hospital’s Respiratory Unit, Dr Dawn Alleyne, says more Barbadians are being diagnosed with asthma later in life, in their 40s and 50s.

Dr Alleyne, who is a Pulmonologist/Intensivist and Head of the Department of Medicine at the hospital, said the incidence of asthma in the Caribbean, including Barbados, had increased 17-fold since the 1970s. She added these trends are correlated with the increase in Sahara dust plumes and the frequency of the dust in the atmosphere.

She further noted that about 20 per cent of the local population had asthma. This meant the condition was quite common.

Due to climate change, dust events have been increasing. The dust, which traditionally visits from June to August, is now being seen in March or April.

The Pulmonologist/Intensivist said traditionally in Barbados, persons presented with asthma in childhood and either grew out of it as they got older, or lived with it as adults. However, this has changed.

“On a day-to-day basis when we conduct clinics, either [in my private practice] or at the hospital, I meet lots of people with severe lung diseases of all types, especially people with asthma. And several of my asthmatic patients have recorded quite clearly in their diaries that they’ve had challenges when we get the situations where we have cars covered in grey dust. Generally, those are the heavy Sahara dust days.

“A lot of the patients are now having to reach for their rescue inhalers, the Ventolin and Berotec inhalers because the asthma condition which generally has been stable, seems to deteriorate during the periods of times when we have lots of dust in the atmosphere,” Dr Alleyne stated.

The respiratory expert shared that persons usually presented with a gamut of symptoms when dust events occurred. These include itchy eyes, runny nose, soreness of the throat, coughing, especially at night, and wheezing.

Those who have chronic lung diseases, such as interstitial lung disease and chronic obstructive lung disease, also complain of increase in shortness of breath on the days in which there is a heavy dust cover,” she said.

She added that people who are not asthmatics should pay close attention to symptoms, such as chest tightness, when there is exertion, allergic rhinitis, eczema, snoring at night or allergic conjunctivitis. These persons could have an increased risk of developing asthma, she stated.

Dr Alleyne noted the situation was not unique to Barbados but could be seen across the world wherever the Sahara dust is being disseminated.

“So, you look at studies from Spain, Italy, the United States, and the French Caribbean. Throughout these areas, people are reporting an increased incidence of Sahara dust plumes, increased incidence of deterioration of asthma control, and patients are being hospitalised for not only respiratory illnesses, but also cardiovascular illnesses. So, the Sahara dust situation really is one that we really need to look at, not just as a hazy day and a sunset that’s not quite clear but really the impact that it is having on health in general, and we need to take it quite seriously.”

In the case of cardiovascular diseases, she said research show that the dust seems to affect the cardiovascular system adversely.

She explained that while larger dust particles are usually deposited pretty high in a person’s airway, causing sneezing and coughing, the smaller ones had the potential to enter the bloodstream and cause inflammation, which can be a precursor to cardiovascular events.

Dr Alleyne also suggested that Barbados implement a Sahara dust warning system, much like the one that exists in Trinidad, where they give accurate accounts of the air quality index. She said it could help people with respiratory conditions prepare and protect themselves better.

“So, I’m hopeful that in the future, we’ll be able to get something that tells us these are the exact numbers and to give warnings to specific categories of people. I think that will be very helpful,” the Pulmonologist/Intensivist stated.

Storm Resiliency And Response Checklist For Energy Utilities

(MENAFN- 3BL) Storm Resiliency and Response Checklist for Energy Utilities: Are You Ready?

Floods, hurricanes, tornadoes, earthquakes and wildfires pose dangerous threats to critical infrastructure. In the wake of these natural disasters, the essential nature of the services that energy utilities provide becomes even more obvious. Service outages during extreme weather events threaten public health and safety and disrupt the economy. Without power, families can't heat their homes amid sub-freezing temperatures. Interruption of the power grid poses a significant threat beyond just financial loss and damage to reputation; the operational integrity of this critical infrastructure is vital to the community, and any disruption could endanger lives.

It keeps energy utilities up at night: a major storm has rolled through, and customers are without service. Systems need to be back up and running again as soon as possible. By adopting a proactive approach, it's possible to mitigate the risk of service disruptions. Energy utilities should consider the following four steps on the resiliency-bolstering journey: Plan, Prepare, Respond and Recover.

Step 1. Plan

Disasters are cyclical. The main goal of resiliency is to break the cycle so that the impacts of the next disaster are less severe for people and property. Planning and preparation may seem synonymous, but in this context, planning refers to actions taken years if not decades ahead of time. Consider the way we prioritize our personal health and well-being: while visiting an emergency doctor may be necessary on rare occasions, making preventative care visits to a primary physician lowers the risk of unforeseen health crises. Similarly, safeguarding our critical infrastructure requires a proactive approach centered around prevention. In the planning phase, it's critical for energy utilities to evaluate weather-related risks, identify vulnerable assets and infrastructure, and determine what can be done ahead of time to mitigate these risks.

New Infrastructure: Design for Resiliency

Although retrofits and repairs are unavoidable in some cases, the ideal strategy is to consider storm resiliency at the time of design and construction – going back as far as the site due diligence and land use planning stages. Before embarking on the development of critical infrastructure such as transmission lines or substations, consider the geographical features, elevations, and water levels of the proposed site. For ongoing construction projects, implement strategies to protect assets and equipment. Flood plains and shorelines are shifting, so assets close to waterways should consider a hydrology study and coastal terrain mapping. Energy utilities may also want to consider a long-term approach to undergrounding their power lines in regions prone to weather-related disruptions; underground lines are less vulnerable to storm damage, falling debris and other environmental factors that cause outages.

Existing Infrastructure: Mitigate Impacts

Aging infrastructure tends to be more at-risk; it's recommended to perform routine inspections and maintenance of rights-of-way. Develop a comprehensive hazard mitigation plan that includes a thorough risk assessment, operational optimizations, disaster procedure development, personnel training, and technology upgrade recommendations. Procure essential replacement parts and equipment ahead of time to avoid supply chain disruption in future emergencies. Analyze organizational effectiveness to assure staff are trained and available at critical times. Frequently test communications networks used to distribute evacuation warnings and other life-saving information. Many areas also have Local Emergency Planning Commissions (LEPCs) available to advise utilities directly on how to make infrastructure and operations more resilient.

Consider Climate Modeling

As weather events increase in severity, climate risk modeling is another modern planning measure that benefits service providers. Engaging a climate trend analysis consultant can provide valuable insights and help you make informed decisions regarding your service area. Predictive analytics reveal when existing infrastructure and physical assets may be at risk in the near and long term. These insights will help determine what, where and when to prioritize climate risk mitigation measures. Climate risk modeling also helps with making a strong business case for system hardening by enabling a cost-benefit analysis of potential preventative investments. Black & Veatch's eBook on climate modeling for utilities explains how to address key factors including location, weather patterns and climate change data.

Case Study: Proactive Texas Utility Protects Customers a Decade After Implementing Winterization Strategies

In February 2021, a powerful storm blanketed Texas with snow and ice. Record low temperatures knocked out power and heat to 4.5 million homes and businesses across the state. More than 200 lives were lost, and property damage amounted to more than $190 billion. New questions arose about confidence in the grid's resiliency. In the western Texas town of El Paso, the situation was significantly different. Out of El Paso Electric's 443,000 customers, less than 3,000 lost power during the polar vortex. Why was this city faring better than the rest of the state?

In 2011, El Paso experienced a traumatic storm which, at the time, was the region's worst weather event in half a century. After life-threatening disruptions to power and water, El Paso Electric decided they would never let this happen to their city again. The utility enlisted Black & Veatch's expertise and spent 18 months winterizing their generation, transmission, and distribution assets. El Paso Electric set a prime example for other utilities by taking system hardening measures to bolster grid integrity. In the event of the next polar blitz, strategic winterization blueprints could keep utilities and their most vulnerable customers from being left out in the cold. Learn more about this project here.

Step 2. Prepare

The planning phase consists of what an organization does on paper to document physical actions to take. During the preparedness phase, plans are executed to ensure that people, equipment, resources and infrastructure are ready before disaster strikes. Although actions in the preparation phase still are considered preventative measures, the time available to implement them may be more limited than during the planning stage. Regardless of missed planning opportunities, preparation efforts still are more affordable than emergency responses and can optimize outage and recovery timelines.

Focus on Low-Cost, High-Impact Strategies

There are cost-effective, high-impact preparation measures such as deploying sandbags to strategically re-route stormwater in flood-prone areas. Monitor the storm's progress and adjust the response as necessary. Prepare field crews for potential rapid deployment and extended work hours.

Coordinate with Other Stakeholders

To protect inhabitants of the service area, it's critical to cooperate with the federal, state and/or local emergency management departments and collaborate to prepare a customized, comprehensive plan. These public safety officials have the authority in all jurisdictions to enforce evacuations, and it's essential for all stakeholders (including other utilities, law enforcement, transit agencies, and local businesses) to follow their instructions in disaster situations. The emergency management department has planned for the worst-case scenario (such as a downed power line over a major road) and developed redundant evacuation routes to get people out of harm's way. Make sure personnel are informed on the latest version of this plan. Prepare a procedure on how to communicate real-time hazard updates and outages with customers and other affected stakeholders.

Step 3. Respond

Much like planning and preparation, response and recoverysometimes are seen as interchangeable, but the distinction in this context is important. Response refers to actions taken during and immediately after a natural disaster, while recovery refers to the more long-term efforts to get a community back on its feet. With aging infrastructure plaguing virtually every service provider, the possibility of failure is looming. The planning and preparedness phases are critical for increasing the resilience of these systems, and those pre-disaster phases should inform response and recovery activities when facing the threat of a system failure.

Prioritize the Three Ps: People, Property and Prevention

Response efforts include protecting people, protecting property, and preventing the situation from escalating. Even if the customer has been evacuated from the service area, the hazards aren't gone. A damage assessment and triage of district assets needs to be completed to identify and immediately address live electrical wires, damaged substations and fallen poles. Damage assessments can be completed by personnel on foot, by vehicle, through remote-enabled technology such as drones, or a combination of these methods. Energy utilities benefit from employing either in-house or external damage assessment professionals that can be mobilized immediately after a natural disaster.

Safely Repair Assets and Restore Services

Restoration of the power grid continues to be important in the response phase. To ensure a complete restoration of operations, deploy crews for repair and replacements as necessary. Conduct adequate testing of repaired equipment and infrastructure before restoring to full operation.

Case Study: Supporting Utilities Through the Biggest Storms of Our Generation

In early 2023, Winter Storm Mara had widespread impacts from Texas to Tennessee – causing more than 150,000 systemwide power outages. A local energy utility hired Bird Electric, a Black & Veatch company, as an outside contractor to augment their ongoing power restoration efforts. The utility historically hadn't needed to request external contractor support, but the unprecedented scale of these outages and post-storm conditions of ice and fallen trees called for special expertise. Bird Electric provided essential equipment and placed more than 1,000 full-time employees in the field. Coordinating a vast number of outside resources resulted in various logistical challenges, but Bird Electric was able to expedite crew onboarding and resource allocation – enabling safe and timely restoration of power for the affected community.

Step 4. Recover

Recovery encompasses long-term and future-focused efforts to restore damaged grid infrastructure and get the community back to“business as usual.” These recovery efforts could take months, years or even decades depending on the severity of the disaster and the region's level of resiliency. Mitigation activities should be considered while conducting recovery efforts, to increase resiliency and ensure that future disasters do not repeat the same damage to infrastructure.

Leverage Applicable Funding

If an organization is eligible, the recovery phase presents an opportunity when federal funding may become of greater interest. The Infrastructure Investment and Jobs Act (IIJA) provides funding for new and existing programs related to storm resiliency and response. Even with billions of dollars on the table, it can be challenging for energy utilities to navigate the funding available for recovery efforts and the complex requirements. Consider working with an expert consultant partner that specializes in getting the most out of federal grant dollars.

Return to Step 1: Continuous Improvement to Break the Cycle of Devastation

The recovery phase builds upon all the previous steps: planning from years prior, preparation from just before the storm, and damages remaining after the initial response. Although recovery is the“final” step in this context, this is actually where the resiliency journey makes a full circle back to the planning phase. Reflecting on lessons learned and continuously improving the resiliency plan is essential to prevent history from repeating itself.

Next Steps: Collaborate with an Expert Advisory Partner to Guide Your Resiliency Journey

Storm-related dangers are only increasing in severity. Half of all U.S. states will be in the top 5% most at-risk locations in the world by 2050. Many grid systems are built upon aging infrastructure and are at risk of catastrophic failure. Many energy utilities haven't been able to make upgrades due to complicated funding qualifications or uncertainty about the best path forward. Fortunately, expert advisory partners are available to help utilities navigate all the complexities of developing a robust and comprehensive storm resiliency strategy.

At the end of the day, the core mission is to ensure uninterrupted power for customers, regardless of the challenges posed by nature. Although all four of these steps -- plan, prepare, respond and recover -- are important, planning cultivates the biggest opportunity to mitigate risk and bolster resiliency. Mapping out resilience before critical infrastructure is even built is ideal. Collaborating with a design-build expert that offers a full suite of engineering, construction, management, funding advisory, and storm readiness services can provide numerous advantages for both new and existing assets. By partnering with a company that offers all these capabilities in-house, providers can benefit from a streamlined process that ensures continuity and consistency throughout the project lifecycle. This approach can help to optimize project outcomes, reduce delays and budget overruns, and ensure that assets are well-equipped to withstand natural disasters and other disruptive events.

How can the authorities prepare for a Saharan dust storm?

Dust storms can cause power outages, reduce visibility, and disrupt air and road transport.

sources and danger.

At the beginning of this year's spring season, the incidence of dust storms increased significantly.
Their frequency varies from year to year, but generally increases in the transitional periods between seasons, especially spring and autumn, for many reasons, some natural and others of a human nature, that is, by man.
Dust storms are fast winds that transport dust and plankton, causing a lack of visibility at short distances.
Despite the great controversy over the causes of dust or dust storms and the fact that the camel bears full responsibility for their occurrence, as stated in one of the videos circulated on social media, the reasons are not limited to the poor camel alone, even if it is one of the reasons!
The causes of dust storms are many, including: (1) Desertification as a result of drought resulting from low rainfall.
(2) Desertification due to human activities associated with overgrazing as a result of increasing numbers of camels and sheep on pasture capacity.
(3) Extensive agricultural activities, especially ploughing the land and leaving it exposed for long periods.
(4) Soil movement as a result of development and military actions and absurd car tracks in deserts that led to the breaking and dismantling of the soil and the destruction of vegetation cover.
(5) The reduction of the surface groundwater table, which led to the drying of the soil and thus the impact on the vegetation cover.
Globally, sub-Saharan Africa is the main contributor to Earth ’ s dust storms, which travel to the Americas via the Atlantic Ocean via tropical east winds.
But the Fertile Crescent has also become a source of dust, due to the halving of agricultural production as a result of climate change.
Iraq is one of the sources of dust storms as a result of the decline of the level of rivers, which led to the drought of the marshes and lakes in Iraq and Iran, and add to the list of sources open deserts of the Kingdom, which suffer environmental degradation as a result of human tampering of unfair grazing and wood and the like.
Dust storms are one of the factors responsible for increased allergic reactions, asthma attacks and chronic breathing problems, as well as blood vessels and heart disease.
Dust storms are also carriers of microorganisms, including bacteria, fungi, germs and viruses that cause certain diseases.
Besides, dust storms have economic effects, they adversely affect agricultural production by transporting agricultural pests, reducing photosynthetic activity, destroying crops, as well as affecting infrastructure, by reducing visibility, disrupting energy and air and road transport systems, burying railways, as well as contributing to the deterioration of the performance of solar panels, as well as damaging residential property.
There is no doubt that dust storms and their increased frequency are a warning sign that requires a rapid response through a review of environmental regulations, the need to raise the environmental awareness of the population, the organization of grazing seasons based on the identification of the pastoral capacity of each region, as well as innovative solutions to mitigate desertification that benefit from tremendous technical progress.
Finally, it follows from the above that the problem is not country-specific, but a regional problem that requires concerted efforts.
The Green Middle East initiative by Prince Mohammed bin Salman is designed to design innovative solutions to address climate change and promote environmental sustainability through a number of projects, including: planting 50 billion trees across the Middle East region and reclaiming 200 million hectares of degraded land through afforestation, which contributes to a 2.5 per cent reduction in global carbon emissions.

Forest fire seasons are already becoming longer and more intense.
In the United States, the area burned has increased dramatically, from about 1.3 million acres in 1983 to more than 7.6 million acres in 2020.
This trend is not limited to the United States and Canada.
In recent years, severe wildfires have ravaged the Amazon, Alaska, Australia, California, Europe, Indonesia, Russia and Turkey, spreading pollution over vast distances.
Rising temperatures and drier conditions due to climate change not only contribute to an increase in forest fires, but are also associated with increased desertification.
Drought and land degradation can intensify sand and dust storms, which together with forest fires carry significant environmental and health risks.
Sand and dust storms are intense, driven by strong winds that carry dust particles from corrosive soils, particularly in degraded and drought-affected areas, due to unsustainable land practices, devegetation and biodiversity loss.
It destroys millions of hectares of renewable natural assets and contributes significantly to air pollution in some parts of the world.
Recent studies reveal that more than 50 percent of the annual average PM2.5 exposure in Central Asia and the South Caucasus can be attributed to natural dust and forest fires.
"Rising temperatures and drier conditions due to climate change are not only contributing to increased wildfires, but are also associated with increased desertification.
"Drought and land degradation can intensify sand and dust storms, which together with wildfires carry significant environmental and health risks."
Air pollution is part of a feedback loop that multiplies climate impacts and air pollution from smoke and dust affects the environment, public health and productivity.
It is part of a feedback loop that multiplies climate impacts, with wildfires being a major source of greenhouse gas emissions and forest destruction, while natural dust storms are associated with soil erosion and carbon loss, as well as low crop yields.
In war-affected Ukraine, wildfires have contributed significantly to the increase in air pollution-related deaths, with about 8 per cent of PM2.5 emissions due to forest fires.
In Uzbekistan, a recent study estimated the economic losses caused by sand and dust storms from the dry floor of the Aral Sea at $44 million annually.
Careful land restoration planning can significantly reduce air pollution and improve health and livelihoods, providing annual benefits of between $28 million and $44 million.

San Antonians may want to stay indoors next week. Here's why.

A noticeable change in the air will arrive to the Alamo City next week.

SAN ANTONIO — San Antonio skies could look quite different next week but not in the way we're hoping for.

As San Antonians eagerly wait for rain to break our triple-digit temperatures another common occurrence will pick-up next week known as Saharan dust.

The dust is a combination of sand and dust traveling from North Africa across the Atlantic that peaking in late June through mid-August.

Light amounts of Saharan dust have arrived to the Alamo City this past week but will become more noticeable. Therefore, if you have asthma, COPD or any other type of respiratory illness you will want to stay indoors as much as possible during this time.

Timing of Saharan dust:

Monday - Little changes will be in the forecast as heavier amounts of dust remain over the gulf coast.

Thursday - As the week progresses dust levels continue to rise and could affect air quality levels. For those with any respiratory illnesses they should avoid outdoor activity including vigorous exercise. Also try to keep windows and doors closed. We will continue to monitor this development next week.

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.

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.

Energy Challenges: Global and Ukrainian Realities, and Ways to Overcome Them, Denys Kostrzhevskyi

Denys Kostrzhevskyi

KYIV, UKRAINE, July 23, 2024 /EINPresswire.com/ -- Power outages in Ukraine are becoming regular due to large-scale attacks on the energy system by Russia. The Economist reported that due to the extensive destruction and lack of funding for rapid recovery, the electricity shortage will remain large, and Ukraine has lost a total of about 90% of its generating capacity.

Global Electricity Situation
Abnormal heat around the world creates additional risks of power outages. According to Bloomberg, hotter summers significantly increase the demand for cooling, as well as increasing the risk of forest fires due to overheating of wires.

‘Unstable supplies and growing consumption may lead to blackouts, as was the case in Montenegro and neighbouring countries. Incidents related to high temperatures also occurred in Ecuador and India, affecting both developed and developing countries’, Denys Kostrzhevskyi, Chairman of the Board of Directors of Kyiv International Airport and Vice President of the European Facilitation Platform (EFP), says.

Impact of Climate Change on Power Grids
Climatic changes increase the vulnerability of power grids to various natural disasters: floods that destroy power transmission towers, droughts that dry up reservoirs, and surges in demand for cooling during heat. According to Bloomberg, the modernisation of power systems to achieve the goal of ‘net zero’ by 2050 will cost approximately USD 24.1 trillion.

‘This includes expanding and upgrading infrastructure that requires replacing outdated poles, wires, transformers, and other power grid components with more climate-resilient ones. An important step is also the use of new technologies, such as smart grids, which allow more efficient management of electricity consumption and distribution, faster detection and repair of damage,’ he continues.

The transition to renewable energy sources is another key area that requires significant investment. Increasing the share of solar and wind energy in the total energy balance requires the creation of new generation facilities and energy storage systems.

‘This will not only reduce dependence on fossil fuels, but also facilitate reduction of greenhouse gas emissions. The development of inter-connectors between different countries and regions is also important for ensuring the stable electricity supply. Inter-connectors make it possible to quickly redirect electricity flows in case of accidents, which increases the reliability of the power system and reduces the risks of outages. These measures are necessary to create a sustainable and reliable energy system that can withstand the challenges of climate change’, Mr Kostrzhevskyi assures.

Situation in Ukraine
Since the beginning of the invasion, Russia has been attacking thermal, hydroelectric, and solar power plants in Ukraine, significantly reducing electricity production.

Last winter, Ukraine managed to partially restore power and survive the winter with fewer interruptions, but this year’s attacks exacerbated the problem again. Those Nuclear power plants that have not been destroyed cannot fully meet the needs of the country. Ukrainians and enterprises have to adapt to new conditions. People buy diesel generators, gas turbines, and batteries.

The energy sector plans to restore several more GW of capacity by winter due to the repair of damaged facilities and the supply of used equipment from Europe.

A long-term solution to the problem of electricity shortages will require significant efforts and time due to the destruction of critical infrastructure and lack of resources.

‘Energy efficiency should become a priority for every household and enterprise in Ukraine. The use of energy-efficient devices and optimisation of consumption will help reduce the load on the power system and reduce the risks of outages’, Denys Kostrzhevskyi believes.

He also thinks that only joint efforts of citizens and authorities can overcome today’s energy-related challenges. Responsible handling of energy resources and active international cooperation will help Ukraine and the world to withstand this difficult period and build a sustainable energy system in the future.
