According to FEMA meteorologist Michael Lowry, the intensity of the dust outbreak over the tropical Atlantic was by far the most extreme since the most detailed, continuous record of global dust began in 2002, when the MODIS instruments on NASA’s Aqua and Terra satellites began taking measurements.

Meantime, the first wave of Saharan Air Layer or SAL has arrived. The dusty, stable air mass is limiting thunderstorm activity in the Gulf and Caribbean. By June 28, the dust had thinned so only a few areas in the Midwest, primarily in Kansas, experienced PM2.5 levels in the orange category. Some of these "waves" drift all the way to the Pacific Ocean by crossing Mexico and Central America. It is likely, though, that more African dust outbreaks will counteract this effect in the coming month, since African dust events typically are at their peak in July. On average, 182 million tons of dust leave Africa each year, of which 27 million tons is deposited in the Amazon basin, according to data collected since CALIPSO launched in 2006. The National Weather Service says a SECOND wave of Saharan dust has moved off the coast of North Africa and is making it’s way toward the Caribbean. The AQI was in the orange (unhealthy for sensitive groups) range on that day, and reached the red (unhealthy) range on June 26 and 27 over the Florida Panhandle, much of Texas, and a small portion of Oklahoma.

That iron helps with the orange glow at sunset, but the particles can also cause you to sneeze more often and it also can became food for the red tide algae. Those temperatures ranked as the fourth-highest on record for the region. Dust acts as a shield, keeping sunlight from reaching Earth’s surface. A NASA satellite has been monitoring the movement of sand from the Sahara Desert in Africa to the Amazon rainforest in South America. So grab your tissue and your camera and cross your fingers the red-tide stays away. You can unsubscribe at any time. Subscribe to WDBO newsletter(Opens a new window), The National Weather Service is watching a second wave of Saharan dust moving toward the Caribbean. The cooling may be relatively short-lived, however. Recent satellite imagery shows another strong Saharan Air Layer incursion is underway over the tropical Atlantic, accompanied again by a thick cloud of African dust. Last week’s dust event helped depress sea surface temperatures by 0.4 degrees Celsius in the hurricane main development region of the tropical Atlantic, from the coast of Africa to the Caribbean. Right lane blocked due to accident on FL-528-TOLL Westbound near Exit 13 CR-15 Narcoossee Rd. (See all EOTS posts here. The African dust cloud brought unhealthy levels of PM2.5 to much of the southeastern U.S. beginning on Thursday, June 25, when the air quality index (AQI) exceeded the 24-hour U.S. EPA standard for PM2.5 over the Florida Panhandle region. Saharan dust storm expected to cause dangerous air pollution in U.S. this week. The National Weather Service is watching a second wave of Saharan dust moving toward the Caribbean Photo: National Weather Service. 6/24: GOES-16 satellite imagery shows that Saharan dust moved into the central Gulf. The massive dust storm that formed over the Sahara Desert in mid-June invaded the southeastern U.S. June 25-28, bringing dangerous levels of air pollution, low visibility, and colorful sunsets.

Air pollution has been proven to increase the incidence of deaths caused by strokes, heart attacks, and lung disease. On the flip side, (because - 2020) the dusk can cause harmful algae blooms in Florida due to the large amounts of iron in the soil.

Although it is normal to see SAL outbreaks in June & July, this one is quite significant. According to a 2018 study done by the Health Effects Institute (a U.S. nonprofit corporation funded by EPA and the auto industry), PM2.5 pollution in the U.S. caused approximately 87,000 premature deaths per year between 2010 and 2016. The amount varies each year, however. This is a major reduction in the heat energy available to power hurricanes – a very encouraging development, since ocean temperatures there were 0.6 degrees Celsius above average during the first 25 days of June. A PM2.5 episode as widespread and severe as this – even without the COVID-19 pandemic raging – could cause hundreds of premature deaths. Everything you love about wdbo.com and more!

The dusty, stable air mass is limiting thunderstorm activity in the Gulf and Caribbean. pic.twitter.com/st18BlXxID. Lane blocked due to utility work on US-19 Commercial Way both ways at St Andrews Blvd. A 2019 study, Effects of fossil fuel and total anthropogenic emission removal on public health and climate, found that the health burden of fine particulate matter (PM2.5) air pollution is much higher than had been previously understood. 6/24: GOES-16 satellite imagery shows that Saharan dust moved into the central Gulf. On average, 182 million tons of dust leave Africa each year, of which 27 million tons is deposited in the Amazon basin, according to data collected since CALIPSO launched in 2006. Air pollution deaths are calculated using epidemiological studies, which correlate death rates with air pollution levels. Please check your connection and try again using the Retry button.

After a quick and active start to hurricane season, it looks like any significant tropical development is unlikely over the next week. The National Weather Service says a SECOND wave of Saharan dust has moved off the coast of North Africa and is making it’s way toward the Caribbean. Listen to the most important stories of the day. Of that total, natural sources of outdoor air pollution accounted for 3.24 million deaths per year, and human-caused sources 5.55 million deaths per year. As these causes of death result also from other factors – such as lifestyle and family history – they are usually referred to as premature deaths. pic.twitter.com/gFRppP3ZZH. Meantime, the first wave of Saharan Air Layer or SAL has arrived. Recent forecasts from European and GFS models predict that by the second week of July, surface trade winds in the tropical Atlantic will ease, the result of the Azores-Bermuda High drifting northward and weakening. Dust acts as a shield, keeping sunlight from reaching Earth’s surface. © Cox Media Group. Slower surface winds allow the ocean surface to warm by reducing the amount of cool waters from the depths that are stirred up to the surface, caused by reduced evaporative cooling.

The air pollution event over parts of Texas and the Gulf Coast, composed of fine particulate pollution (PM2.5, particles less than 2.5 microns or 0.0001 inch in diameter) and PM10 (particles less than 10 microns in diameter) was one of the most widespread and intense observed in recent decades.

The space agency’s Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) is tracking the massive plumes of dust particles that make the Atlantic crossing from the great African desert to the largest rainforest in the world, where the particles settle and aid plant growth. The Aerosol Optical Depth (AOD) measured on June 20, 2020, was 1.66, shattering the previous daily record of 1.13 set on July 31, 2013. That study concluded that outdoor air pollution from PM2.5 and ozone causes 8.79 million premature deaths globally each year. Hurricane Sandy, which eventually struck the U.S. east coast as a post-tropical cyclone, also began as a similar tropical wave that formed off the coast of west Africa in October of 2012.
