Perhaps the best example can be seen right now as a massive Sahara dust storm is currently sweeping a cloud of dust across the Atlantic and likely to have a positive impact on both the Caribbean region and the far Southeastern United States coastline including the Gulf of Mexico as far west as Texas. The Caribbean has already received it and parts should be impacting the United States in initial stages right now. This particular dust storm was first identified by the National Aeronautics and Space Administration (NASA) with its SuomiNPP satellite, a joint venture with the National Oceanic and Atmospheric Administration (NOAA). The satellite's Ozone Mapping and Profiler Suite (OPMS), when overlaid over visible imagery data with the Visible Infrared Imaging Radiometer Suite (VIIMRS), can measure dust using aerosol index measurements. In layman's terms, the system from the sky can determine how much dust is in the atmosphere and the impact it likely has on changing water content and storms in the atmosphere. In operation since 2013, it is showing tentative impact of dust on hurricane development and that data supports existing meteorologist concepts that the dust, which usually represents dry air (or it wouldn't be dust), can play a big role in limiting storm development. This, of course, would be good news for those who reside along the coast.
The current dust storm should generate beautiful sunsets and sunrises in the impacted areas and will deliver many nutrients to the rain forest region of Brazil and increase nourishment of beaches in the Caribbean as millions of tons of minute sand particles are dropped on this broad area each year. On the negative side, however, with its high iron content, it can generate red tide formation in the Gulf of Mexico as well. But the current bottom line estimate of what storms like this can do if they are significant enough can potentially provide a major tool in breaking apart hurricanes crossing the Atlantic with their influx of dry, dusty air. Now I'm not saying to jump up and cheer when you hear of large dust storms sweeping westward from Africa, but I am saying that maybe they can give us a little more information to determine what is likely to happen when a storm is coming our way. NASA and NOAA have much more work to do to come to scientific conclusions of what they fully do, but this is a great start. In the meantime, if you are in the impacted areas, enjoy some beautiful and colorful sunrises and sunsets. Be aware, however, if you have serious respiratory issues, the air can have a negative impact. Each of us must use our own free will to decide what is right for us.
Remember, God deserves all the Glory for His Creation, but we are blessed that He has allowed these brilliant and dedicated men of science to develop tools that can give us better information in planning our lives in a time of the year when we worry about hurricanes. His grace is given to those who use the talents they have been give by His plan for them. Wouldn't it be wonderful if those who use their smarts to develop evil schemes instead were made to see the light of their ways. They, too, could do so much good for mankind instead. Let's all pray that a change of heart for them will be a future outcome and it will add even more talent to what needs to be done in the world of modern life. Have a great day.
it can measure aerosol aerAnd while they can have some impact on folks with breathing problems, the principal impacts are largely positive. These storms are not rare, in fact, they often occur during the summer months if the Sahara basin remains dry and trade winds blow steadily out of the east toward and across the Atlantic. The variation between the cool and dry desert earth when beneath a layer of much cooler air can create updrafts which such millions of tons of sandy dust upward from the desert where they come in contact with the heavy summer tradewinds sweeping westward. The dust is then carried west up to five thousand miles across the Atlantic, frequently impacting South America, the Caribbean, and even the entire coastal region of the Gulf of Mexico and the southern portion of that Atlantic coast in the United States. The prime season for this activity is June and July, but it can continue into the heart of hurricane season in late summer and have a potentially dramatic impact on hurricane development.
