The Saharan Air Layer, commonly referred to as Saharan dust, results from ripples in the atmosphere that loft large amounts of sand and dust from the African desert into the air, according to the National Oceanic and Atmospheric Administration. The blanket of dry air and strong winds travels thousands of miles across the Atlantic, creating a less favorable environment for tropical cyclones to form.
Saharan dust is common this time of year. The plumes typically begin in mid-June and run through mid-August, peaking somewhere in the middle. The plumes of dust seem to rapidly subside after mid-August, which is also when Florida begins to see an uptick in tropical activity, according to NOAA.
The dust plume blocks some sunlight from reaching the ocean, which cools it down a bit. The dry air also keeps potential tropical systems from getting the moisture they need to develop.
Will there be ‘Saharan dust sunsets’?
Saharan dust interacts with sunlight to create beautiful sunrises and sunsets.
However, thicker plumes can partially block out the light and lead to hazy skies. A layer of dust may appear as it falls to the surface.
