Submission + - Saharan dust cloud the size of the continental US is impacting summer weather (thehill.com)
fjo3 writes: The Saharan Air Layer, often referred to as Saharan dust, is a 2.5-mile thick “layer cake” that starts about a mile up in the atmosphere, explained Jason Dunion, a University of Miami meteorologist who works closely with NOAA’s Hurricane Research Division.
“They roll off of Africa in the summertime every three to five days, and they’re huge. They’re about the size of the lower 48 states as they cross the Atlantic,” Dunion said.
The Saharan dust season usually peaks between mid-June and mid-August and it’s currently impacting weather around the U.S. in ways you may not have even realized. The layer of warm, dry, dusty air tends to break up the development of thunderstorms and hurricanes.
