Description of Sharan Dust Sky
A large dust cloud just crossed the Atlantic Ocean and moved over parts of the eastern U.S. The dust storm formed in early June 2020 over the western Sahara Desert in western Africa. The dust storm started at the ground, but then got pushed up into the atmosphere on vertical currents of air. Once the dust cloud moved up into the atmosphere, it got caught up in the trade winds. Trade winds are winds that continuously blow from east to west in the tropical part of the Atlantic. It took about 24 days to cross the Atlantic and move into the southeast US. The dust created some beautiful sunrises and sunsets.
