Dust off West Africa - March 17th, 2012

A plume of dust blows southwestward off the coast of Morocco and over the Atlantic Ocean, passing north of the Canary Islands (click here for previous images).

Visible through the veil of dust are  patterns swirled, roughly symmetrical clouds. This phenomenon is known as cloud vortex streets, or von Karman vortices. They are created by winds rushing over islands in the Atlantic.
