West Africa – June 22nd, 2013

Named after the engineer and fluid dynamicist Theodore von Kármán, in fluid dynamics, a Kármán vortex street is a repeating pattern of swirling vortices that are created when the flow of a fluid separates unsteadily as it moves around blunt bodies. Here, this phenomenon can be seen in the upper left quadrant, as spiralled cloud patterns southwest of the Canary Islands. In the lower left quadrant, dust can be seen blowing off the coasts of Mauritania and Senegal.
