May 28, 2009 - Dust over Cape Verde
Tweet
Dust plumes blew off the west coast of Africa and over Cape Verde on May 23, 2009. The MODIS on the Aqua satellite captured this image the same day.
Camel-colored plumes from the Sahara Desert blow toward the southwest, with the larger plume stretching across Cape Verde. Another plume blows off the coast of Senegal and neighboring countries to the south. Given the wide distance between these plumes, they may have originated from different sources, or wind directions may have shifted since the dust storm started. The red dots you see in the lower right corner mark the location of active fires.
In the west, dust mingles with clouds. Southwest of Cape Verde are Von Karman vortices—repeating swirls in the clouds caused by air currents encountering obstacles, in this case, the islands of the archipelago.
