West Africa Dust Storms
|
On the Coast of West Africa, dust storms are a common occurrance, if you take a look at this one, its about the size of Spain. SeaWIFS returned this dramatic close-up view of a vast, developing cloud of Saharan desert dust blowing from northwest Africa a thousand miles or more out over the Atlantic Ocean. Aerosol particles larger than about 1 micrometer in size are produced by windblown dust and other sources. After formation, the aerosols are mixed and transported by atmospheric motions and are primarily removed by cloud and precipitation processes. From space-based vantage points, other satellite images have also revealed storms that transport massive quantities of fine sand and dust across Earth's oceans.
