Dust Over Africa - February 27th, 2012

A thick cloud of dust blows over Ethiopia, Kenya, Uganda and South Sudan, obscuring much of the land below. Some dust reaches the green Lake Tana, in Ethiopia, in the upper right quadrant. Parts of South Sudan, near the green Jur River near the image center, are dust free.

A dust storm (also called a sand storm) is a meteorological phenomenon that occurs frequently in arid and semi-arid regions. Dust storms arise when a strong winds blow loose sand and dirt particles off a dry surface. Particles are transported by saltation and suspension, causing soil to move from one place and be deposited in another. The Sahara and drylands around the Arabian peninsula are the main sources of airborne dust.
