Dust storm in northern Sudan

A wall of dust rolled across northern Sudan in mid-August, 2015 heading north and east towards Egypt and the Red Sea. The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite captured this true-color image on August 13, 2015.

Strong, sometimes violent, dust storms are common in Sudan. Known as haboobs, they are often the result of the initial downdraft of an approaching thunderstorm, which lifts large amounts of sand and clay from the arid land and drives it in large, rolling sheets across the landscape. The great quantities of sand blown by a haboob can drop visibility to near zero.
