Iraq - December 11th, 2011

A cloud of dust appears to be blowing southeastward across Iraq and to the Persian Gulf. The dust hangs in the air over the valley between the Tigris and Euphrates Rivers, obscuring the fertile land below.

Iraq is quite prone to dust storms as it contains many dust source regions, including dried lake beds or wetlands and the deserts in and around the country which contain large amounts of dust. When the winds become strong, particularly above 15 knots (17.3 miles per hour), they begin to pick up the dust. If that wind speed sustains itself for a considerable amount of time, a dust storm is born.
