Dust Storm over Central and Northern Sudan
A large dust storm covers northern to central Sudan, from the bare deserts of the North to where the land merges into dry grasslands and savanna.
The sand almost reaches the border with Egypt, although as can be seen in the full image, the skies over Egypt were clear at the time the image was captured.
Near Khartoum, the capital, air currents give the dust a spiral shape. Khartoum is prone to dust storms, particularly in the summer, called haboobs.
A haboob is a type of intense sandstorm commonly observed in the Sahara desert (typically Sudan), as well as across the Arabian Peninsula, throughout Kuwait, and in the most arid regions of Iraq.
African haboobs result from the northward summer shift of the intertropical front into North Africa, bringing moisture from the Gulf of Guinea.
