Saharan Dust Storm •

Last update: December 6th, 2019 at 8:00 am

Thick dust blew through the Sahara Desert in late June 2012, extending over parts of Algeria, Mali, Mauritania, and Morocco. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this image on June 23, 2012. The dust plume spanned hundreds of kilometers north to south and east to west.

Sand seas provide ample material for dust storms, and such seas extend across substantial portions of Algeria, Mali, and Mauritania. Sand seas also cover parts of Western Sahara. In addition to sandy desert, this region is covered with impermanent rivers, and the fine sediments of dry riverbeds can also be borne aloft by winds.
