Dust plumes blew off the west coast of Africa and over the
Atlantic Ocean on December 28, 2012. The Moderate Resolution
Imaging Spectroradiometer (MODIS)
on NASA’s Terra satellite captured this natural-color image the same day.
Multiple plumes blew westward, some arising near the coast, and some arising
east of the Western Sahara-Mauritania border.
Sandy desert extends over parts of Western Sahara and most of
Mauritania. Hot, dust-choked sirocco winds
rank among the leading natural hazards of both countries, according to the CIA
World Factbook. The winds often arise during the winter and spring.
