DUST STORMS • A dust storm (or sand storm) is a common meteorological phenomenon that is common in. arid and semi-arid regions
The Sahara Desert is a key source of dust storms, particularly the Bodele Depression and an area covering the confluence of Muritania, Mali, and Algeria]
Saharan dust storms have increased approximately 10-fold since the 1950s.
ALGERIAN DUST STORM • This dust storm, like others, carried Saharan dust across the Atlantic Ocean all the way to the Southeast United States.
PAST NOTABLE REGIONAL DUST STORMSUnited Arab Emirates--Feb., 2009Al-Asada, Iraq; April 2005Egypt, May 13, 2005
IMPACTS OF DUST • Dust injects nutrients, such as iron, into marine ecosystems. • Dust also carries bacteria and spores from fungi, which can cause diseases long distances away.
IMPACTS OF DUST • Dust storms can cause or worsen breathing problems. • Finally, dust in the atmosphere can also influence weather and global climate change.
ECONOMIC IMPACTS • Reduced visibility caused by dust can affect aircraft transportation.
ECONOMIC IMPACTS • Dust storms cause soil loss from the dry lands, and the abrasive effect of the storm damages young crop plants. • They preferentially remove organic matter, thereby reducing agricultural productivity.
