  6. 6. DUST STORMS• A dust storm (or sand storm) is a common meteorological phenomenon that is common in. arid and semi-arid regions
  7. 7. The Sahara Desert is a key source of dust storms, particularly the Bodele Depression and an areacovering the confluence ofMuritania, Mali, and Algeria]

  13. 13. DUST STORM LEAVING EGYPT: MAY 13, 2005
  14. 14. 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.
  15. 15. IMPACTS OF DUST• Dust storms can cause or worsen breathing problems.• Finally, dust in the atmosphere can also influence weather and global climate change.
  16. 16. ECONOMIC IMPACTS• Reduced visibility caused by dust can affect aircraft transportation.
  17. 17. 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.
