Each summer, a cloud of atmospheric dust acts as a
wall against the monsoonal moisture, and keeps the moisture bottled
up over India and from raining over western India to eastern Africa,
as you can see from the Dust Surface Concentration daily images
from the US Navy NRL/Monterey Aerosol Page at http://www.nrlmry.navy.mil/aerosol/index_frame.html.
However, in July and August 2010, the wall of dust over Pakistan
fell, allowing the monsoonal moisture to fall in torrential rains,
with devistating consequences. Between July 3 and 4, the dust
curtain parted from northern Pakistan, which set the stage for
Also note that the monsoonal moisture caused other
flood events outside of Pakistan: July 13 = KSA torrential rain.
July 10-15 = Yemen and KSA Jeddah flash floods. July 23-25 = KSA
By monitoring the atmospheric dust, the lack of dust
over certain areas, may help predict future flood events. Also,
a positive effect could be, by controlling the atmopheric dust
over these arid regions, may benefit the people living there,
by helping to increase the annual rainfall.
