Sand Storm in Dammam Road
A dust storm or sand storm is a meteorological
phenomenon common in arid and semi-arid regions. Dust storms
arise when a gust front or other strong wind blows loose sand and dirt from a dry surface.
Particles are transported by saltation and suspension, a
process that moves soil from one place and deposits it in another.

A sandstorm can transport
and carry large volumes of sand unexpectedly. Dust storms can carry large
amounts of dust, with the leading edge being composed of wall of thick dust as
much as 1.6 km (0.99 mi) high.
Dust storms have also been
shown to increase the spread of disease across the globe. Virus spores in the
ground are blown into the atmosphere by the storms with the minute particles
then acting like urban smog or acid rain.
Dust storms cause soil
loss from the dry lands, and worse, they preferentially remove organic matter
and the nutrient-rich lightest particles, thereby reducing agricultural
productivity. Also the abrasive effect of the storm damages young crop plants.
Dust storms also reduced visibility affecting aircraft and road transportation.
In addition dust storms also create problems due to complications of breathing
in dust.
