Sand Storm in Iraq

Sand storms are also known as dust storms.This wind is usually caused by convection currents (which are created by intense heating of the ground), and is usually strong enough to move entire sand dunes. Air is unstable when heated, and this instability in the air will cause the mixture of higher winds in the troposphere with winds in the lower atmosphere, producing strong surface winds.Below are pictures of a very serious sand storm from Iraq.This was on 26 April 2005 but is worth a look, because nature shows us his amazing power.
