Yesterday, March 14, a powerful dusty (sandy) storm enveloped and obscured the city of Doha, the capital and the most populous city of the state of Qatar. Fortunately, no information was received about the negative consequences and injuries.
Sand storms occur, as a rule, when the sun heats the sand, which in turn heats the air above it. This causes convection, or “melting” of the air. The movement of air leads to a change in pressure and the appearance of a strong wind, which then picks up and carries sand from the deserts for long distances.
