Simoom or a Terrible Dust Storm

Simoom is a strong, dry, dust-laden local wind that blows in the Sahara, Palestine, Israel, Jordan, Syria, and the deserts of Arabian Peninsula. Its temperature may exceed 54°C (129°F) and the humidity may fall below 10%.
The storm moves in cyclone (circular) form, carrying clouds of dust and sand, and produces on humans and animals a suffocating effect. The name means “poison wind” and is given because the sudden onset of simoom may also cause heat stroke. This is attributed to the fact that the hot wind brings more heat to the body than can be disposed of by the evaporation of perspiration.
