Sand and dust storms are common meteorological hazards in arid and semi-arid regions. They are usually caused by thunderstorms – or strong pressure gradients associated with cyclones – which increase wind speed over a wide area. Dust storms are also known as Haboob, which is Arabic word for Violent winds.
Shamal is hot and dry, dusty wind from the north or northwest in Iraq, Iran, and the Arabian Peninsula. Simoom is extremely hot and dry local wind in Arabia and the Sahara.
Derecho is a warm-weather phenomenon. It is a widespread, long-lived, straight-line windstorm” that is associated with a “band of rapidly moving showers or thunderstorms”. The name comes from the Spanish word ‘la derecha’ which means ‘straight’. Straight-line storms are those in which thunderstorm winds have no rotation unlike a tornado.
