Agrotermos

Preferred term

Tormenta de polvo

An unusual and frequently severe weather condition characterized by strong winds and dust-laden air over an extensive area. Prerequisite to a dust storm is a period of drought over an area of normally arable land, thus providing the very fine particles of dust which distinguish it from the more common sandstorm of desert regions. Sand and dust storms (SDS) are natural atmospheric events generated in arid and semiarid regions, usually caused by strong near-surface winds associated with thunderstorms and frontal synoptic conditions. During these weather-driven extreme events, large amounts of particles of a broad range of sizes are uplifted from the soil. Sand and dust distinguish the size of the particles involved in SDS – “sand” refers to coarse particles (with diameters of > 60 micrometres (mm)) and “dust” refers to finer particles (with diameters of < 60 mm, including silt and clay).
