Agrotermos

Preferred term

sandstorms

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).

sand storms

The term sand storm is used most often in the context of desert sand storms, especially in the Sahara, or places where sand is a more prevalent soil type than dirt or rock, when, in addition to fine particles obscuring visibility, a considerable amount of larger sand particles are blown closer to the surface. Whereas the term dust storm is more likely to be used when finer particles are blown long distances, especially when the dust storm affects urban areas.
