  rdf:value "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)."@en ;
