e. A dust storm, also called a sandstorm, is a meteorological phenomenon common in arid and semi-arid regions. [1] Dust storms arise when a gust front or other strong wind blows loose sand and dirt from a dry surface. Fine particles are transported by saltation and suspension, a process that moves soil from one place and deposits it in another.
Apr 16, 2014 · The first, a dust storm or "sandstorm", is associated with a synoptic scale feature (like a low pressure system). Strong winds along air mass boundaries (i.e. cold front) create clouds of dust as sand, dust, or other particulates become suspended by turbulent eddies near the surface and aloft.

Jul 15, 2021 · Barren ground and sites with low coverage by vegetation (e.g., dunes, soil surfaces, dry lakes, and riverbeds) are the main source areas of sand and dust storms (SDS). The understanding of causes, processes (abrasion, deflation, transport, deposition), and influencing factors of sandy and dusty particles moving by wind both in the boundary layer and in the atmosphere are basic prerequisites to ...

Nov 6, 2020 · Marking the start of the United Nations Decade of Ocean Science for Sustainable Development (2021–2030), this report explores the impacts of sand and dust storms on oceans—their ecosystem functions, goods and services—which are potentially numerous and wide-ranging. Sand and dust storms thus warrant continued careful monitoring and research.
