Aeolian processes are the erosion, transport and deposition of sediment carried out by wind. Deflation strips loose fine grains from a surface, abrasion and attrition wear and round the grains wind carries, and the same wind builds the sand back up as dunes, sand sheets and windblown loess. Water erodes more material worldwide, but wind dominates where vegetation is sparse and sand is exposed, chiefly deserts and their margins.

Wind is the surface expression of atmospheric circulation; the source page names wind rather than the atmospheric-circulation process entity by name.

Causes
Shaped
The Gobi is a classic cold desert whose dune fields, gravel pavement and loess plumes are aeolian landforms.

Wikimedia FoundationIntroduction, definition and setting
Although water is a much more powerful eroding force than wind, aeolian processes are important in arid environments such as deserts.
Deposition section, process-type
Wind is very effective at separating sand from silt and clay. As a result, there are distinct sandy (erg) and silty (loess) aeolian deposits.
Introduction, alias
Aeolian processes are those processes of erosion, transport, and deposition of sediments that are caused by wind.
