aeolian process
Let an agent explain aeolian processes, relay mechanisms, landforms and impacts from geomorphology and atmospheric science sources, describe the named processes, relay dust storm safety, and distinguish aeolian processes from fluvial, glacial and coastal wave processes and from weathering.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain aeolian processes, relay mechanisms, landforms and impacts from geomorphology and atmospheric science sources, describe the named processes, relay dust storm safety, and distinguish aeolian processes from fluvial, glacial and coastal wave processes and from weathering.
Geomorphological processes driven by wind, including aeolian erosion by deflation and abrasion, aeolian transport of sediment by suspension, saltation and surface creep, and aeolian deposition forming sand dunes, sand sheets and loess, active especially in deserts, coasts and glacial outwash plains, studied systematically since Ralph Bagnold s The Physics of Blown Sand and Desert Dunes of 1941; dust storms from aeolian processes affect air quality, health and transport, and people should follow dust storm warnings.
What it is for: Not applicable; a natural process.
It can be explain mechanisms; relay landforms and impacts; describe named processes; relay dust storm safety.
Distinguishing features
Wind driven
Arid and coastal settings
Dunes and loess
Dust impacts
What it looks like
Moving sand and dust, ripples, dunes and wind-sculpted rocks.
Physical character
Bagnold s book: 1941 year - The Physics of Blown Sand and Desert Dunes
saltation grain size: mainly sand about 0.06-2 mm
loess: wind-blown silt deposits note
How it is recognised
Wind-driven erosion, transport and deposition
Aeolian deposition, aeolian transport, deflation, saltation
Fluvial processes involve rivers; glacial processes involve ice; coastal wave processes involve the sea; weathering breaks rock in place
