The transport of sand in saltation is driven by the persistently unsteady stresses exerted by
turbulent winds. Based on coupled high‐frequency observations of wind velocity and sand …

The activity of inland aeolian dune fields is typically related to the external forcing imposed
by climate: active (bare) dunes are associated with windy and/or arid settings, and inactive …

We present an analysis of 10 dune fields to test a model‐derived hypothesis of dune field
activity. The hypothesis suggests that a quantifiable threshold exists for stabilization in …

Barchans are the type of aeolian dune associated with a relatively uniform wind direction,
incomplete sand coverage of the substrate, and low vegetation cover. Here I present an …

The downwind margin of White Sands dune field is an abrupt transition from mobile aeolian
dunes to a dune‐free vegetated surface. This margin is also relatively stable; over the past …
