This chapter reviews the thermal properties and moisture regime of aeolian sand, controls on the growth of vegetation and surface crusts, and the meth

These include ripple migration, grain flow on steeper dune slopes and grainfall in areas between dune crests. Secondary structures also result from processes such as slumping and growth of ice masses.

https://doi.org/10.1007/978-3-663-13668-2The formation of aeolian bedforms is fundamentally dependent on the nature of airflow. This chapter deals with the physical properties of air, the nature and types of air motion at global, regional and local scales, the physical forces which operate in the atmospheric boundary layer, and the interactions between wind and surface terrain.
