Abstract

An analysis is undertaken of the temporal variability of climatic parameters that influence dunefield aeolian activity. Data from 7 meteorological stations in the southwestern Kalahari Desert are used, spanning the period 1960-1992. Erosivity is considered through analysis of wind data, and erodibility through analysis of precipitation and potential evapotranspiration, which together influence dune surface plant growth. The data are integrated using Lancaster's mobility index which provides a measure of potential dune surface sand transport
