Description :
This paper is concerned with characterizing the near-surface airflow upwind of and over partially vegetated linear dunes in the southwest Kalahari Desert. Here are presented measurements of vertical and horizontal wind velocity profiles across cross-sectional transects of 7 partially vegetated linear dunes, with the intention of broadening the understanding of the modificaton of airflow structure caused by the intrusion of a dune into the atmospheric boundary layer. A further aim is to characterize the effect of the partial vegetation cover on airflow over the dunes.
