Abstract
Hourly wind speeds at eighteen stations have been used to determine regional and seasonal diurnal and inter-diurnal wind variabilities in southern Africa. From the ratio of the diurnal/inter-diurnal variabilities the degree to which diurnal boundary layer processes dominate the near-ground windfield has been established and mapped in generalised form for the sub-continent at different times of year. Results show the predominance at all times of mesoscale effects over those of synoptic scale in the generation of large-scale atmospheric turbulence in the boundary layer.
