Spatial distribution of fog in the Namib
Fog is considered to be one of the most characteristic climatic features of the Namib desert. Despite its importance to desert flora and fauna, relatively little is known about its distribution, especially in the more remote parts of the region. This research note describes the use of Meteosat images for the compilation of annual and seasonal fog distribution maps of the entire Namib. The technique used, as well as the general spatial characteristics of fog as inferred from the maps, are discussed. Comparison between the Meteosat derived annual fog day frequency (FDF) patterns and ground measurements reveals a high level of correspondence. © 1995 Academic Press Limited.
