|A FIRST SYNTHESIS OF THE ENVIRONMENTAL, BIOLOGICAL & CULTURAL ASSETS OF THE SOUTPANSBERG|

Sources of information
However, few stations report other meteorological parameters such as temperature, wind speed and direction, evaporation, sunshine/radiation etc.
The general climate of the Soutpansberg should be typed into two seasons only : Warm wet season and cool dry season instead of spring, autumn, winter and summer.
The area receives one cycle of rainfall that extends from October of the previous year and ends in March of the following year (approximately 182 days). The dry season runs from April to October.
Rainfall distribution is greatly influenced by the Soutpansberg. In the middle of the Soutpansberg’s annual rainfall can reach 2 000 mm (Entabeni) and in the western part of the Soutpansberg rainfall can be as low as 340 mm.
Rainfall peaks during January and February.
Wind affects large areas of croplands in semi-arid areas of the Soutpansberg. The prime example is Muswodi area where climatic factors such as rainfall, ambient humidity and drought are associated with it. The area experiences wind erosion during dry months. The erosion is intense in August.
The WWS is associated with convective clouds that occur due to both intense insulation because of the prevailing sun in the southern hemisphere, and also due to the orographic lifting of moist air over the Soutpansberg.
The CDS is mainly associated with clear skies except on top of the high ground where cloud, fog or mist are common, especially during the morning, before the sun is intense enough to dissolve the clouds.
Influence of the Soutpansberg on Rainfall and Wind
All these different forms of effects of orography on rainfall and wind create diverse micro-climates in the study area and result in diversity of fauna and flora.
Major studies and publications
On Climate the area specifically hasn’t received much attention, however, the few works that I have knowledge of include:
