Answer: The berg winds are described as being dry because of extensive heat in South Africa.
Explanation:
When the air that has been heated on the extensive central plateau flows down the escarpment to the coast it undergoes further warming by adiabatic processes. This accounts for the hot and dry properties of these off-shore winds, wherever they occur along South Africa's coastline.
Antarctica is the driest continent; it is almost entirely desert. Very little snow or rain falls on the continent, but because it is so cold, the small amount of precipitation that does fall does not melt.
