Desert regions that typify Barren Lands yield very low vegetative cover due to low annual rainfall, often less than 25 mm per year, and variable distribution of rainfall. In Africa, these systems exist in the Namib and Sahara Deserts, the northern and southern most regions of the continent. The climate of these regions is severe with daytime temperatures reaching as high as 60 °C (140 °F) and night temperatures dropping below freezing. Both deserts receive the majority of their yearly precipitation in the form of winter rains.
