Abstract

The paper describes the environmental and climatic changes which took place in Africa from the late Pleistocene through the Holocene and the general atmospheric circulation patterns which likely correspond to them. Three major periods are considered: (1) a period of aridity and dune building c. 20,000-12,000 B.P. in which the Sahara advanced considerably southward; (2) a moist, lacustrine period c. 10,000-8,000 B.P.; and (3) a second moist, lacustrine period toward c. 6,500-4,500 B.P. in which the entire Sahara desert contracted considerably. The prevailing atmospheric circulation patterns are theorized on the basis of corresponding changes of surface boundary conditions-primarily changing thermal character—and known dynamic behavior of the atmosphere.
