Why is West Africa dry?
The first, is the hot, dry tropical continental air mass of the northern high pressure system, which gives rise to the dry, dusty, Harmattan winds which blow from the Sahara over most of West Africa from November to February; the maximum southern extension of this air mass occurs in January between latitudes 5° and 7°N …
Is West Africa humid?
West Africa has wet and dry seasons resulting from the interaction of two migrating air masses. … The second, is the moisture-laden, tropical maritime or equatorial air mass which produces southwest winds. The maximum northern penetration of this wet air mass is in July between latitudes 18° and 21°N.
What time of the year is dry in Western Africa?

What is the environment like in West Africa?
West Africa has a rich natural resource base that includes soil, forest, rangeland, and freshwater and marine resources. Increased pressure on these resources from the rapidly growing population is compounded by the region’s vulnerability to climate shocks such as recurrent drought and rising sea levels.
