(a) On an outline map of West Africa, mark and name the (i) approximate position of the ITCZ in January; (ii) low pressure belt in January; (iii) high pressure belt in January; (iv) position and direction of the Tropical Continental A, Mass in January; (v) Guinea current; (vi) Canary current (b) Discuss the relationship between the pressure belts an rainfall distribution in West Africa.
Explanation
(b) There is direct relationship between pressure belts and rainfall distribution in Vest Africa. Pressure belts are created by temperature. When the temperature of a place is very high, it creates a high pressure belt. Wind which carries a lot of moisture therefore blows from a region of high pressure belt to regions of low pressure belts. This therefore results in heavy rainfall in areas of low pressure belts and light rainfall in areas of high pressure belts.
