ABSTRACT

The People’s Republic of the Congo has a forest type Guinean climate characterized by higher precipitation and temperatures during the months of October through April. Weather variations throughout the year are affected mainly by the movement of air masses surrounding the country. Two centers of high pressure, the Saharan and South-African, are formed as a result of dry and warm air masses moving, in general, toward the west (see Figure 4.1). A high pressure center originating in the Atlantic (the Saint Helena), carries moist warm air north and eastward onto the continent between the two other high pressure centers. The contact of these air masses produces the Northern and Southern Intertropical fronts. In between these, a monsoon front is formed by the contact of the Atlantic air, and air coming from the Indian Ocean, which is equally warm but dried in part by its passage over the continent from east to west.
