5 DESCRIPTION OF THE ENVIRONMENT
5.1 Physical Environment
5.1.1 Climate
The climate is classifiable as tropical humid in the highlands that include the areas surrounding Jima and
around the headwaters of the Gojeb River. For the rest, and greatest part, of the watershed the climate is
classifiable as a tropical sub-humid, intermediate between the tropical humid and the hot arid climate
characteristic of the southernmost part of the floodplain toward Lake Turkana. The seasonal variation in
climate is associated with the oscillation of the Inter-Tropical Convergence Zone (ITCZ), a low pressure area
of convergence.
