Tropical Climate
These climates are the ones where the mean monthly temperature remains generally above 22 deg. C. and they occur in the tropical zone. They do not have a perceptible winter season. The major sub types of this type are the tropical rain-forest, tropical monsoon and the tropical savanna climates.
The rain-forest climates are characterized by all the year round precipitation and they support dense evergreen forests of tall trees. The basis of the dense and tall forests is the high temperature and a large amount of precipitation, generally over 250 cms. The climates of the equatorial regions such as Zaire Basin and Amazon are of this type.
