There are two types of tropical climates: the tropical rainforest climate and the savannah climate. Both of these have high temperatures throughout the year. The tropical climate is wet all year round, whereas the savannah climate features a wet and a dry season. The differences between the wet and dry seasons are caused by the Sun’s movement throughout the seasons, which shifts the Intertropical Convergence Zone (ITCZ). The amount and timing of rainfall has a big influence on the landscape.
