tropical rainy climate

A major category (the A climates) in W. Köppen's 1936 climatic classification; in order to be so classified, a climate must have these two characteristics: 1) the mean temperature of the coldest month must be 18°C (64.4°F) or higher, separating it from temperate rainy climates; 2) the annual precipitation must be in excess of a certain amount to distinguish it from dry climates (
see formulas under steppe climate).

The three principal types of climate included in this category are the tropical rain forest climate, tropical savanna climate, and tropical monsoon climate
