Köppen's climate classification includes several tropical (A) climate subtypes: Af (tropical rainforest, no dry season), Am (tropical monsoon, short dry season), and Aw (tropical savanna, pronounced dry winter). Australia's tropical north, due to its more limited landmass extent and rainfall regime, largely lacks the extensive, continuous, high year-round rainfall needed for true Af climate, unlike the vast Amazon basin in South America, which hosts one of the world's largest continuous Af (tropical rainforest) climate zones.
