Tropical climate

[3] A-group regions are usually found in the tropics, below 23.5 latitude in both the southern and northern hemisphere; they include areas around the Equator, Central America, North-central portions of South America, central Africa, southern portions of Asia and parts of North Australia and the Pacific Ocean islands.

Tropical rainforest climate's Pdry should be greater than or equal 60 mm (2.4 in).

Depending on the location of the region, the wet and dry seasons can have varying duration.

Due to the high temperatures and abundant rainfall, much of the plant life grows throughout the year.

Tropical rainforest vegetation including: Bengal bamboo, bougainvillea, curare, coconut tree, durian and banana.

Tropical monsoon vegetation including: teak, deodar, rosewood, sandalwood and bamboo.

The Köppen classification identifies tropical rainforest climates (Zone Af: f = "feucht", German for moist) as usually having north and south latitudinal ranges of just 5-10 degrees from the equator.

[10] Regions that contain tropical rainforest climate mainly include the upper Amazon basin of South America, the Northern Zaire (Congo) basin of Africa, and the islands of the East Indies.

[12] The large number of trees contribute back to the humidity of the climate because of the transpiration, which is the process of water evaporated from the surface of living plants to the atmosphere.

The warmth and abundant precipitation heavily contributes to the diversity and characteristics of vegetations under the tropical rainforest climate.

[11] The vegetations develop a vertical stratification and various growth forms to receive enough sunlight, which is unusual under other types of climate.

The annual temperature of regions under tropical monsoon climate is also stable.

Typical regions include central Africa, parts of South America, as well as northern and eastern Australia.

[19] Regions under the savanna climate usually have lands covered with flat grassland vegetation with areas of woodlands.
