Amazon River rain forest in Peru. Tropical rainforests are hot and wet. Mean monthly temperatures exceed 18 °C (64 °F) during all months of the year. [4] Average annual rainfall is no less than 1,680 mm (66 in) and can exceed 10 m (390 in) although it typically lies between 1,750 mm (69 in) and 3,000 mm (120 in). [5]
The tropical rainforest climate differs from other subtypes of tropical climates as it has more kinds of trees due to its precipitation. [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.
A tropical rainforest climate is a tropical climate sub-type usually found within 10 to 15 degrees latitude of the equator. There are some other areas at higher latitudes, such as Bermuda, the coast of southernmost Florida, United States (Fort Lauderdale, West Palm Beach), and Okinawa, Japan that fall into the tropical rainforest climate category.
Tropical climates have an average temperature of 18 °C (64.4 °F) or higher every month of the year, with significant precipitation. [9] [11] Af = Tropical rainforest climate; average precipitation of at least 60 mm (2.4 in) in every month.
About half of the world's tropical rainforests are in the South American countries of Brazil and Peru. Rainforests now cover less than 6% of Earth's land surface. Scientists estimate that more than half of all the world's plant and animal species live in tropical rainforests.
The Hawaiian tropical rainforests are a tropical moist broadleaf forest ecoregion in the Hawaiian Islands. They cover an area of 6,700 km 2 (2,600 sq mi) in the windward lowlands and montane regions of the islands. [1] Coastal mesic forests are found at elevations from sea level to 300 m (980 ft). [2]
A Sapele tree in the Republic of the Congo. The Congolian rainforest is the world's second-largest tropical forest, after the Amazon rainforest.It covers over 500,000,000 acres (2,000,000 km 2) across six countries and contains a quarter of the world's remaining tropical forest.
Borneo rainforest. Some tropical forest types are difficult to categorize. While forests in temperate areas are readily categorized on the basis of tree canopy density, such schemes do not work well in tropical forests. [1] There is no single scheme that defines what a forest is, in tropical regions or elsewhere.
