Borneo, with the typical vegetation of tropical forests. Amazon rainforest, Manaus, Brazil. Tropical rainforests have a type of tropical climate (with an average temperature of at least 18 C or 64.4 F in their coldest month) in which there is no dry season—all months have an average precipitation value of at least 60 mm (2.4 in).
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.
In order to be defined as a rainforest, the forest must average at least 140 cm (55 in) of precipitation annually and a temperate rainforest as opposed to a tropical rainforest is defined by a mean annual temperature between 4 and 12 degrees Celsius (39 and 54 degrees Fahrenheit).
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.
While there are locations that fit into all three of the Köppen tropical types of climate, Af, Am, and Aw, the differences among the three climates in Peru are small. The true tropical rainforest (Af) climate requires at least 60 mm (2.4 in) precipitation in all months of the year.
The tropical rainforest climate is characterized by hot and high humidity climate along with heavy rainfall mostly present in the jungles of the Catatumbo, the Amazon river basin the central region of the Magdalena River, the Pacific coast, the paru and others.
Tropical seasonal forests, also known as moist deciduous, monsoon or semi-evergreen (mixed) seasonal forests, have a monsoon or wet savannah climates (as in the Köppen climate classification): receiving high overall rainfall with a warm summer wet season and (often) a cooler winter dry season. Some trees in these forests drop some or all of ...
