Tropical rain forest

From Glossary of Meteorology



tropical rain forest

(Also called equatorial forest, selvas.) A type of rain forest that exists in tropical regions where precipitation is heavy, generally more than 250 cm (98 in.) per year.

It consists mainly of a wide variety of lofty trees, which carry a profusion of parasitic or climbing plants, and, in some portions, a "jungle" of dense undergrowth near the ground. For lack of marked climatic seasons, growth proceeds throughout the year.
Compare temperate rain forest.
