Tropical rainforests are characterized by a warm and wet climate with no substantial dry season: typically found within 10 degrees north and south of the [[equator]]. Mean monthly temperatures exceed {{convert|18|C|F}} during all months of the year.<ref>Susan Woodward.

Many of the world's [[tropical forests]] are associated with the location of the [[monsoon trough]], also known as the [[Intertropical Convergence Zone]].<ref>Hobgood (2008).

Retrieved on 8 March 2009.</ref> The broader category of [[tropical moist forests]] are located in the [[Equator|equatorial zone]] between the [[Tropic of Cancer]] and [[Tropic of Capricorn]]. Tropical rainforests exist in [[Southeast Asia]] (from [[Burma|Myanmar (Burma)]]) to the [[Philippines]], [[Malaysia]], [[Indonesia]], [[Papua New Guinea]] and [[Sri Lanka]]; also in [[Sub-Saharan Africa]] from the [[Cameroon]] to the [[Democratic Republic of the Congo|Congo]] ([[Congolian forests|Congo Rainforest]]), [[South America]] (e.g. the [[Amazon rainforest]]), [[Central America]] (e.g. [[Bosawás Biosphere Reserve|Bosawás]], the southern [[Yucatán Peninsula]]-[[Petén Department|El Peten]]-[[Belize]]-[[Calakmul Biosphere Reserve|Calakmul]]), [[Australia]], and on [[Pacific Islands]] (such as [[Hawaiian tropical rainforests|Hawai{{okina}}i]]). Tropical forests have been called the "Earth's [[lung]]s", although it is now known that rainforests contribute little net [[oxygen]] addition to the [[Earth's atmosphere|atmosphere]] through [[photosynthesis]].<ref>Broecker, Wallace S.
