A tropical climate is a climate typically found within the Tropics, while a few locations outside the Tropics are considered to have a tropical climate. In the Köppen climate classification it is a non-arid climate in which all twelve months have mean temperatures of at least . Unlike the extra-tropics, where there are strong variations in day length and temperature, with season, tropical temperature remains relatively constant throughout the year and seasonal variations are dominated by precipitation. == Subtypes == Within the tropical climate zone there are distinct varieties based on precipitation: * Tropical rainforest climate (''Af''): All twelve months have average precipitation of at least . These climates usually occur within 5–10° latitude of the equator. In some eastern-coast areas, they may extend to as much as 25° away from the equator. This climate is dominated by the Doldrums Low Pressure System all year round, and therefore has no natural seasons * *Examples: * * *Apia, Samoa * * *West Palm Beach, United States * * *Fort Lauderdale, United States * * *Bogor, Indonesia * * *Cebu, Philippines * * *Innisfail, Australia * * *Klang, Malaysia * * *Kuching, Malaysia * * *Mbandaka, DR Congo * * *Paramaribo, Suriname * * *Quibdó, Colombia * * *Ratnapura, Sri Lanka * * *Singapore * Tropical monsoon climate (''Am''):〔 This type of climate, most common in south and Central America, results from the monsoon winds which change direction according to the seasons. This climate has a driest month (which nearly always occurs at or soon after the "winter" solstice for that side of the equator) with rainfall less than 60 mm, but more than (100 − (annual precipitation /25 )). * *Examples: * * *Abidjan, Ivory Coast * * *Cairns, Queensland, Australia * * *Chittagong, Bangladesh * * *Guanare, Portuguesa, Venezuela * * *Huế, Thừa Thiên–Huế, Vietnam * * *Jakarta, Indonesia * * *Macapá, Brazil * * *Miami, United States * * *Puerto Ayacucho, Amazonas, Venezuela * * *Sinop, Mato Grosso, Brazil * * *Yangon, Myanmar * Tropical wet and dry or savanna climate (''Aw''):〔 These climates generally have a pronounced dry season, with the driest month having precipitation less than 60 mm and also less than (100 − (annual precipitation /25 )). * * Examples: * * *Barquisimeto, Venezuela * * * Cartagena, Colombia * * * Ciudad Guayana, Venezuela * * * Dar es Salaam, Tanzania * * * Darwin, Northern Territory, Australia * * * Dili, East Timor * * * Fortaleza, Ceará, Brazil * * * Ho Chi Minh City, Vietnam * * * Honolulu, Hawaii, United States〔(【引用サイトリンク】 work = physicalgeography.net )〕 * * * Jijoca de Jericoacora, Ceará, Brazil * * * Kaohsiung, Taiwan * * * Kupang, Indonesia * * * Lagos, Lagos State, Nigeria * * * Medellín, Colombia * * * Mumbai, Maharashtra, India * * * Naples, Florida, United States * * * Fort Myers, Florida, United States * * * Port-au-Prince, Haiti * * * Rio de Janeiro, Rio de Janeiro, Brazil * * * Valencia, Venezuela * * * Veracruz, Veracruz, Mexico Note that, in this scheme, many places within the tropics do not have a tropical climate: for example, the Sahara Desert. Mountaintops within the tropics, e.g. Mount Kenya, can be cold. However, like lowlands in the tropics (and unlike cold winter temperate zone regions), there is little seasonal variation of temperature in alpine regions of the tropics. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tropical climate」の詳細全文を読む スポンサード リンク
