Temperate climate. In geography, temperate or tepid latitudes of Earth lie between the tropics and the polar regions. These regions generally have more variety in temperature over the course of the year and more distinct changes between seasons compared with tropical climates, where such variations are often more moderate.
A tropical climate in the Köppen climate classification is a non-arid climate in which all twelve months have mean temperatures of at least 18 °C (64 °F). In tropical climates there are often only two seasons: a wet season and a dry season. Tropical climates are frost-free, and changes in the solar angle are small.
(Redirected from Tundra climate) In physical geography, tundra is a type of biome where the tree growth is hindered by low temperatures and short growing seasons. The term tundra comes through Russian тундра (tûndra) from the Kildin Sami word tūndâr "uplands", "treeless mountain tract".
