| Term: | Tundra climate |
| Definition: | Generally, the climate that produces tundra vegetation; it is too cold for the growth of trees but does not have a permanent snow-ice cover. In W. Köppen's 1936 climatic classification it is one of the polar climates, defined as having a mean temperature for the warmest month of less than 10C (50F) (in contrast to snow forest and temperate rainy climates) but higher than 0C (32F) (which is the limit of perpetual frost climate). Tundra is designated ET. Tundra climate appears as a temperature province in C. W. Thornthwaite's 1931 classification. |
