Tundra climate, major climate type of the Köppen classification characterized by sub-freezing mean annual temperatures, large annual temperature ranges (but not as large as in the adjacent continental subarctic climate), and moderately low precipitation. The tundra climate region occurs between 60°.
Tundra winters are long, dark, and cold, with mean temperatures below 0°C for six to 10 months of the year. The temperatures are so cold that there is a layer of permanently frozen ground below the surface, called permafrost. This permafrost is a defining characteristic of the tundra biome.
Tundra climates are the third coldest Köppen climate type on Earth, though extreme subarctic climates (Dfd/Dwd/Dsd) can experience significantly colder winters.
The tundra climate is a transitional climate between the Subarctic and Ice cap climates. It is a region of rolling to nearly level terrain almost entirely devoid of trees. Polar climates like the tundra are characterized by very cold temperatures and generally dry conditions.
The tundra climate, class ET, is found as a nearly unbroken ribbon of land on the Arctic ocean border lands of North America and Eurasia, and along the margins of Greenland. Though nearly exclusive to the Northern Hemisphere, it can be found on peninsular land of Antarctica.
Climate change impact on tundras. The Arctic tundra is changing dramatically due to global warming, a term that falls within a wider range of trends scientists now prefer to call climate...
