The tundra climate is a polar climate sub-type located in high latitudes and high mountains. It is classified as ET according to Köppen climate classification. It is a climate which at least one month has an average temperature high enough to melt snow (0 °C or 32 °F), but no month with an average temperature in excess of 10 °C (50 °F). [ 1]
Average summer temperatures range from 37 °F (3 °C) to 60 °F (16 °C). The tundra is very much like a desert in terms of precipitation. Yearly average precipitation varies by region, but generally, there is only about 6–10 inches (150–250 mm) of precipitation per year, and in some regions, it can have up to 20 inches (510 mm).
There are two main seasons, winter and summer, in the polar tundra areas. During the winter it is very cold, dark, and windy with the average temperature around −28 °C (−18 °F), sometimes dipping as low as −50 °C (−58 °F).
Summer in Northern Sweden's Tarfala Valley with its alpine climate. Alpine climate is the average weather for the alpine tundra.The climate becomes colder at high elevations—this characteristic is described by the lapse rate of air: air tends to get colder as it rises, since it expands.
The average precipitation is 4.5 in (110 mm) per season. The tundra classifies as a desert due to low precipitation rates, yet permafrost causes even lower degrees of drainage and evaporation and as a result the ground, lakes and glaciers hold large quantities of fresh water. [28]
Conversely, summer temperatures are very low, with an average high around 10 °C (50 °F). [1] This is too low to sustain trees, and the land is treeless tundra . On the Greenland ice sheet , the temperature is far below freezing throughout the year, [ 3 ] and record high temperatures have peaked only slightly above freezing.
The average July temperature in the southern part of the island is 10–13 °C (50–55 °F). Warm summer days can reach 20–25 °C (68–77 °F). [ 4] The highest temperature recorded was 30.5 °C (86.9 °F) in the Eastern fjords in 1939. Annual average sunshine hours in Reykjavík are around 1300, which is similar to towns in Scotland and ...
The climate of Antarctica is the coldest on Earth. The continent is also extremely dry (it is a desert [ 1] ), averaging 166 mm (6.5 in) of precipitation per year. Snow rarely melts on most parts of the continent, and, after being compressed, becomes the glacier ice that makes up the ice sheet. Weather fronts rarely penetrate far into the ...
