The tundra climate is a polar climate sub-type located in high latitudes and high mountains. It is classified as ET according to the Köppen climate classification . It is a climate which at least one month has an average temperature high enough to melt snow (0 °C [32 °F]), but no month with an average temperature in excess of 10 °C (50 °F ...
Monthly precipitation totals over most of the Arctic Basin average about 15 mm (0.59 in) from November through May, and rise to 20 to 30 mm (0.79 to 1.18 in) in July, August, and September. [6] The dry winters result from the low frequency of cyclones in the region during that time, and the region's distance from warm open water that could ...
[26]: 51 The cold climate of the alpine tundra is caused by the low air temperatures, and is similar to polar climate. Alpine tundra is generally better drained than arctic soils. [7] Alpine tundra transitions to subalpine forests below the tree line; stunted forests occurring at the forest-tundra ecotone (the treeline) are known as Krummholz.
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).

The climate of the ecoregion is Tundra climate (Köppen climate classification ET), a local climate in which at least one month has an average temperature high enough to melt snow (0 °C (32 °F)), but no month with an average temperature in excess of 10 °C (50 °F). [7] [8]
The last nine years in the Arctic have all had the highest average temperatures recorded since 1900. That dynamic is the result of a phenomenon called Arctic amplification.
The Arctic is rapidly changing from the climate crisis, with no "new normal," scientists warn. Wildfires and permafrost thaw are making the tundra emit more carbon than it absorbs. From beaver ...
