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).

Average precipitation ranges from 20 to 30 cm (8 to 12 in), [43] and the permafrost can be "several hundred meters" thick. [42] Plant species supported by tundra are generally short, lacking stems due to threats posed to vascular structure by frozen temperatures, and much of their growing matter is found below the soil.

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 ...
[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.
The Arctic tundra has historically helped reduce global emissions. But rising temperatures and wildfires in the region are changing that, scientists say. Arctic tundra becoming a source of carbon ...
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 ...
Precipitation is a major component of the water cycle, and is responsible for depositing most of the fresh water on the planet. Approximately 486,000 cubic kilometres (117,000 cu mi) [2] of water falls as precipitation each year; 373,000 cubic kilometres (89,000 cu mi) of it over the oceans. [2]
