In physical geography, tundra (/ ˈ t ʌ n d r ə, ˈ t ʊ n-/) is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. There are three regions and associated types of tundra: Arctic tundra, [2] alpine tundra, [2] and Antarctic tundra. [3] Tundra vegetation is composed of dwarf shrubs, sedges, grasses ...
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 ...
During the summer the sun shines almost 24 hours a day. Temperatures can get up to 54 °F (12 °C) but it can get as cold as 37 °F (3 °C). 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.
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).
Specifically, this would apply if correcting the average temperature of each month to a sea-level value—using the formula of adding 5.6 °C (10.1 °F) [citation needed] for each 1,000 meters (3,281 ft) of elevation—would cause the climate to fit into a different thermal group from that into which the actual monthly temperatures place it.
Terrestrial ecosystems occupy 55,660,000 mi 2 (144,150,000 km 2), or 28.26% of Earth's surface. [5] Major plant taxa in terrestrial ecosystems are members of the division Magnoliophyta (flowering plants), of which there are about 275,000 species, and the division Pinophyta (conifers), of which there are about 500 species.
The Arctic foothills tundra is an ecoregion of the far north of North America, ... This is permafrost tundra with an average annual temperature below freezing.
Winter temperatures have increased more than summer temperatures. In summer, the daily low temperature has increased more than the daily high temperature. [ 103 ] It has been hypothesised that the boreal environments have only a few states which are stable in the long term - a treeless tundra / steppe , a forest with >75% tree cover and an open ...
