  2. Tundra climate - Wikipedia

    en.wikipedia.org/wiki/Tundra_climate

    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 ...

  3. Tundra - Wikipedia

    en.wikipedia.org/wiki/Tundra

    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 , [ 2 ] Alpine , [ 2 ] and Antarctic .

  4. Tundra of North America - Wikipedia

    en.wikipedia.org/wiki/Tundra_of_North_America

    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). This precipitation usually falls in the form of light, fluffy snow.

  5. Alpine tundra - Wikipedia

    en.wikipedia.org/wiki/Alpine_tundra

    Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated harsh climate. As the latitude of a location approaches the poles, the threshold elevation for alpine tundra gets lower until it reaches sea level, and alpine tundra merges with polar tundra .

  6. Köppen climate classification - Wikipedia

    en.wikipedia.org/wiki/Köppen_climate_classification

    The Köppen climate classification system was modified further within the Trewartha climate classification system in 1966 (revised in 1980). The Trewartha system sought to create a more refined middle latitude climate zone, which was one of the criticisms of the Köppen system (the climate group C was too general). [10]: 200–1

  7. Holdridge life zones - Wikipedia

    en.wikipedia.org/wiki/Holdridge_life_zones

    The Holdridge life zones system is a global bioclimatic scheme for the classification of land areas. It was first published by Leslie Holdridge in 1947, and updated in 1967. It is a relatively simple system based on few empirical data, giving objective criteria. [ 1 ]

  8. Montane ecosystems - Wikipedia

    en.wikipedia.org/wiki/Montane_ecosystems

    One of the typical life zones on mountains is the montane forest: at moderate elevations, the rainfall and temperate climate encourages dense forests to grow. Holdridge defines the climate of montane forest as having a biotemperature of between 6 and 12 °C (43 and 54 °F), where biotemperature is the mean temperature considering temperatures ...

  9. Altitudinal zonation - Wikipedia

    en.wikipedia.org/wiki/Altitudinal_zonation

    Heating of solids, sunlight and shade in different altitudinal zones (Northern hemisphere) [5] A variety of environmental factors determines the boundaries of altitudinal zones found on mountains, ranging from direct effects of temperature and precipitation to indirect characteristics of the mountain itself, as well as biological interactions of the species.
