  2. Desert climate - Wikipedia

    en.wikipedia.org/wiki/Desert_climate

    To delineate "hot desert climates" from "cold desert climates", a mean annual temperature of 18 °C (64.4 °F) is used as an isotherm so that a location with a BW type climate with the appropriate temperature above this isotherm is classified as "hot arid subtype" (BWh), and a location with the appropriate temperature below the isotherm is ...

  3. Desert - Wikipedia

    en.wikipedia.org/wiki/Desert

    Polar deserts (also seen as "cold deserts") have similar features, except the main form of precipitation is snow rather than rain. Antarctica is the world's largest cold desert (composed of about 98% thick continental ice sheet and 2% barren rock).

  4. Desert ecology - Wikipedia

    en.wikipedia.org/wiki/Desert_ecology

    A desert ecosystem is defined by interactions between organisms, the climate in which they live, and any other non-living influences on the habitat. Deserts are arid regions that are generally associated with warm temperatures; however, cold deserts also exist.

  5. Deserts and xeric shrublands - Wikipedia

    en.wikipedia.org/wiki/Deserts_and_xeric_shrublands

    Many deserts, such as the Sahara, are hot year-round, but others, such as East Asia's Gobi Desert, become quite cold during the winter. [1] Temperature extremes are a characteristic of most deserts. High daytime temperatures give way to cold nights because there is no insulation provided by humidity and cloud cover. The diversity of climatic ...

    en.wikipedia.org/wiki/Biome

    Physiognomy: sometimes referring to the plants' appearance; or the biome's apparent characteristics, outward features, or appearance of ecological communities or species - including plants. Biome: a grouping of terrestrial ecosystems on a given continent that is similar in vegetation structure, physiognomy, features of the environment and ...

    en.wikipedia.org/wiki/Cold_Desert_(biosphere...

    Cold Desert Biosphere Reserve is a biosphere reserve located in the Western Himalayas, within Himachal Pradesh in North India. It was established as a biosphere reserve in August 2009. [ 1 ] Biosphere reserves are the areas of terrestrial and coastal ecosystems which promote the conservation of biodiversity with its sustainable use.

  8. Tundra - Wikipedia

    en.wikipedia.org/wiki/Tundra

    Tundra tends to be windy, with winds often blowing upwards of 50–100 km/h (30–60 mph). However, it is desert-like, with only about 150–250 mm (6–10 in) of precipitation falling per year (the summer is typically the season of maximum precipitation). Although precipitation is light, evaporation is also relatively minimal.

  9. Patagonian Desert - Wikipedia

    en.wikipedia.org/wiki/Patagonian_Desert

    The Patagonian Desert is the largest desert south of the 40° parallel and is a large cold winter desert, where the temperature rarely exceeds 12 °C and averages just 3 °C. The region experiences about seven months of winter and five months of summer. Frost is not uncommon in the desert but, due to the very dry condition year round, snow is rare.
