  2. Desert - Wikipedia

    en.wikipedia.org/wiki/Desert

    A modern example of desert farming is the Imperial Valley in California, which has high temperatures and average rainfall of just 3 in (76 mm) per year. [121] The economy is heavily based on agriculture and the land is irrigated through a network of canals and pipelines sourced entirely from the Colorado River via the All-American Canal .

  3. Desert climate - Wikipedia

    en.wikipedia.org/wiki/Desert_climate

    The precipitation threshold (in millimetres) involves first multiplying the average annual temperature in °C by 20, then adding 280 if 70% or more of the total precipitation is in the high-sun summer half of the year (April through September in the Northern Hemisphere, or October through March in the Southern), or 140 if 30–70% of the total ...

  4. Desert ecology - Wikipedia

    en.wikipedia.org/wiki/Desert_ecology

    Low levels of humidity in hot deserts contribute to high daytime temperatures, and extensive night time heat loss. The average annual temperature in hot deserts is approximately 20 to 25 °C, however, extreme weather conditions can lead to temperatures ranging from -18 to 49 °C. Rainfall generally occurs, followed by long periods of dryness.

  5. Desert greening - Wikipedia

    en.wikipedia.org/wiki/Desert_greening

    Deserts are regions in which annual precipitation is considerably less than the evaporation, [1] making it difficult for plants and animals that are not specialized to the biome to survive. One of the ways to ensure the success of the plant life is that prior to being planted in the desert, plants are often grown first in greenhouses, allowing ...

  6. Rangeland - Wikipedia

    en.wikipedia.org/wiki/Rangeland

    Desert is a landscape or region that receives an extremely low amount of precipitation, defined as areas with an average annual precipitation of less than 250 millimetres (10 in) per year, [10] [11] or as areas where more water is lost by evapotranspiration than falls as precipitation. [12]

  7. United States rainfall climatology - Wikipedia

    As much as 45% of the annual rainfall across New Mexico occurs during the summer monsoon. [33] Many desert plants are adapted to take advantage of this brief wet season. Because of the monsoons, the Sonoran and Mojave are considered relatively "wet" when ranked among other deserts such as the Sahara. Monsoons play a vital role in managing ...

  8. Chaparral - Wikipedia

    en.wikipedia.org/wiki/Chaparral

    Naturally, desert chaparral experiences less winter rainfall than cismontane chaparral. Plants in this community are characterized by small, hard (sclerophyllic) evergreen (non-deciduous) leaves. Desert chaparral grows above California's desert cactus scrub plant community and below the pinyon-juniper woodland. It is further distinguished from ...

    The Colorado Desert is the low area of the Colorado River Valley and surrounding hills and mountains. Plants must survive its hot and dry conditions. [2]: 7 Temperatures can be greater than 120 °F (49 °C). [2]: 7 Annual precipitation is sometimes less than 3 inches (7.6 cm).
