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.
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 ...
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 ...
The Nama Karoo in South Africa is a xeric shrubland that receives between 100 and 500 millimetres (4 and 20 in) of rain a year. [3]The conversion of productive drylands to desert conditions, known as desertification, can occur from a variety of causes.
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 ...
Most of these areas receive over half their annual precipitation from the monsoon. [3] 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, and helps fuel the Chihuahuan Desert's extreme ...
The average annual temperature in the desert varies from about 13 to 22 °C (55 to 72 °F), depending on elevation and latitude. The mean annual precipitation for the Chihuahuan Desert is 235 mm (9.3 in) with a range of approximately 150–400 mm (6–16 in), although it receives more precipitation than most other warm desert ecoregions.
