There are two variations of a desert climate according to the Köppen climate classification: a hot desert climate (BWh), and a cold desert climate (BWk). 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 ...
Desert ecology is the study of interactions between both biotic and abiotic components of desert environments. 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 ...
[a] The all-time lowest recorded temperature in Phoenix was 16 °F (−9 °C) on January 7, 1913, while the coldest daily high temperature ever recorded was 36 °F (2 °C) on December 10, 1898. The longest continuous stretch without a day of frost in Phoenix was nearly eight years, from December 27, 1990, to December 23, 1998. [6]
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.

Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. [1] Deserts are formed by weathering processes as large variations in temperature between day and night strain the rocks, which consequently break in pieces. Although rain ...

The climate of Saudi Arabia is marked by high temperatures during the day and low temperatures at night. The country follows the pattern of the desert climate , with the exception of the southwest, which features a subtropical highland climate and a semi-desert climate .
The cyclic climate pattern of the Sahara is characterized by significant shifts in the strength of the North African Monsoon. When the North African Monsoon is at its strongest, annual precipitation and consequently vegetation in the Sahara region increase, resulting in conditions commonly referred to as the "green Sahara". For a relatively ...
