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 ...
Coastal deserts are cooler than hot and semiarid deserts, with average summer temperatures ranging between 13 and 24 °C. They also feature higher total rainfall values. Cold deserts are similar in temperature to coastal deserts, however, they receive more annual precipitation in the form of snowfall. [1]
If the area's annual precipitation in millimeters is less than the threshold but more than half or 50% the threshold, it is classified as a BS (steppe, semi-desert, or semi-arid climate). [2] Furthermore, to delineate hot semi-arid climates from cold semi-arid climates, a mean annual temperature of 18 °C (64.4 °F) is used as an isotherm.
Surface temperature of Antarctica in winter and summer from the European Centre for Medium-Range Weather Forecasts. The climate of Antarctica is the coldest on Earth.The continent is also extremely dry (it is a desert [1]), averaging 166 mm (6.5 in) of precipitation per year.
Above 2,000 meters (6,562 ft), temperatures drop as low as an average yearly range between 8 and 12 °C (46.4 and 53.6 °F) in the Cordillera Neovolcánica. At 2,300 meters (7,546 ft), Mexico City (primarily subtropical highland climate) has a yearly median temperature of 15 °C (59 °F) with pleasant summers and mild winters. The city's daily ...
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 .
The North African town of Ouargla, Algeria, which is located in the Sahara Desert, just experienced temperatures of 124 F, or 51 C, which may be the highest ever recorded on the continent.
By contrast most of the Peruvian coastal desert has average annual temperatures of less than 20 °C (68 °F) and with temperatures falling to or near 10 °C (50 °F) during the Southern Hemisphere's winter. [2] [1] The relatively low temperatures of the Peruvian coastal desert are caused by the cold Humboldt Current.
