which region experience very low rainfall and extreme temperature
Answers
Answer:
The typically bald, rocky, or sandy surfaces in desert climates hold little moisture and evaporate the little rainfall they receive. Covering 14.2% of earth's land area, hot deserts are the most common type of climate on earth after polar climate.
Explanation:
Although no part of Earth is known for certain to be absolutely rainless, in the Atacama Desert in northern Chile, the average annual rainfall over a period of 17 years was only 5 millimetres (0.20 in). Some locations in the Sahara Desert such as Kufra, Libya record only 0.86 mm (0.034 in) of rainfall annually. The official weather station in Death Valley, United States reports 60 mm (2.4 in) annually, but in a 40-month period between 1931 and 1934 a total of 16 mm (0.63 in) of rainfall was measured.
There are two variations of a desert climate: a hot desert climate (BWh), and a cold desert climate (BWk). To delineate "hot desert climates" from "cold desert climates", there are three widely used isotherms: most commonly a mean annual temperature of 18 °C (64.4 °F), or sometimes a mean temperature of 0 or −3 °C (32.0 or 26.6 °F) in the coldest month, so that a location with a BW type climate with the appropriate temperature above whichever isotherm is being used is classified as "hot arid" (BWh), and a location with the appropriate temperature below the given isotherm is classified as "cold arid" (BWk).
Most desert and arid climates receive between 25 and 200 mm (1 and 8 in) of rainfall annually.[3] In the Köppen classification system, a climate will be classed as arid if its mean annual precipitation in millimeters is less than ten times its defined precipitation threshold, and it will be classed as a desert if its mean annual precipitation is less than five times this threshold. The precipitation threshold is twice its mean annual temperature in degrees Celsius, plus a constant to represent the distribution of its rainfall throughout the year. This constant is 0 for regions that receive 70% or more of their rainfall during the six winter (colder) months, 28 for regions that receive such a share of rainfall during the six summer months, and 14 for those in-between.[1]
