The desert climate or arid climate (in the Köppen climate classification BWh and BWk) is a dry climate sub-type in which there is a severe excess of evaporation over precipitation. The typically bald, rocky, or sandy surfaces in desert climates are dry and hold little moisture, quickly evaporating the already little rainfall they receive.

Cold Desert Biosphere Reserve is a biosphere reserve located in the Western Himalayas, within Himachal Pradesh in North India. It was established as a biosphere reserve in August 2009. [ 1 ] Biosphere reserves are the areas of terrestrial and coastal ecosystems which promote the conservation of biodiversity with its sustainable use.
A subarctic climate has little precipitation, [21] and monthly temperatures which are above 10 °C (50 °F) for one to three months of the year, with permafrost in large parts of the area due to the cold winters. Winters within subarctic climates usually include up to six months of temperatures averaging below 0 °C (32 °F).
If the annual precipitation is less than 50% of this threshold, the classification is BW (arid: desert climate); if it is in the range of 50%–100% of the threshold, the classification is BS (semi-arid: steppe climate). [9] [11] A third letter can be included to indicate temperature.
Cold deserts, sometimes known as temperate deserts, occur at higher latitudes than hot deserts, and the aridity is caused by the dryness of the air. Some cold deserts are far from the ocean and others are separated by mountain ranges from the sea, and in both cases, there is insufficient moisture in the air to cause much precipitation.
Yakhchāl of Moayedi, Iran. A yakhchāl (Persian: یخچال "ice pit"; yakh meaning "ice" and chāl meaning "pit") is an ancient type of ice house, which also made ice.They are primarily found in the Dasht-e Lut and Dasht-e-Kavir deserts, whose climates range from cold (BWk) to hot (BWh) desert regions.
The harsh climate of most desert regions is a major obstacle in conducting research into these ecosystems. In the environments requiring special adaptations to survive, it is often difficult or even impossible for researchers to spend extended periods of time investigating the ecology of such regions.
