A desert is a region of land that is very dry because it receives low amounts of precipitation (usually in the form of rain, but it may be snow, mist or fog), often has little coverage by plants, and in which streams dry up unless they are supplied by water from outside the area. [9]
The Thal desert is a subtropical sandy region with severe climatic conditions that are prone to temperature extremes. [17] Approximately 50% of the region sees hyper-arid climatic conditions (annual rainfall less than 200mm) and the remaining half sees semi-arid climatic conditions (annual rainfall between 200mm and 500mm). [18]
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 ...
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.
Cholistan's climate is characterized as an arid and semi-arid Tropical desert, [9] with very low annual humidity. [10] The mean temperature in Cholistan is 28.33 °C (82.99 °F), with the hottest month being July with a mean temperature of 38.5 °C (101.3 °F). [9]
But as climate change makes heat waves more frequent, intense and long-lasting, experts say the increasingly severe conditions are testing some iconic desert plants known for their resilience ...
Rain forests are characterized by high rainfall, with definitions setting minimum normal annual rainfall between 1,750 and 2,000 mm (69 and 79 in). [98] A tropical savanna is a grassland biome located in semi-arid to semi-humid climate regions of subtropical and tropical latitudes, with rainfall between 750 and 1,270 mm (30 and 50 in) a year.
The Central Asian northern desert is an ecoregion in the deserts and xeric shrublands biome, located in the Central Asian countries of Kazakhstan and Uzbekistan.The annual precipitation ranges from 100 to 150 mm (4 to 6 in), the winters are cold at −10 to −15 °C (14 to 5 °F) and the summers hot at around 25 °C (77 °F).
