  2. Desert climate - Wikipedia

    en.wikipedia.org/wiki/Desert_climate

    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 ...

    Based on precipitation alone, hyperarid deserts receive less than 25 mm (1 in) of rainfall a year; they have no annual seasonal cycle of precipitation and experience twelve-month periods with no rainfall at all. [32] [33] Arid deserts receive between 25 and 200 mm (1 and 8 in) in a year and semiarid deserts between 200 and 500 mm (8 and 20 in ...

    Over the contiguous United States, total annual precipitation increased at an average rate of 6.1 percent per century since 1900, with the greatest increases within the East North Central climate region (11.6 percent per century) and the South (11.1 percent). Hawaii was the only region to show a decrease (−9.25 percent). [89]

    By the time it reaches the east side of the mountains, little moisture is left to bring to the desert. The rain shadow effect is more pronounced closer to the Sierra Nevada, with yearly precipitation in the Great Basin desert averaging 9 inches (230 mm) in the west and 12 inches (300 mm) inches in the east.

    Climate classification systems such as the Köppen climate classification system use average annual rainfall to help differentiate between differing climate regimes. Most of Australia is semi-arid or desert, making it the world's driest continent (excluding Antarctica).

  9. Tropical desert - Wikipedia

    en.wikipedia.org/wiki/Tropical_desert

    The average annual precipitation in low latitude deserts is less than 250 mm. Relative humidity is very low – only 10% to 30% in interior locations, and even the dewpoints are typically very low, often being well below the freezing mark. Some deserts do not have rainfall all year round, they are located far from the ocean.
