Desert climate

Desert climate or Arid climate (in the Köppen climate classification: BWh "hot desert climate" and BWk "cold desert climate") is a type of climate where precipitation is generally less than 250 millimetres (10 in) a year.^[1] Low rainfall is a feature of deserts such as the Arabian, central Australia and the Sahara. It is a feature of continental interiors, the western sides of continents, and the leeward side of tall mountain ranges.^[1] Parts of the Arctic and Antarctic have arid climates even though they are cold.^[1]
