Regions with hot semi-arid climates Semi-arid climate in Queensland, Australia. Hot semi-arid climates (type "BSh") tend to be located from the high teens to mid-30s latitudes of the tropics and subtropics, typically in proximity to regions with a tropical savanna climate or a humid subtropical climate. These climates tend to have hot, or ...
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.
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.
The southern part is drier, mostly a savanna climate (Köppen Aw) with small locations on the southern coast dry enough to have a hot-semi arid climate (Koppen BSh). The U.S. Virgin Islands have a tropical savanna climate, with warm, dry winters, and rainy summers (Köppen Aw), typical of the Caribbean. The wet season is from May to October.
Climate zones of Africa, showing the ecological break between the Sahara Desert (red), the hot semi-arid climate of the Sahel (orange) and the tropical climate of Central and Western Africa (blue). Southern Africa has a transition to subtropical and temperate climates (green and yellow), and more desert or semi-arid regions, centered on Namibia ...
The Northern Plains' climate is semi-arid and is prone to drought, annually receiving between 16 and 32 inches (410 and 810 mm) of precipitation, and average annual snowfall ranging between 15 and 30 inches (380 and 760 mm), with the greatest snowfall amounts occurring in the Texas panhandle and areas near the border with New Mexico.
However Wladimir Köppen has distinguished the hot or subtropical and tropical (semi-)arid climates (BWh or BSh) having an average annual temperature greater than or equal to 18 °C (64.4 °F) from the cold or temperate (semi-)arid climates (BWk or BSk) whose annual temperature average is lower. [3]
A semi-arid steppe climate (hot semi-arid climate) predominates over a long stretch of land south of Tropic of Cancer and east of the Western Ghats and the Cardamom Hills. The region, which includes Karnataka , inland Tamil Nadu , western Andhra Pradesh , and central Maharashtra , gets between 400 and 750 millimetres (15.7 and 29.5 in) annually.
