A semi-arid climate, semi-desert climate, or steppe climate is a dry climate sub-type. It is located on regions that receive precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes.
A steppe is usually covered with grass and shrubs, depending on the season and latitude. The term steppe climate denotes a semi-arid climate, which is encountered in regions too dry to support a forest, but not dry enough to be a desert. [2] [3] Steppes are usually characterized by a semi-arid or continental [citation needed] climate. Extremes ...
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 climate of Africa is a range of climates such as the equatorial climate, the tropical wet and dry climate, the tropical monsoon climate, the semi-arid climate (semi-desert and steppe), the desert climate (hyper-arid and arid), the humid subtropical climate, and the subtropical highland climate. Temperate climates are rare across the ...
A tropical savanna is a grassland biome located in semi-arid to semi-humid climate regions of subtropical and tropical latitudes, with average temperatures remaining at or above 18 °C (64 °F) all year round, and rainfall between 750 millimetres (30 in) and 1,270 millimetres (50 in) a year.
The annual rates of precipitation in Alpine-steppes are very low, with mean ranges falling anywhere between 280 and 300 mm. [3] In addition, upwards to 80% of this falls between the months of May and September, causing the climate to be arid or semi-arid, making the environment much harsher for plant and livestock life.

Semi-arid Niger. A semi-arid desert or a steppe is a version of the arid desert with much more rainfall, vegetation and higher humidity. These regions feature a semi-arid climate and are less extreme than regular deserts. [34] Like arid deserts, temperatures can vary greatly in semi deserts.
The Patagonian Desert, also known as the Patagonian Steppe, is the largest desert in Argentina and is the eighth-largest desert in the world by area, occupying approx. 673,000 square kilometres (260,000 mi 2).
