Like arid deserts, temperatures can vary greatly in semi deserts. They share some characteristics of a true desert and are usually located at the edge of deserts and continental dry areas. They usually receive precipitation from 250 to 500 mm (9.8 to 19.7 in) but this can vary due to evapotranspiration and soil nutrition.
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.

Tropical deserts are located in regions between 15 and 30 degrees latitude. ... Landforms caused by wind erosion vary greatly in characteristics and size.
Certain desert endotherms have evolved very specific and unique characteristics to combat dehydration. Male sandgrouse have specialized belly feathers that are able to trap and carry water. This allows the sandgrouse to provide a source of hydration for their chicks, who do not yet have the ability to fly to water sources themselves. [14]
Errachidia, a desert city in southeast Morocco, recorded nearly 3 inches of rainfall, most of it across just two days last month. That’s more than four times the normal rainfall for the whole ...
