A desert is a landscape or region that receives very little precipitation. Deserts are defined as areas with an average annual precipitation of less than 250 mm (10 in), or as areas where more water is lost by evapotranspiration than falls as precipitation. In the Köppen climate classification system, deserts are classed as BWh (hot desert) or BWk (temperate desert). In the Thornthwaite climate classification system, deserts would be classified as arid megathermal climates. wikipedia
