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.
For a relatively weak North African Monsoon, the opposite is true, with decreased annual precipitation and less vegetation resulting in a phase of the Sahara climate cycle known as the "desert Sahara". [1]
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.
Several methods have been used to define the subtropical climate depending on the climate system used. [ citation needed ] The most well known [ 4 ] is the Trewartha climate classification , which defines a subtropical region as one that has at least eight months with a mean temperature greater than 10 °C (50.0 °F) and at least one month with ...
A hot desert climate tends to have two seasons: a long, hot summer and a shorter, mild winter. Phoenix has four months (June-September) when the historical average high temperature is 100 degrees ...
Southern Africa has a transition to subtropical or temperate climates (green and yellow), and more desert or semi-desert regions, centered on Namibia and Botswana. Sub-Saharan Africa has a wide variety of climate zones or biomes. South Africa and the Democratic Republic of the Congo in particular are considered megadiverse countries. It has a ...
The Judaean Desert, the Dead Sea and the western slopes of the Moab Mountains on the opposite side are rain-shadowed by the Judaean Mountains. [citation needed] The Dasht-i-Lut in Iran is in the rain shadow of the Elburz and Zagros Mountains and is one of the most lifeless areas on Earth.
A Köppen–Geiger climate map showing temperate climates for 1991–2020 The different geographical zones of the world. The temperate zones, in the sense of geographical regions defined by latitude, span from either north or south of the subtropics (north or south of the orange dotted lines, at 35 degrees north or south) to the polar circles.
