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 .
West of 100°W, much of the U.S. has a cold semi-arid climate in the interior upper western states (Idaho to the Dakotas), to warm to hot desert and semi-arid climates in the southwestern U.S. East of 100°W, the climate is humid continental in northern areas (locations roughly above 40°N, Northern Plains, Midwest, Great Lakes, New England ...

BWk = Cold desert climate; BSh = Hot semi-arid climate; BSk = Cold semi-arid climate; Group C: Temperate climates. This type of climate has the coldest month averaging between 0 °C (32 °F) (or −3 °C (27 °F)) and 18 °C (64.4 °F) and at least one month averaging above 10 °C (50 °F).
Apr 30, 2018 · What Is a Semi-Arid Climate? Regions with semi-arid climates represent the second driest climates in the world after deserts, known for their dry, arid climates. Semi-arid climates typically receive up to twice the amount of rain than desert regions do -- up to 20 inches per year. Semi-arid climates break down into two distinct classifications ...

3.3 Defining Semi-Arid Regions 3.3.1 Moisture Balance Over the Year as a Whole For definition of semi-arid zones on a regional basis, it is necessary to stipulate lower limits of moisture adequacy which delimit the semi-arid zone from the arid, and upper limits of moisture adequacy that delimit the semi-arid zone
May 13, 2015 · This study analyzes areal changes and regional climate variations in global semi-arid regions over 61 years (1948–2008) and investigates the dynamics of global semi-arid climate change. The results reveal that the largest expansion of drylands has occurred in semi-arid regions since the early 1960s. This expansion of semi-arid regions accounts for more than half of the total dryland ...
Mar 13, 2020 · The regions of the world where average precipitation is between one fifth and half of the potential plant water demand are termed ‘semi-arid’. They make up 15.2% of the global land surface, and the approximately 1.1 billion people who live there are among the world’s poorest. The inter-annual variability of rainfall in semi-arid regions is exceptionally high, due to intrinsic features of ...
