Hot semi-arid climates characterize the tropics and sub-tropics located in the 20s and 30s latitudes. They are often located near the tropical savanna climate or on the fringe of sub-tropical desert climate. Hot semi-desert climate is known for hot summer and cool winter, with relatively low precipitation.
What are the features of an arid environment?
The defining characteristic of an arid climate is a lack of moisture. The soil is dry, the air is dry, and yearly precipitation is very low. A variety of factors combine to steer storms and moisture away from arid regions. In some arid climates, evaporation rates exceed precipitation, leading to a net moisture loss.
Where are semi-arid climates?
Semi-arid climates include regions like the sagebrush areas of Utah, Montana and Great Basin. They also include areas in Newfoundland, Russia, Europe, Greenland and northern Asia. Semi-arid regions receive more rain, up to 20 inches per year at most, than arid deserts, which receive less than 10 inches per year.
