  1. Subtropical deserts center on the tropics of Capricorn and Cancer and include most of the planet's great deserts. Their descending air currents are the result of consistently high atmospheric pressure and generate hot, dry winds that prevent cloud formation. These deserts have high year-round temperatures that increase dramatically in the summer. The absence of cloud cover allows daytime heat to dissipate quickly at night, so the temperature can drop suddenly. In fact, temperatures can dip below freezing on winter nights.
