dessert+climate

The [|desert] is a dry tropical climate. Dry Desert climates are formed by high-pressure zones in which cold air descends. Then the descending air becomes warm but, instead of releasing rain, the heat from the ground evaporates the water before it can come down as rain. The ground is super hot because the sun's rays beat down on it directly overhead. Not a lot of atmosphere to protect it from radiant energy.
 * __Desert Climate:__**

**Here's a couple reasons why some deserts are hot:** 1) Many deserts are largely influenced by something called a subtropical high pressure (described in [|How do deserts form?]). Subtropical refers to it's location, out of the tropics. High pressure is an area of sinking air. As air sinks, it heats up. Not only that, but the warmer air will aid in evaporating water. So, Under a large area of high pressure that rarely moves, there is sinking air which warms the earth and evaporates water from the soil...perfect for a hot desert!       2) Sunlight energy can be used to evaporate water. If there is little to no water to evaporate, then all of that sunlight energy is absorbed by the earth. Then the earth emits more energy into the air thus heating the air even more. 3) The closer a desert is to the equator, the closer it is to the most intense sunshine all year long. The more intense the sunshine, the hotter the land and air will get.
