What 2 climates are the most common in Southwest Asia?

The two most common climates in Southwest Asia are arid and semi-arid.

Explanation:

s Southwest Asia, also known as the Middle East, is among the driest regions in the world. This region is dominated by two types of climate, arid and semi-arid. The arid type is commonly refered to as the desert, while the semi-arid is the steppe. The reason why these two climate types are dominant is because of the rain shadow effect from all sides, as well as the air masses not being suitable for creating rainfall.

The deserts tend to be most dominant in the interior of the region. They are very hot, in fact, the world record for highest temperature is recorded here, and they are very dry. The steppes are found around the deserts in general. They tend to have slightly milder temperatures and slightly more rainfall, enough to support small grasses and other highly adapted plants for dry and hot conditions.
