This circulation is known as the Hadley cell and leads to the formation of the subtropical ridge. [13] Many of the world's deserts are caused by these climatological high-pressure areas, [14] within the subtropics. This regime is known as a semiarid/arid subtropical
A great portion of the world's deserts are located within the subtropics, due to the development of the subtropical ridge. Within the humid monsoon regions in the subtropics such as Northern Vietnam (including Hanoi), a wet season is seen annually during the summer, which is when most of the yearly rainfall falls.
The consistently warm, dry, and sunny conditions of the horse latitudes are the main cause for the existence of the world's major hot deserts, such as the Sahara Desert in Africa, the Arabian and Syrian deserts in the Middle East, the Mojave and Sonoran deserts in the southwestern United States and northern Mexico, all in the Northern ...
Cold deserts, sometimes known as temperate deserts, occur at higher latitudes than hot deserts, and the aridity is caused by the dryness of the air. Some cold deserts are far from the ocean and others are separated by mountain ranges from the sea, and in both cases, there is insufficient moisture in the air to cause much precipitation.
The desert climate or arid climate (in the Köppen climate classification BWh and BWk) is a dry climate sub-type in which there is a severe excess of evaporation over precipitation. The typically bald, rocky, or sandy surfaces in desert climates are dry and hold little moisture, quickly evaporating the already little rainfall they receive.

The Sonoran Desert is clearly distinct from nearby deserts (e.g., the Great Basin, Mojave, and Chihuahuan deserts) because it provides subtropical warmth in winter and two seasons of rainfall (in contrast, for example, to the Mojave's dry summers and cold winters). This creates an extreme contrast between aridity and moisture.
