What are the climatic characteristics of tropical deserts?

Tropical desert climate is characterized by abundant sunshine, strong sunshine, dry heat in summer, large temperature difference between day and night, and many sandstorms.

Because of the dry weather, less clouds and more rain, more sunshine and strong sunshine, there are no clouds in the sky, which leads to some sunshine being blocked, resulting in no water on the ground and no evaporation to cool down. The heat from the sun to the ground is used to heat the earth and the air, so the temperature in summer is particularly high, and the temperature difference between day and night is particularly large.

The four seasons in the desert are quite different from other places at the same latitude. Due to the monsoon climate in eastern China, spring and autumn are very short. However, in desert areas, spring and autumn are shorter. Because the desert area is too dry, there is no water regulation. The temperature rises linearly in spring and falls in autumn. The total temperature in spring and autumn is only about two and a half months to three months.

Extended data;

It is mainly distributed on the west side of the continent at about 20 north latitude and 20 south latitude. It's hot in summer and not cold in winter. Because this area has been controlled by subtropical high for a long time, downdraft prevails, atmospheric stratification is stable, and its west coast is often affected by cold ocean currents, which increases the stability of the atmosphere and inhibits the development of convection, so precipitation is scarce.

Because precipitation is far less than evaporation, water can't make ends meet for a long time, forming a dry desert climate. Such as the Sahara Desert, Western Australia and Peru.

The tropical desert climate is mainly distributed on the north and south sides of the savanna, mainly including the Sahara Desert in Africa and kalahari desert, the Arabian Desert in West Asia, the Western Australian Desert in Oceania, the California Desert in North America and the Atacama Desert in South America.
