What are the advantages and disadvantages of desert climate?

The air in desert areas is relatively dry, with little or no rain all year round. The daily temperature changes sharply, and the daily amplitude can reach more than 50℃.

Except for a few oases with irrigation conditions, only a few drought-tolerant plants can survive in most desert areas, such as cacti and conifers, which are almost extinct and even become quicksand or desert.

There are also fewer animals, and the most familiar is the camel in the desert. Therefore, especially in the early days, transportation was underdeveloped, and camels were the most commonly used means of transportation. Because of the long-term drought and water shortage in the desert, crossing the desert is particularly dangerous, and it is not easy to cross the desert on foot now.

Desert climate can be roughly divided into tropical desert climate, mid-latitude desert climate and Sahara desert climate.

tropical desert climate

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.

Mid-latitude desert climate

Mainly distributed in the hinterland of the central mainland. This kind of area is far away from the ocean, and the humid airflow is difficult to reach, forming an extremely continental climate: hot in summer, cold in winter, and the daily and annual temperature differences are almost the largest in the world, with little or no rain all year round.

Sahara desert climate

The Sahara Desert is the largest desert in the world, located in northern Africa, with an area of over 9 million square kilometers. The climate of the Sahara desert is controlled by the north-south transition of the trade winds, and there are often many extreme weather. It has the highest evaporation rate in the world, and has the largest area record of no rain for several years. At high altitude, the temperature can reach frost and freezing, while at low altitude, the hottest weather in the world can be found.

But the desert climate is also quite useless.

The particularity of general desert climate leads to the accumulation of different mineral resources.

Most deserts are rich in oil or mineral resources.

And as far as the whole earth is concerned, deserts, like forests, play a decisive role in regulating the climate of the whole earth.

Existence is reasonable.
