What is the highest temperature in the desert?

The highest temperature in the desert is 57.7 degrees Celsius.

As follows:

Desert mainly refers to a barren area where the ground is completely covered by sand, where there are very few plants, little rain, and dry air. The desert is also called a "sand curtain", an area with drought, water shortage and few plants. Desert areas are mostly beaches or dunes, and rocks often appear under the sand. Some deserts are salt flats with no vegetation at all. Deserts are generally wind-formed landforms.

There are sometimes valuable mineral deposits in the desert, and many oil reserves have been discovered in modern times. There are few residents in the desert, and resource development is relatively easy. The desert has a dry climate and is also a favorite place for archaeologists, where many human artifacts and earlier fossils can be found. Desert areas have a dry climate and scarce rainfall, with annual precipitation below 250 mm.

The annual precipitation in some desert areas is less than 10 mm (such as the Taklimakan Desert in Xinjiang, China), but there are occasional heavy rains. The amount of evaporation in desert areas is very large, far exceeding the local precipitation; the humidity of the air is low, and the relative humidity can be as low as 5%. The climate varies greatly, with the average annual temperature difference generally exceeding 30 degrees Celsius.

The difference in absolute temperature is often more than 50 degrees; the daily temperature difference changes extremely significantly. In summer and autumn, the near-surface temperature can reach 60 to 80 degrees at noon, but it can drop below 10 degrees at night. Desert areas often have clear skies, cloudless skies and strong winds, with the maximum winds reaching hurricane strength. Causes of tropical deserts: Mainly shrouded by subtropical high pressure, the air sinks and heats up, inhibiting surface convection, making it difficult to cause rain.

If it is blocked by high mountains, located inland, or on the tropical west coast, it can form a desert. For example, the deserts inside the Australian continent are formed because all the water vapor has been lost when the sea breeze arrives. Sometimes deserts form on the lee side of mountains. Ground Material Deserts are not all sandy ground, but more commonly stacked stone ground or rocky ground; there are also lakes and oases on the ground.

Coastal deserts are generally located on the west coast of the continent near the Tropics of Cancer and Tropics of Cancer. Due to the cold current flowing through them, the temperature and humidity are reduced. In winter, there is heavy fog, blocking the sun. The reasons for the formation of coastal deserts are: land influence, marine influence and weather system influence.

The Atacama Desert, a coastal desert in South America, is the driest desert in the world. More than 1 mm of rain often falls only once every 5 to 20 years. The Namib Desert in Africa has many crescent-shaped sand dunes and is often windy.
