Why is there such high temperature weather in Turpan Basin?

First of all, although Turpan Basin is located in the north of 40 north latitude, in summer, the angle between the midday sun and the ground is quite large. In addition, in summer, the days are long, the sky is clear and partly cloudy, so the solar radiation heat reaching the ground is very large.

Secondly, Turpan basin is deep inland and has obvious continental climate characteristics. The ground heat capacity is small, and the temperature rises sharply after heating, unlike the eastern coastal areas affected by sea breeze, so it is more prone to high temperature weather than the eastern coastal areas under the same heating conditions.

Moreover, the surface of Turpan Basin lacks vegetation and a large number of waters, so the effect of evaporation and transpiration is not obvious.

In addition, the Turpan Basin is relatively closed and the communication between the atmosphere and the outside world is weak, which is easy to cause high temperature in some areas.

Under the comprehensive effect of the above reasons, the temperature in Turpan Basin is very high in summer, making it a "fire state" in China. Turpan basin produces cotton, grapes and fruits. Because of the large temperature difference between day and night, it is beneficial for crops to accumulate nutrients. Therefore, the quality of crops in Turpan basin is good, the fiber of cotton is long and the sugar content of grapes and melons is high. There are many varieties of grapes here, and the most precious one is "seedless white grape", which is sweet and juicy with crystal clear meat. If dried in a cool room, it will turn into translucent emerald raisins. The raisins produced here are well known. It is said that as far back as 1500 years ago, Gao Changguo sent envoys to pay tribute to Turpan raisins in Liang Wudi.
