Where is the temperature difference between day and night? . (in more detail)

The temperature difference between day and night in northwest China is relatively large. For example, Hohhot, Urumqi, Xining and other northwest regions.

Urumqi is the farthest city from the sea in China, with drought and little rain and obvious continental climate. 65438+ 10 monthly average temperature-15.2℃, July-August average temperature 25.7℃. Annual average precipitation194 mm; Spring and autumn are short, winter and summer are long, and the temperature difference between day and night is large.

The average daily temperature in summer in Xining is about 10℃, the highest temperature at noon is 22℃, and the night temperature in summer in July can reach about 2℃. The temperature difference between day and night reaches nearly 30℃.

Extended data:

1. In Xinjiang, the temperature difference between day and night is large, which is mainly related to the ground conditions. The local ground landscape is dominated by desert, with small heat capacity, especially in summer, which absorbs heat quickly during the day, heats up quickly, releases heat quickly at night and cools down quickly.

2. The fundamental reason for the large temperature difference between day and night in Qinghai-Tibet Plateau is the high altitude. The air over the plateau is thin and the content of water vapor and dust is low. During the day, when the solar radiation reaches the plateau, it not only passes through the atmosphere (compared with the plain area), but also is weakened less by the thin gas.

3. Generally speaking, the temperature difference between day and night is larger in inland areas and smaller in coastal areas, because the specific heat capacity of water is greater than that of soil.
