Why is the temperature higher in summer in the north than in the south?

There are many paddy fields and rivers in the south of China, and the evaporation of water is much greater than that in the north of China. There are many forests, dense vegetation and large transpiration in the south. The south is close to the ocean and the temperature is very high. The evaporation of seawater is unbelievable, and a large amount of water vapor enters the air in the south of China with the south wind.

Therefore, the air in the south contains a lot of water vapor, which is easy to form clouds and lead to rain, so the sky is often covered with thick clouds, and the weather is often rainy, which greatly reduces the actual sunshine time, and sometimes the sun may not be seen for three to five days or more. Although the weather is fine, many water vapor in the clouds and air will obviously absorb and reflect solar radiation, so the temperature will be much milder.

In fact, in summer, according to the intersection of yellow and red, it is gradually warming from March 2 1 to June 22, with seasonal changes from spring to summer, and June to July is the hottest time. Because of latitude, there is also climate and terrain here. The climate in the north is dry and sunny, and the atmosphere has little effect on weakening the solar radiation, while in the south, it is the opposite.

The south is located on the northern edge of the subtropical high. Due to the influence of the static front, it rained for many days and there was no sunshine. However, the north is affected by the mainland high pressure and the weather is very good. The hot sunshine has been following everyone, emitting unacceptable but unacceptable heat every minute, and the temperature will get higher and higher. In July, as the rain belt moves to the northeast of North China, the high temperature in the north will be alleviated, and the Yangtze River basin will enter the summer drought period. When the scorching sun is in the sky, the temperature will rise sharply, and the inversion between north and south will disappear.
