What's the difference between the weather in the south and in the north?

The temperature difference between north and south of China is obvious, and the temperature between north and south is naturally different under different climatic conditions. The reasons for the large temperature difference between north and south in China are as follows:

China North-South Temperature Difference: How much is the difference in rainfall?

The south is flooded and the north is dry. China belongs to the East Asian monsoon climate, and the annual precipitation decreases from the southeast coast to the northwest inland. In the south, not only the rainy season lasts for a long time, but also floods often occur because of the concentrated precipitation in summer and autumn. However, the precipitation in North China and Northwest China is relatively low, coupled with excessive reclamation and grazing, and the ability of water storage and drought resistance is poor, so it faces a serious "water shortage", which affects the production and life of local people.

The reasons for the temperature difference between north and south in China are: low latitude in the south and high latitude in the north.

Our country has a vast territory. The distance between north and south is far, geographically speaking, it is lower in the south and higher in the north, with a difference of more than 30 degrees. In the northern hemisphere, the sun shines directly into the southern hemisphere in winter, which leads to stronger or longer solar radiation intensity and sunshine duration and higher temperature in the south than in the north. This is due to the latitude position. Different latitude positions lead to different solar radiation.

The reason for the large temperature difference between north and south in China is that the northern region is close to the cold air pressure.

In the north, affected by the cold high pressure in Mongolia and Siberia in winter, cold air often goes south to form a cold wave, which greatly reduces the temperature. The south is affected by the warm and humid air flow from the ocean, and the winter is mostly mild. This is caused by the climate. The north is close to the source of winter wind, which is greatly influenced by winter wind, and the temperature drops sharply, which intensifies the cold in the north; The south is far away from the source of the winter wind and is blocked by many mountains, especially the east-west mountains. When it reaches the south, it is weak or can no longer affect the south, and the temperature in the south is high.

Causes of temperature difference between north and south in China: topographic factors

East-west mountain ranges, such as the Qinling Mountains, prevent the cold air mass from moving southward, making the temperature in the south high and the temperature in the north low, which naturally increases the temperature difference. This is due to the terrain.
