Distribution of Winter Temperature in China
The distribution law of winter temperature in China is as follows:
The south is warm and the north is cold;
After winter, the temperature difference between north and south in China is obvious. The lowest temperature in the south is generally around 10℃, and the lowest temperature in the north may be below -20℃. This is mainly because the south is close to the equator and receives more solar radiation, while the north is far away and receives less solar radiation.
In addition, due to the rotation and revolution of the earth, the seasons in the southern hemisphere and the northern hemisphere are opposite, which is one of the reasons why the south is warm and the north is cold.
The temperature difference in the eastern region is small, but the temperature difference in the western region is large;
The temperature difference between the east and the west of China is also obvious. Due to the influence of the ocean, the winter climate in the eastern region is relatively mild, while the temperature in the western region is quite different because of its high terrain and complex terrain. In some high altitude areas, such as the Qinghai-Tibet Plateau, the winter temperature may even be lower than -20℃, while in some low altitude areas, such as Hainan Island, the winter temperature may be higher than 20℃.
General cooling in the country:
After winter, most areas in China will experience obvious cooling process. This is due to the influence of Siberian cold air southward, which led to a period of low temperature weather in most parts of China. In the northern region, because the influence of cold air is more obvious, the cooling rate may be greater. In the southern region, due to the great influence of the ocean, the cooling rate may be relatively small.
Generally speaking, the winter temperature distribution in China is characterized by warm in the south and cold in the north, small temperature difference in the east and large temperature difference in the west. In addition, after entering winter, there will be an obvious cooling process in most parts of China. These laws are of great significance for us to understand the climate characteristics of our country and do a good job in cold prevention and warmth preservation.
