The weather in the north in winter

The north is dry and cold, but the temperature is cold and the south is wet and cold. Although the temperature is not as low as that in the north, it is very cold.

1. In the south, the air contains a lot of water, which is called wet condensation. In the north, the air contains less water, which is called dry freezing. Wet freezing is worse than dry freezing. When the temperature is the same in winter, the greater the humidity, the lower the somatosensory temperature. The humidity in the south is high, because the more moisture in the air, the more heat absorbed from the body surface. So people will feel cold and wet and very uncomfortable. Although the temperature in the north is low, there is little water in the air and it feels dry.

2. There is no heating equipment in the south, and the indoor temperature is below 10 degrees in winter. Moreover, there are heating facilities in the north, but most areas in the north are more comfortable in winter.

So generally speaking, although the temperature is low in the northern winter, the human body feels that the northern winter is actually not so cold.

Extended data

The north and south of China are usually bounded by Qinling Mountains and Huaihe River. The area around Henan is a fuzzy area. It is located in the gap between Qinling Mountain and Huaihe River. In addition, the middle parts of Anhui and Jiangsu provinces are located in the south of Huaihe River and the north of Yangtze River, which makes the division a little unclear. According to the foregoing, the boundary between North China and South China does not follow the provincial boundary. It passed through Shaanxi, Henan, Anhui and Jiangsu, and created Hanzhong (Shaanxi), Xinyang (Henan) and other regions. The division of provincial boundaries is the result of careful consideration.

The Yuan Dynasty established by Mongols and the Ming Dynasty established by Han Chinese established many such dividing lines in an attempt to break the local separatist regime. However, people are used to treating Shaanxi and Henan as northern provinces and Anhui and Jiangsu as southern provinces. In addition, Xinjiang, Tibet and Qinghai are all located in the northern part of the Hengduan Mountains, and the local people's personalities and living habits are also close to those in the north, so they belong to the northern region.

In terms of provinces, the north generally includes Heilongjiang, Jilin, Liaoning, Inner Mongolia, Hebei, Beijing, Tianjin, Shandong, Henan, Shanxi, Shaanxi, Ningxia, Gansu, Qinghai, Xinjiang and Tibet.

South refers to the area south of Huaihe River in Qinling Mountains and east of Qinghai-Tibet Plateau, and often refers to the area south of specific or implied azimuth points. In China, "southern region" generally refers to the vast area south of the Qinling-Huaihe line.
