Why is the air in the south wet and cold?

The reason why there is wet and cold weather in winter in southern China is because the cold air in the north goes south.

The climate in the south is warm. Cold air in the north meets warm air in the south, cold and warm air masses meet, and warm air masses rise to form precipitation. Precipitation is what we usually call rain. After the rain, the humidity in the air increases, the temperature in winter is low and the weather is wet and cold. At the same time, precipitation will also block the sunshine, so the sunshine in wet and cold weather is relatively weak.

The southern region is dominated by tropical and subtropical monsoon climate, with high temperature and rainy summer and mild and little rain in winter. Among them, the tropical monsoon climate is hot all year round, divided into dry season and rainy season. The precipitation is above 800 mm, and there is more precipitation on the windward slope of the mountain. Huoshaoliao in Taiwan Province Province is the "rain pole" of China, with an average annual precipitation of 6558 mm.. The eastern coastal areas are greatly affected by typhoons in summer and autumn.

The temperature is above 0 degrees in winter. Leizhou Peninsula, Yunnan, southern Taiwan Province Province and Hainan are above 15 degrees. Yunnan, Guangdong, Hainan and Taiwan Province provinces are less affected by the cold wave.
