It's winter, which solar term is the coldest, heavy snow or severe cold?

The Great Cold is the last of the twenty-four solar terms, and it is called "Great Cold" when the sun reaches 300 degrees on the yellow meridian around 65438+1October 20th every year. Great cold refers to extremely cold weather.

During the severe cold solar term, the atmospheric circulation is relatively stable, and the adjustment period of circulation is about 20 days. When this circulation is adjusted, there will often be a wide range of rain and snow weather and strong winds to cool down. When the west of 80 degrees east longitude is a long wave ridge and East Asia is a coastal trough, under the influence of northwest wind flow control and constantly supplemented cold air, China will have a sustained low temperature.

In the severe cold season, the average temperature in most parts of southern China is 6℃ to 8℃, which is nearly 65438 0℃ higher than slight cold. The proverb "slight cold and cold, cold into a ball" shows that the great cold solar term is a cold period of the year.
