What is the solar term behind slight cold?

1, slight cold is followed by great cold solar terms.

2. The Great Cold is the last solar term among the 24 solar terms, and it is called "Great Cold" when the sun reaches 300 degrees on October 20th at around 65438+/kloc-0. Great cold refers to extremely cold weather.

At this time, the cold wave moves southward frequently, which is the coldest period in most parts of China in a year. The wind is strong, the temperature is low, and the snow on the ground does not melt, showing a cold scene of ice and snow. The Great Cold is the last of the 24 solar terms in China. After the great cold, a new year's solar cycle is ushered in.

4. During the severe cold solar term, the atmospheric circulation is relatively stable, and the circulation adjustment period 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. Like slight cold, great cold is also a solar term indicating the degree of cold weather. Modern meteorological observation records show that in some areas of China, severe cold is not as good as slight cold, but in some years and a few coastal areas, the annual minimum temperature will still appear in the severe cold solar terms.
