How many days is it cold?

The Great Cold is the last of the 24 solar terms.

"Great cold is the middle, and the upper form is slight cold, so it is called Great Cold ... extremely cold, so it is called Great Cold." At this time, the cold wave frequently goes south, which is the coldest period of the year in most parts of China. 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. During this period, railway, post and telecommunications, petroleum, shipping and other departments should pay special attention to take measures to prevent severe weather such as strong winds and blizzards as soon as possible. Agriculture should strengthen the cold and antifreeze of livestock and wintering crops.

During the severe cold solar term, the atmospheric circulation is relatively stable, and the adjustment period of circulation is about 20 days. This cycle

Meridian research

During the adjustment period, large-scale rain and snow weather and strong winds often occur. 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. Therefore, it is necessary to continue to do a good job in the cold protection of crops, especially to protect livestock from wintering.

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 terms are also the cold period of the year.
