What's the date of the great cold? 202 1.

202 1-0 1-20, the Great Cold is the last of the 24 solar terms.

Great cold is an extremely cold season in traditional solar terms. In some parts of China, severe cold is not as cold as slight cold, but in the southern coastal areas of China, the lowest temperature will still appear in the severe cold solar terms.

As soon as the great cold is over, the solar terms of the New Year come again. As the saying goes, winter goes and spring comes. At this time, people are busy getting rid of the old decorations, pickling New Year's dishes, preparing new year's goods and all kinds of sacrificial supplies, and packing things, because the Spring Festival, the most important festival for China people, is coming.

Seasonal characteristics

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 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 within 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. Slight cold and severe cold are the periods with the least rainfall in a year.
