Characteristics of severe cold solar terms

The climatic characteristics of the great cold solar terms are rain, snow, strong wind and low temperature. At this time, the cold wave moves southward frequently, which is the coldest period in some 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. At this time, the cold wave frequently goes south, which is the cold 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.

After the great cold, like the slight cold, the great cold is also a solar term indicating the 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. 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.

Great cold is the coldest of the 24 solar terms, and most parts of the north have entered the severe winter. In ancient China, the Great Cold was divided into three stages: "One stage is chicken milk; Second, the symptoms of bird disease; Three times, the water is strong. " Among them, the third period can especially show that the temperature of the great cold is extremely low: at this time, the ice in the water can freeze to the center of the water, and it is thick and firm. Judging from these records, it seems that the Great Cold should be colder than the Minor Cold. But in fact, because it is close to spring, it may not be as cold as before.

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. In some parts of China, severe cold is not as good as mild cold, but in some years and a few coastal areas, the annual minimum temperature will still appear in the severe cold solar terms. Therefore, in the cold season, it is necessary to do a good job in cold protection of crops and pay attention to protecting livestock for the winter.
