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 the northwest wind and the constantly supplemented cold air, China will have a sustained low temperature. 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. Severe cold is the period with the least rain in a year. During the cold solar term all the year round, the rainfall in most parts of the south only increased slightly compared with the previous period, with 5 ~10mm in most parts of the south and only1~ 5mm in the mountainous areas of the northwest plateau.

During the severe cold season, there is still less farm work in various places.

In the southern region, the field management of wheat and other crops is still strengthened. There is a custom of catching voles in Lingnan area of Guangdong Province in combination with severe cold. Because the crops have been harvested at this time, the nests of voles that are usually invisible are exposed, and the great cold has become an important opportunity for Lingnan to focus on eliminating voles.

The great cold solar term is from March 9 to April 9, and the cold wave frequently goes south, which is the coldest period of the year. As the folk proverb says, "there is no wind and cold when there is a slight cold."

Due to the vast territory of China, the climate between the north and the south is quite different. According to China's long-term meteorological records, there is no slight cold in the great cold solar terms in the northern region; However, for most parts of the south, the big cold solar terms are colder than the small cold solar terms.

As soon as the great cold is over, a new cycle begins, which means that winter goes and spring comes.

For some crops, a proper low temperature is necessary in a certain growth period. Wheat and rape with strong winterness need lower temperature through vernalization stage, otherwise they cannot grow and develop normally. Most of southern China is warm in winter all year round. Wheat and rape sown too early often grow too vigorously, bolting in advance, and their cold resistance is greatly weakened, which makes them vulnerable to low temperature frost. It can be seen that selecting crop varieties according to local conditions, sowing and planting in time and taking effective measures to promote and control are important links to win high yield.

Slight cold and severe cold are the periods with the least rainfall in a year. During the cold solar term all the year round, the rainfall in most parts of the south only increased slightly compared with the previous period, with 5 ~10mm in most parts of the south and only1~ 5mm in the mountainous areas of the northwest plateau. During the winter drought in South China, the water consumption is small, and the contradiction between supply and demand of farmland water is generally not prominent. In the case of scarce rain and snow, it is undoubtedly beneficial to the growth of wheat crops to water in different areas according to different farming habits and conditions.
