How cold is slight cold and severe cold? Which is cold?

1, the slight cold solar term is colder than the great cold solar term.

2, the slight cold solar terms began. Slight cold indicates the degree of cold. Winter in south China is warm, and the lowest temperature is around-10℃. Only very young people may have a low temperature below 0℃. In addition, the inversion effect is very significant, and the lowest temperature in northern South China is rarely below MINUS 5℃, and the low temperature below 0℃ in southern South China is even rarer. During the slight cold solar term, people should pay attention to the forecast of strong cold air by meteorological stations, guard against the influence of strong winds, rain and snow on Spring Festival travel rush, and pay attention to cold prevention and freezing prevention.

3. During the severe cold solar term, the atmospheric circulation is relatively stable, and the circulation adjustment period is about 20 days. This cycle. During the adjustment period, large-scale rain and snow weather and strong winds often occur. In some parts of China, severe cold is not as cold as slight cold, but in some years and a few coastal areas, the lowest temperature in the whole year 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. Slight cold and severe cold are the periods with the least rainfall in a year, and all the year round is a severe cold solar term. The rainfall in most parts of South China only increased slightly compared with the previous period, with 5 ~10mm in most parts of South China and only1~ 5mm in the mountainous areas of 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.
