Slight cold, marking the official start of the season and winter, means that the weather has been cold for a long time, but it has not reached its extreme. The name of the slight cold solar term is explained in the twenty-four solar terms: December solar term, the cold at the beginning of the month is still small, so it is cloudy and half moon. A slight cold means that the weather has been cold for a long time, but it has not reached the extreme. It is related to severe cold, mild summer heat, severe summer heat and treatment.

After the winter solstice, cold air frequently goes south and the temperature continues to drop. During the slight cold and severe cold in a year, the temperature drops to the lowest, and it is 239 in the slight cold, which is enough to explain the degree of slight cold. In the slight cold solar term, the East Asian trough is the strongest and most stable, the Mongolian cold high and Aleutian low are also the strongest and most stable, the ridge scale of the westerly trough is the largest, the westerly intensity is the strongest, and the slight cold solar term.

North-south difference

In the north, the slight cold solar terms are colder than the great cold solar terms, but for most parts of the south, the great cold solar terms are colder than the slight cold solar terms. According to climate statistics, the coldest period of the year in most parts of northern China is in the middle of June 65438+1October, and the slight cold solar term starts from June 65438+1October 5-7, and the solar term is about 15 days, just in the middle. So for most parts of the north, the slight cold is indeed colder than the big cold, but for most parts of the south, it is the coldest in the big cold solar terms.

The slight cold in the north of China is colder than the severe cold, because the surface residual heat is relatively less, which has been released by the slight cold. But at this time, the days are short and the nights are long, and the cold air is powerful, which makes the temperature drop to a minimum, and the light and heat of the sun are slightly increased by the severe cold, so the temperature also rises slightly, while the surface in the south is hot, and the rest solar terms from big heat to slight cold have not been released, so the temperature has not been reduced to a minimum, but in the severe cold, the surface residual heat is exhausted and frozen in the cold, which is slightly higher.
