It's another year after a cold! Why is there no slight cold in the great cold?

The Great Cold is the last of the 24 solar terms. At this time, the sun reached 300 degrees of the yellow meridian. The great cold is before the twelfth lunar month, which means that the year will end. Proverbs A slight cold, a year passed? That's what it means. The ancients said: A slight cold is not the coldest time, but a severe cold is the coldest time of the year. So why do we say that there is no slight cold in today's severe cold?

First of all, the Great Cold is the last solar term in a year, which is located at the end of the year. It is not far from the beginning of spring, so the great cold is not necessarily colder than the slight cold, or even warmer. During the severe cold season, farm work is still very rare. In many areas in the north, people are busy accumulating fertilizers and compost to prepare for spring. People also refer to the great cold climate change to predict the rain and grain harvest in the coming year, such as? No wind, no drought and cold? Wait a minute. ?

Secondly, we say that slight cold is the coldest solar term in a year, and we can't just take it literally and think it is no colder than severe cold. The arrival of slight cold marks the arrival of winter, which is the coldest time. Although slight cold? Small? It is the coldest solar term in a year. According to China's meteorological data, only a few years of severe cold temperature is lower than slight cold. China divided the slight cold into three stages; ? Waiting for Yanbei Township, waiting for magpies to nest, waiting for pheasants to nest. ? In this solar term, geese begin to return to the north, magpies start to build nests, and pheasants start to sing. Meteorologically speaking, the slight cold solar terms, the development of East Asia trough is the strongest and most stable, the Mongolian cold high and Aleutian low are also the strongest and most stable, and the ridge scale of the westerly trough is the largest, which matches the strongest westerly intensity. The cooling process of cold air is frequent in slight cold season. ?

Therefore, although the slight cold is small and the great cold is big, it can't be understood literally. In fact, it is indeed colder than the great cold. In this season, we should pay more attention and put on more clothes to prevent colds.
