What do you mean by a slight chill? -What's the difference?
Slight cold is the 23rd solar term among the 24 solar terms, the 5th solar term in winter, the end of the second month of the dry calendar and the beginning of the ugly month. The Great Cold is the last of the 24 solar terms. Both are solar terms indicating temperature changes. In most parts of our country, the periods of slight cold and severe cold are generally the coldest, so there is a folk saying that slight cold and severe cold are cold into ice cubes. According to China's long-term meteorological records, there is no slight cold in the great cold solar terms in the northern region; But for most parts of the south, April and September are the coldest, so the big cold solar terms are colder than the small ones.
The difference between mild cold and severe cold
1, after the winter solstice, the direct point of sunlight will gradually move northward, but in the following time, the direct point of sunlight will always be in the southern hemisphere, and the heat in the northern hemisphere will always be lost. The heat absorbed during the day is still less than the heat released at night. Therefore, after the winter solstice, the temperature in the northern hemisphere will continue to decrease, and slight cold and severe cold will become the two coldest solar terms in a year. As the saying goes, "It's 239 when it's cold, and I'm shivering with cold." . This shows the cold degree of the slight cold solar terms.
2. Every year around 65438+10.20, when the sun reaches 300 degrees of the yellow meridian, it is a great cold. The ancients thought that the "day" of alternating cold and summer was to recover quickly after a cold. If you caught a bad cold before the slight cold, and you can't feel "recovered" after the coldest, then put the bad cold behind you and let it return to beginning of spring, which is in line with the way of "extremes meet". There is also a saying that the slight cold in winter corresponds to the "slight heat" in summer, so it is called "slight cold"; The severe cold in winter just corresponds to the "great summer heat" in summer, so it is called "great cold"
