It rained on the solstice of winter. Is there a saying that winter is very warm?

There is indeed a folk saying that it is warm winter after it rains from winter to Sunday, but this is only for some areas. Because the solar terms from winter to sun are unified, but the east, west, north and south of China span a lot, so the weather and climate in different regions are obviously different, so the saying that it rains from winter to sun and there is a warm winter does not apply to all regions.

The winter solstice is the 22nd solar term in the "24 solar terms", and the solar calendar reaches 270 degrees. Every year, the festival is held on 65438+February 2 1-23 in the Gregorian calendar. The solstice in winter is the extreme point of direct sunlight spreading to the south. On the solstice in winter, the sun shines directly on the Tropic of Capricorn, which is the most inclined to the northern hemisphere and the solar altitude angle is the smallest. In all parts of the northern hemisphere, the days are the shortest and the nights are the longest. The solstice in winter is also the turning point of direct sunlight returning to the north. After this day, it went back, and the direct sunlight began to move northward from the Tropic of Capricorn (23 26' s), and the sunlight in the northern hemisphere (China is located in the northern hemisphere) increased day by day.
