Every year around 65438+1October 8 (65438+1October 8 ~ 9), when the sun moves to longitude 195 degrees, it is the cold dew of 24 solar terms. "Cold dew" means that the temperature in this period is lower than that in "White dew", and the dew on the ground is colder and will soon condense into frost. According to historical records, "war refers to cold armor as cold dew, and cold is cold and cold, which will condense, hence the name cold dew." Twenty-four solar terms: "September solar terms, dew will condense when it is cold." If the "white dew" solar term marks the change from hot to cold, then the summer heat has not completely disappeared, and crystal dew can still be seen in the morning. Then, the "cold dew" solar term is a symbol of cold weather, which indicates the change from cold to cold, and the dew is cold and radiant. As the saying goes, "Cold dew and cold dew are everywhere in Coody Leng".
According to climatology, after the cold dew, the cold air in the north has a certain influence, and most parts of China are controlled by cold high pressure, and the rainy season is over. The weather is usually warm during the day and cool at night, with clear skies in Wan Li and a scene of late autumn. In normal years, at this time, the isotherm of 10℃ has moved southward to the Qinling Mountains and Huaihe River, and generally falls below 0℃ to the north of the Great Wall. The first frost can be seen in most years in Beijing, the capital. In addition to the perennial snow on the Qinghai-Tibet Plateau, it has generally begun to snow in the northeast and northern Xinjiang. Thunderstorms have disappeared in most parts of mainland China, and thunder can be heard only in parts of Yunnan, Sichuan and Guizhou. The precipitation in June 5438+ 10 in North China is generally only half or less than that in September, while in Northwest China it is only a few millimeters to more than 20 millimeters. Drought and lack of rain often bring difficulties to timely sowing of winter wheat and become one of the main limiting factors for high yield of dry land wheat. In ancient China, the cold dew was divided into three stages: "The first stage was the swan goose; The second waiting sparrow is a clam; Three chrysanthemums have yellow flowers. " In this solar term, geese move south in a line or herringbone queue; In the cold late autumn, all the birds disappeared. The ancients saw a large number of clams suddenly appearing on the seashore. The stripes and colors of shells were very similar to those of birds, and they thought they were birds. The third stage of "Chrysanthemum begins to blossom" means that the chrysanthemum has opened in a large area at this time.
