Spring is born and summer is long, autumn is harvested and winter is hidden, and life is lived with the solar terms. Today (October 8) enters the fifth solar term of autumn - cold dew. At this time of the year, the late autumn has arrived in many places in the north, and the forests are dyed, and the autumn in the south is strong, and the chrysanthemum crab is fat. People often feel the beauty of autumn with customs such as climbing, tasting crabs, appreciating chrysanthemums, eating flower cakes, and drinking cold dew tea. China Weather has specially launched the Cold Dew Customs Illustrated Book and the Cold Dew National Weather Map to see how this solar term is passed.
The cold dew has been like this: climb to taste crabs and eat flower cakes to experience the beauty of autumn
During the cold and dew period, the cold air affecting the mainland becomes more active, while the warm and humid airflow gradually declines, and the dry and cold north wind gradually becomes the mainstream. The north wind blew away the summer heat, bringing coolness and a hint of chill, and the autumn front also arrived near the South Ridge, and most of the south of the Yangtze River ushered in autumn. People often feel the beauty of autumn with customs such as climbing, tasting crabs, appreciating chrysanthemums, eating flower cakes, and drinking cold dew tea.
"The autumn wind rises, the crab feet itch, the chrysanthemums bloom, and the crabs smell." In the Jiangnan area, there has been a custom of eating crabs and appreciating chrysanthemums in the cold dew season since ancient times. At this time, the crabs are plump and plump, and the chrysanthemums are in full bloom everywhere, and it is the right time to taste crabs and appreciate chrysanthemums. In some areas, there is also the custom of drinking chrysanthemum wine and chrysanthemum tea.
If tasting crabs and chrysanthemums is an elegant thing in this season, then climbing high and appreciating autumn is a matter of time. In the cold and dew season, the precipitation decreases sharply, and the thick clouds subside, which is suitable for people to climb high and look far. In addition to ascending, since ancient times, there is also the custom of eating flower cakes in the cold dew season, because "high" and "cake" homonym, climbing and eating flower cakes all mean "step by step".
Some places in the south still have the custom of drinking cold dew tea, the tea picked in the first three days and the last four days of the cold dew solar term every year is called "Zhengqiu tea", it is neither fresh and tender like spring tea, nor dry and astringent like summer tea, but has a unique wisp of sweet and mellow fragrance, especially loved by everyone.
The cold dew depends on the weather: the north is getting colder, and the south is getting stronger
"The cool breeze moves, and the cold dew is zero." Cold dew is the first solar term with the word "cold" in the year, and when it enters the cold dew, the temperature also enters a period of rapid decline. At this time of the year, the cooling of various parts of the mainland has entered the fast lane, and many places in the north have transitioned from cool to cold, and the south has bid farewell to the hot autumn.
It can be seen from the national weather map of the perennial cold dew solar term launched by China Weather Network that during the perennial cold and dew solar term, most of the northern part of the mainland has arrived in autumn, and the temperature difference between day and night has increased significantly, especially in the northeast and northwest regions in the transition period of autumn and winter, with frequent cold air activities and strong winds to cool down the weather. At the same time, there are fog disturbances and poor visibility in North China and Huanghuai, so the public should try to minimize going out during the high fog and haze periods, and if you travel by car, pay attention to controlling the distance between vehicles.
In the perennial cold and dew season, the southwest region and other places are in the autumn rainy period in West China, the rain is continuous and lasts for a long time, the southern part of Shaanxi, Sichuan, most of Guizhou, the eastern part of Yunnan, the western part of Hunan, and the western part of Hubei will even exceed the rainfall in this season.
At this time, the intensity of the cold air has strengthened, and the probability of going deep into the south has increased, the summer heat in the south of the Yangtze River has withdrawn, and the autumn is getting stronger. Once the cold air penetrates, it may also cause the southern late rice to appear deflated, empty shell and reduce yield, especially farmers in South China should pay attention to irrigation and heat preservation before the cold dew wind comes, try to avoid the rice field to lose heat, and gradually drain the water after the cold dew wind.
After entering the cold and dew solar term, although the number of tropical cyclone activities will decrease, it is not ruled out that it will affect the mainland, and the coastal areas of South China also need to be vigilant.
"The cold dew frightens the late autumn, and the chrysanthemum turns yellow." In the cold season, the weather gradually turns from cold to cold, and nature also shows obvious changes, late autumn has arrived, and the leaves in the forest will gradually wither after the brilliant flowers. On this cloudy day, let's feel the changes of nature, savor the charm of autumn, and gather strength to prepare for the coming winter.
