Great cold welcomes the end of the year! The rebound data of the national average temperature reveals who is the ＂wet and cold king＂ of the Great Cold.

　　China Weather Network News Today (January 20th) is the 29th of the twelfth lunar month, and China has entered the severe cold solar terms. Great cold is the last of the 24 solar terms. "The extreme of cold is called great cold." It means that at this point in the year, the weather is extremely cold. Is the Great Cold really the coldest solar term in a year? China Weather Network takes stock of solar terms big data to see where the great cold is the coldest all year round and who is the "wet cold king" of the great cold.

　　The national average temperature of the great cold solar terms bottomed out and rebounded.

　　"Slight cold and cold, cold into ice balls." Like slight cold, great cold is also a solar term representing cold. Shi Yan, a meteorologist of China Weather Network, said that during the severe cold, most parts of the country entered the winter season, with cold air heading south in the north, frequent snowfall and deep snow in the northeast and Xinjiang. In the south, due to the frequent cold air, rain and snow often disturb, and the feeling of wet and cold is particularly obvious.

　　China Weather Network counted the big data of solar terms from 1991 to 2020, and found that during the slight cold, the national average temperature dropped to the lowest in the whole year, only -5.1℃. In the great cold solar term, the temperature started a rebound journey, which was 0.6℃ higher than the slight cold and reached -4.5℃. As far as the national average temperature is concerned, China’s slight cold solar term is the coldest. Although the severe cold solar term is still frozen and everything is hidden, the temperature has bottomed out and the vitality is lurking, and the pace of spring is getting closer and closer.

　　However, judging from the average temperature in each region, there are also many places where the solar terms reach the lowest in the whole year, such as the coastal areas of East China and South China, northern Xinjiang, and parts of Shandong Peninsula. Generally speaking, there are relatively more areas where the south is cold in the cold.

　　During the Great Cold, the humidity and cold in the south intensified to see who was the "king of humidity and cold" of the Great Cold.

　　The great cold is at the end of the year, and the Spring Festival is often during the great cold. Many friends in the south have the impression of the Spring Festival, that is, they are wrapped in cotton-padded jacket, holding a heater to watch the Spring Festival Gala, and they have to summon up full courage to wash their hair. During the great cold, cold air activities are frequent. At this time, there is enough water vapor in the south, and the warm and humid airflow encounters cold air during the transportation to the north, which often brings a wide range of rain and snow to the south. The magical attack of wet and cold makes people tremble.

　　According to the statistics of China Weather Network, the number of wet and cold days in big cities in the south during the severe cold all the year round, Guiyang ranked first with 4.5 days. Besides the frequent intersection of cold and warm air, Yunnan-Guizhou quasi-static front is also the driving force behind Guiyang’s winning the "king of wet and cold". When cold air goes south, it will form a quasi-static front when it is blocked by Wumeng Mountain, and Guiyang is on the side where cold air accumulates. In winter, it is often "sunny for three days", wet and cold.

　　Changsha, Hefei, Wuhan and Nanchang are also representative cities of wet and cold during the great cold. In winter, the temperature of less than 5℃ or even 0℃, accompanied by days of rain and snow, is as cold inside and outside the house, which are the scenes that these cities often encounter during the great cold. In addition, Nanjing, Hangzhou and Shanghai in the south of the Yangtze River and Chengdu and Chongqing in the southwest are also famous in the wet and cold list.

　　Great cold welcomes the new year, enjoying ice lanterns in the north and visiting flower markets in the south.

　　As the saying goes, "it’s another year after the great cold". The great cold is at the end of the year, and there are many important folk customs. People are busy saying goodbye to the old and welcoming the new year. Among the old customs, the most noteworthy are the ice lanterns in the north and the flower market in the south, one explaining the severe cold in March and the other playing the prelude to spring.

　　Ice lantern, a unique folk art in the north, has a history of more than 100 years in China. It is said that in the past, fishermen along the Songhua River used to freeze an "ice lump" in buckets and light a lamp in the middle for lighting. This is the most primitive ice lamp. Nowadays, many cities in the north will hold ice lantern garden parties during the Chinese New Year. The unique natural ice and snow in the north are skillfully combined with lighting color and voice control to form a fairy tale world of ice and snow art.

　　In many southern areas, it is an essential holiday custom for many families to buy some flowers before the Spring Festival. In Guangzhou, the Spring Festival Flower Market, held three days before New Year’s Eve every year, is the largest and most concentrated market for buying and selling flowers and trees, also known as the Lunar New Year’s Eve Flower Market. The flower market is crowded with people and is very lively. On New Year’s Eve, the flower market entered a climax, with peony, rose, Phalaenopsis, narcissus, wintersweet … … Dozens of flowers compete with each other, adding a warm and vigorous vitality to the festival.

　　"At this point in the world, the winter colors are exhausted, and the spring blossoms soon." Great cold is the end of the twenty-four solar terms, and winter is coming to an end. On the one hand, we can continue to feel the cold in Xiao Su in winter, and on the other hand, we can vaguely feel the signs of spring returns. Everyone will finally get through the long winter and welcome the spring flowers. (Planning/Feng Wei Design/Liu Hongxin Data Support/Shi Yan)
