The fifth round of large-scale cold wave is coming this winter. How will the temperatures in various places change?

Low outdoor temperature is a natural law. The human body feels cold. The low indoor temperature is mostly caused by humans, and people's feelings are in their hearts. There is an old saying: "The northwest wind blows the grass and rots, and the sun becomes colder." The day is the shortest, and only the golden plum blossoms can be seen in full bloom. ? Will this year be a mild winter or a cold winter? This year's winter solstice falls on December 21st, and November 18th of the lunar calendar is the longest night. After the winter solstice, the days become longer and the nights become shorter. Therefore, the old saying goes: "One Yang is born". Winter Solstice is a festival at home and abroad, but the name is different. Therefore, this day is very important. In ancient times, there was a saying that the winter solstice marked the end of the year. In other words, the Winter Solstice was the Lunar New Year before ancient times.

You see, the solar calendar of the lunar year is not fixed every year, and changes greatly, but the winter solstice is relatively fixed, almost always between December 21st and 23rd. It has never changed, in ancient times the festival was the same as it is now. Holidays are "trouble", good times are holidays, failure is "trouble". So, when the festival comes, everyone says "congratulations" and the disaster is over! On the day of the winter solstice, we eat dumplings in the north, dumplings in the south, and glutinous rice cakes and mutton soup in some areas. However, in addition to enjoying the food on this day, as a farmer, it is also the weather. The weather on this day also heralds the arrival of next year. There is an old saying: "The winter solstice is in the head, and the old cow froze to death. The winter solstice is in the middle, the winter solstice is in the middle, the winter solstice is in the middle of winter." It will be very cold; if the winter solstice occurs in the middle of the winter month, the weather will be warmer, and it will be a Warm winter. In fact, in previous years, we would not be too cold before the winter solstice because the temperature of the earth has not yet dropped. After the winter solstice, the temperature drops significantly. ?Since December 16, most areas in central and eastern China have cooled by 6-10℃. Among them, the temperature drop in southeastern Jilin, southern Shandong, eastern Anhui, most of Jiangsu, and most of Zhejiang can reach up to 12°C or more. However, this cold wave weather will not bring snow to the north. Instead, the temperature will drop and there will be rain in the south, but it will be short-lived and will pass soon.
