On the occasion of the winter solstice festival, the question of when there will be a "sloppy year" resurfaces in front of the public. But what kind of scientific secrets are hidden behind this? Through an in-depth study of the meteorological patterns between the winter solstice and the beginning of the year, the National Climate Center has analyzed in detail the precipitation trend during the New Year in February. In the process, people not only show a rich sense of reverence for nature, but also prove that there is some truth in ancient legends such as "the sloppy year of the sunny winter solstice" and "the edge of the bad year of the sunny winter solstice".
Today, the winter solstice has quietly descended on the world. This is the moment when the ecliptic passes 270 degrees, and the sunlight shines directly at 23°26'18.20''' (near the Tropic of Capricorn) at the southern tip of the Earth, announcing the official start of a new cold wave this winter.
At this moment, the central and eastern parts of the continent are shrouded by a strong cold and high pressure, creating a cloudless and sunny winter scene. Those who are early risers may have noticed the blue of the sky, a deep and captivating blue, like Hemingway's autumn sea, layered and cheerful. All this is due to the cold high pressure from the south of the northwest region, its intensity is so violent, like the magnificent scenery of "northern grassland blue"!
Of course, it is important to note that while the sunny weather on the winter solstice is pleasant, it does not necessarily predict that the whole winter will be equally sunny. According to the National Climate Center, the transition in winter weather is mainly influenced by cold air activity, which has a fixed cycle. In other words, almost every few days, cold air hits us, bringing us cold, windy and even snowflakes. The folk saying "the sunny winter solstice is a sloppy year" or "the sunny winter solstice is rotten year" reflects this change.
In addition, the period from the winter solstice to the New Year lasts for about a month, which is precisely the cycle of long-wave changes in the atmosphere. Therefore, if the winter solstice happens to be a cold and sunny day, the chance of rain and snow will be greatly increased at the time of the New Year, and if the winter solstice is warmer and wetter, then the probability of rain and snow will be relatively lower around the New Year.
According to the special situation of this year's winter solstice weather, the cold high pressure dominates the central and eastern parts of the country on the basis of not changing direction, making the thick clouds in the area seem to be dispersed and the sky is as clear as washing. This vibrant scene also gives a celebratory atmosphere, and even when the minimum temperature zero line invades southern cities such as Nanning in Guangxi, Guangzhou in Guangdong, and Fuzhou in Fujian, winter becomes interesting.
At present, the map of the central and eastern parts of the country has shown a trend of less precipitation (yellow area) in the early part of this year, so it is estimated that the possibility of "a sloppy year from a clear winter solstice" is not too large, but the specific prediction needs to be further observed. However, this does not mean that people should let their guard down, as the cycle of long-wave changes in the atmosphere does not run at a uniform speed, and the course of each cycle varies greatly, and many other uncertainties still have an important impact.
Finally, will the weather conditions of this year's winter solstice really confirm the old legend that "the winter solstice is a sloppy year"? Let's wait and see! In short, the sky of the winter solstice reveals irreversible clouds and sunny days, and even more inexhaustible colors. Just like today, despite the cold temperature, the feeling of warm sun brought by the blue sky and white clouds makes people temporarily forget the pain of wind, frost, rain and snow. Only meteorologists can truly understand the mystery behind the "scruffy year of the winter solstice" and witness their shining light on the road of scientific exploration.
On the day of the winter solstice, the sky is clear, the earth is frozen, cold and warm coexist, and hope and challenge go hand in hand. On the earth, people spend this cold winter together, looking forward to the spring garden full of spring and the bright moon and stars of summer night. No matter what the future holds, we must stick to our original intentions, maintain our love, bravely meet the challenges of life, and interpret the meaning of life with actions.
