The earliest autumnal equinox this year is coming. Will it be extremely cold this winter?

The autumnal equinox came early this year. At the autumnal equinox, most areas are just cooler than before, and the temperature is not very low, especially at noon. But if the temperature drops sharply today and it is colder than in previous years, then the summer of the next year will be hotter. As we always say, that is to say? It's strange that the autumn equinox is cold and the weather is bad in dog days? . Sure, maybe some places are? The autumnal equinox was surprisingly cold, and the weather was bad on March 9. ? This statement. ?

Rumors that the conclusions accumulated in each region are often not suitable for the whole country. China has a large north-south span and a vast territory. The climate, topography, eating habits and living habits of each region are different. Today, the weather here is just right, neither too cold nor too hot, cloudy in the morning and sunny in the afternoon. I hope it will be warmer in winter and cooler in summer next year. The autumnal equinox is the sixteenth of the twenty-four solar terms, that is, the longitude of the sun 180? About15th day after the Millennium solar term, it is the fourth solar term in autumn, usually in the late September of the Gregorian calendar every year. The autumnal equinox solar terms are the same as the vernal equinox solar terms six months ago. The sun always points directly at the equator, but the autumnal equinox means that the direct point passes through the equator when the sun moves from south to north, while the autumnal equinox means that the direct point of the sun moves through the equator from north to south. Because the sun shines directly on the equator, the geographical phenomenon is the same. During the Spring and Autumn Period, the days and nights around the world were long. ?

However, after the autumnal equinox, the direct point of the sun entered the southern hemisphere, and all parts of the northern hemisphere entered the season of short days and long nights, and polar nights began to appear near the North Pole. When all parts of the southern hemisphere enter the season of long days and short nights, extreme days begin to appear near the South Pole. For China, the autumnal equinox has the significance of climate transition, and the southern part of China may be the real autumn in the meteorological sense after the autumnal equinox and solar terms. So, what's the autumn situation in China this year? Taking Zhejiang Province as an example, Hangzhou officially entered autumn on September 17, obviously earlier than previous years. The meteorological autumn in Hangzhou in recent five years is in the first half of June 10. ?

Let's recall that Zhejiang Province entered the rainy season at the end of May this year, 20 days earlier than in previous years, and now it has entered the autumn ahead of schedule, so it is very likely that it will also enter the winter ahead of schedule this year. From the perspective of climate anomaly, 2020 is a? La Nina? La Nina usually plays an aggravating role, such as more precipitation in rainy season, hotter in high temperature season, less precipitation in dry season or colder in low temperature season. From this point of view, this year's rainy season in the southern region, the precipitation is much higher than the average level in previous years, which is the performance of La Nina phenomenon. So it is possible that it will be cold this winter, too? Winter? . ?

Summary: the number of winter is three or nine, and the number of summer is three volts. March 1949 was the coldest time in winter, the autumnal equinox was surprisingly cold, and the weather was bad in March 1999. It's not surprising that it's cold, and the weather is not bad. The so-called odd is unusual, hot and cold. The so-called bad, it is also very hot and cold, which is different from usual. Of course, with the development of science and technology, weather forecast can predict the weather changes for a long time in the future. Although it is not 100% accurate, it is more convincing than folk proverbs.
