This year marks the earliest autumnal equinox. Will there be extremely cold weather this winter?

The autumnal equinox came early this year. During the autumnal equinox, most areas are just cooler than the previous period, and the temperature is not very low. It is still relatively hot especially at noon. But if the temperature drops significantly today and is colder than in previous years, then the next summer will be hotter. As we often say, the autumnal equinox is cold, and the weather in summer is bad. Of course, maybe there are places where the autumnal equinox is cold and the weather is bad on March 9th. ?Such a statement. ?

Proverb: The conclusions drawn by each region over time are often not suitable for the whole country. Our country spans a vast area from north to south, and each region has its own unique climate, topography, eating habits, and living habits. The weather here today is just right, neither hot nor cold, cloudy in the morning and sunny in the afternoon. I hope the winter will be warmer and next summer will be cooler. The autumnal equinox is the sixteenth solar term among the twenty-four solar terms, that is, when the sun reaches 180 degrees longitude, about 15 days after the Bailu solar term. It is the fourth solar term in autumn, usually in late September of the Gregorian calendar every year. The autumnal equinox is the same as the vernal equinox half a year ago. The sun always shines directly on the equator. The difference is that the vernal equinox is when the sun's direct point moves from south to north and passes through the equator, while the autumnal equinox is when the sun's direct point moves from north to south and passes through the equator. Because the sun shines directly at the equator, the geographical phenomena are the same. During the spring and autumn equinoxes, day and night are of equal length all over the world. ?

However, after the autumnal equinox, the sun’s direct point enters the southern hemisphere, and various parts of the northern hemisphere enter a season of short days and long nights. Polar night begins to appear near the North Pole; while various parts of the southern hemisphere enter a season of long days and short nights, and the Antarctic Sunlight begins to appear near the point. For our country, the autumnal equinox is a climate turning point. In the southern region of our country, usually after the autumnal equinox, autumn may truly begin in the meteorological sense. So, how is the autumn situation in our country this year? Taking Zhejiang Province as an example, Hangzhou officially entered autumn on September 17, which is significantly earlier than in previous years. In the past five years, autumn in the meteorological sense of Hangzhou has always been in mid-to-early October. ?

Let’s recall that Zhejiang Province entered the plum rain season at the end of May this year, about 20 days earlier than in previous years. In addition, autumn has entered earlier, so it is very likely that winter will begin earlier this year. From the perspective of climate anomalies, 2020 is a "La Niña" year. La Niña phenomena usually have an aggravating effect, such as more precipitation in the rainy season, hotter high-temperature seasons, less precipitation in the dry season, or colder low-temperature seasons. From this perspective, during this year's plum rainy season in the south, the precipitation was significantly higher than the average in previous years, which is a manifestation of the La Niña phenomenon. Therefore, it is possible that this winter will also be a very cold "cold winter". ?

Summary: Winter counts thirty-nine, and summer counts three volts. March 9th is the coldest time in winter. The autumnal equinox is strangely cold and the weather is bad. It's not weirdly cold, and the weather isn't bad. The so-called strange means unusual, especially hot and cold. The so-called bad means that it is extremely hot and cold, which is different from usual. Of course, now that science and technology are advanced, weather forecasts can predict weather changes for a long time in the future. It cannot be said to be 100% accurate, but it is still more convincing than folk proverbs.
