The autumnal equinox is the sixteenth of the twenty-four solar terms, and its time is generally from September 22nd to September 24th of the Gregorian calendar every year. There is a very strange geographical phenomenon in the autumnal equinox, that is, the sun reaches 180 degrees on this day, which means that the sun shines directly on the equator of the earth, and most parts of the world are equally divided into 24 hours.

From the day of the autumnal equinox, its climate mainly presents the following three characteristics:

(1) The direct position of the sun moves from the equator to the southern hemisphere. In the northern hemisphere, the days are shorter than the nights until the winter solstice reaches the shortest day, while in the southern hemisphere, the opposite is true.

(2) The temperature difference between day and night will gradually increase, and its amplitude will be higher than 65438 00℃.

(3) After the autumnal equinox, the weather will not be hot and cold, but it will get colder every day until it enters the late autumn season.
