What's the difference between the vernal equinox and the autumn equinox?

1, time is different. The autumnal equinox is the sixteenth of the twenty-four solar terms, and the time is generally from September 22 to September 24 of the Gregorian calendar every year. On the day of the autumnal equinox, the sun reaches the longitude 180, almost reaching the equator of the earth, and the whole world is as long as day and night. The vernal equinox is the fourth of the 24 solar terms. The solar calendar reaches 0, and festivals are held on March 20th or March 2nd1day of the Gregorian calendar every year.

2. The climate is different. The vernal equinox and autumnal equinox are solar terms with special significance in the Spring Festival and autumn. The vernal equinox represents the arrival of warmth and the autumnal equinox represents the arrival of cold. During the spring equinox, China has entered a bright spring except the Qinghai-Tibet Plateau, Northeast China, Northwest China and North China. At this time, the climate is mild, the rain is abundant and the sun is shining, and the wintering crops in most parts of China enter the spring growth stage. In the autumn equinox, most parts of China have entered a cool autumn. The cold air from the south meets the gradually decaying warm and humid air, which causes repeated precipitation and the temperature drops again and again. As people often say, it's time for "an autumn rain and a cold", but the daily precipitation after the autumnal equinox will not be great.
