What are the characteristics of the autumnal equinox solar terms?

What are the characteristics of the autumnal equinox solar terms? The answer to Ant Manor is as follows:

1, the weather turned cold.

The autumnal equinox solar terms are the solar terms that transition from early autumn to late autumn. By this solar term, most parts of the country have begun to enter the cool autumn. The cold air in the south meets the gradually decaying warm and humid air, and the rainfall will take away the heat on the ground and lower the surface temperature. Therefore, after the autumnal equinox, the weather will gradually cool down and the temperature difference at night will gradually widen.

2. The temperature drops

After the autumnal equinox, the direct point of the sun began to enter the southern hemisphere from the equator, and the northern hemisphere began to have shorter days and longer nights, and the day began to be shorter than the night in a day.

The significance of the autumnal equinox:

It means that in the crisp autumn, day and night are equal.

The autumnal equinox solar term is located on the ninetieth day of autumn, in the middle of autumn, which means to divide autumn equally. At the autumnal equinox, the sun reaches 180 (autumnal equinox), almost reaching the equator of the earth, and the length of day and night in the world is equal. After that, the daytime time will be obviously shortened, the evening time will be gradually extended, and the climate will become much more comfortable.

What is the autumnal equinox?

One is equal share. According to China's ancient beginning of spring, Changxia, beginning of autumn and beginning of winter, the four seasons are divided. The autumnal equinox lives in autumn for 90 days and divides autumn equally.

The second is to divide the day and night equally. At this time, 24 hours a day are divided equally, each with 12 hours. This day is the same as the "spring equinox" day. On the day of the "autumnal equinox", the sun is almost directly at the equator. After that, the position of direct sunlight moved south, and the days in the northern hemisphere became shorter and the nights became longer.

Agricultural proverbs of solar terms in autumnal equinox;

There will be rain in the autumn equinox and a bumper harvest in the coming year.

Autumn equinox rain means that if it rains during the autumn equinox and solar terms, there will be a good harvest in the coming year. There are many such sayings among the people, all of which are based on many years' observation. They are catchy and easy to remember and have been passed down to this day.

On the contrary, if it doesn't rain on the day of the autumnal equinox and solar terms, the harvest performance next year will not be so good. This is a summary of the long-term experience of the ancients. Although there is no scientific basis, the accuracy rate is still relatively high, and the elderly in rural areas believe it.
