The following is an explanation of the meaning of the equinox solar terms. Come and have a look.

What does the autumnal equinox solar term mean 1 1. What does the autumnal equinox solar term mean?

1, the autumnal equinox, which means to split it in half. On the day of the autumnal equinox, the sun shines almost directly on the equator of the earth, and the length of day and night is equal all over the world. After the autumnal equinox, the position of direct sunlight moved to the southern hemisphere, and the northern hemisphere got less and less solar radiation, but the ground lost more heat and the cooling rate was obviously accelerated. By the autumn equinox, the summer heat has disappeared, the weather has turned cold, and the summer heat has separated.

2. The autumnal equinox is the sixteenth of the twenty-four solar terms, and the fourth solar term in autumn usually lasts from September 22nd to September 24th in the Gregorian calendar.

3. In ancient times, there was a folk activity of "Spring Festival to the Sun and the Moon". The autumnal equinox used to be a traditional "offering sacrifices to the moon", and the Mid-Autumn Festival evolved from offering sacrifices to the moon in autumn.

The autumnal equinox means officially entering autumn.

After the autumnal equinox, the direct point of the sun continued to move from the equator to the southern hemisphere, and the days in the northern hemisphere began to shorten and the nights became longer, that is, the days in a day began to be shorter than the nights; The southern hemisphere is the opposite, so the autumnal equinox is also called the landing point.

At the North Pole and South Pole, on the day of the autumn equinox, the sun is on the horizon all day. It is recorded in ancient books: "The autumnal equinox is half cloudy and half sunny, so it is cold and hot day and night." The autumnal equinox means not only equal day and night, but also equal autumn.

After that, as the direct point of the sun continued to move southward, a six-month polar night began near the North Pole, which gradually expanded and then narrowed. A six-month polar day began near the South Pole, which gradually expanded and then narrowed.

The autumnal equinox is in the middle of autumn, so it is called autumnal equinox. By this solar term, it means that we have really entered autumn, geese flying south and migratory birds migrating, which can be said to be a real experience of autumn.

Autumnal equinox is also an important solar term in astronomy. After the autumnal equinox, the direct point of the sun moved to the southern hemisphere, and the northern hemisphere got less and less solar radiation, while the ground lost more heat and the temperature dropped significantly.

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.

Second, the customs.

What does the equinox solar term 2 1 mean? What does the autumnal equinox mean?

The autumnal equinox solar terms are special among the 24 solar terms and have two main characteristics:

First, the time between day and night is equal, with long days and short nights, and short days and long nights. On this day, the sun reaches longitude 180 degrees and points directly at the equator of the earth, so the 24 hours of this day are divided equally, each being 12 hours; There is no extreme day and night phenomenon in the world.

Second, the climate changed from hot to cold. According to the division of seasons in ancient China, which began with beginning of spring, Changxia, beginning of autumn and beginning of winter, the autumnal equinox falls within 90 days of autumn and is divided equally in autumn.

The autumnal equinox is one of the 24 solar terms of traditional festivals in China. On September 22nd, 23rd or 24th of Gregorian calendar, the sun reaches 180 degrees. The meaning of the "twenty-four solar terms" in the autumnal equinox: "See the vernal equinox in mid-August". "Divide" means to divide day and night equally. Like the vernal equinox, the sun shines directly at the equator of the earth, and day and night are equal. Since then, the position of direct sunlight has moved south, and the days in the northern hemisphere have gradually shortened, the nights have become longer, and the temperature has dropped, which is of universal significance throughout the country. At the autumnal equinox, "fen" means "half". At the autumnal equinox, the world is as long as day and night. After the autumnal equinox, the days are getting shorter and shorter in the northern hemisphere, and the nights are getting longer and longer in the southern hemisphere. The characteristics of the autumnal equinox The autumnal equinox solar terms are special among the 24 solar terms. The climate of the autumnal equinox At the autumnal equinox, most parts of China have entered a cool autumn. The cold air from the south meets the warm and humid air that gradually decays, resulting in continuous precipitation and the temperature dropping 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. At this time, the field farming in the south and the north is different. In northern China, there is an agricultural proverb that says: "The white dew is early, the cold dew is late, and it is the right time to plant wheat in the autumn equinox." Proverbs clearly stipulate the sowing time of winter wheat in this area; And "White clouds come in autumn equinox, good songs and good rice seeds are everywhere" reflects the planting time of rice in Jiangnan area. In addition, the taboos of working people on the solar terms of the autumnal equinox are also summed up as proverbs, such as "the autumnal equinox is only afraid of lightning, and more meters are more expensive."

2, symbolizing the autumn harvest.

The autumnal equinox divides day and night equally, and the sun is on the horizon all day, which also symbolizes the joy of autumn harvest. After that, as the direct point of the sun continued to move southward, a six-month polar night began near the North Pole, which gradually expanded and then narrowed. A six-month polar day began near the South Pole, which gradually expanded and then narrowed. "The autumn equinox is half cloudy and half sunny, so it is cold and hot day and night."

What does the autumnal equinox mean? 3. The significance of the autumnal equinox season

The fourth solar term in autumn is the vernal equinox solar term, which is also 16 of the 24 solar terms. [3] ? The autumnal equinox is when the sun reaches 180 degrees on September 23rd or 24th every year. The sun shines directly on the equator of the earth, and the day and night are equally divided, each with 12 hours. There is no extreme day and night in the world. After the autumnal equinox, the direct point of the sun continues to move southward, so the autumnal equinox is also called declination. After that, the temperature difference between day and night will gradually increase, and the range will be higher than 10℃. The weather is very cool.

Second, the origin of the autumnal equinox solar terms

There is a cloud in Chinese ancient books: "The autumnal equinox is half cloudy and half sunny, so it is cold and hot day and night." The autumnal equinox means "half" The autumnal equinox in August is generally around September 22 of the Gregorian calendar. There is an old saying: "The autumn equinox is half cloudy and half sunny, so it is hot and cold day and night." At this time, the sun reaches longitude 180 degrees, pointing directly at the equator of the earth, so the world (except the poles) is divided equally day and night. "beginning of autumn" is the beginning of autumn and ends with "the first frost". The "autumnal equinox" is just half of the 90 days from beginning of autumn to the first frost, so it is called the autumnal equinox, and it is also the season when the weather turns cold.

Third, the custom of the autumnal equinox and solar terms.

1, eat autumn vegetables in the autumn equinox

In some areas of Lingnan, China, Hakkas have the custom of eating autumn vegetables. Autumn vegetable is a kind of wild amaranth, which villagers call autumn Artemisia.

Every family should eat glutinous rice balls, and cook dozens, twenties and thirties of glutinous rice balls, and put thin bamboo forks on the edge of the field every day to stick birds' mouths to prevent them from damaging crops.

Step 3 fly a kite
