Similarly, the autumnal equinox will bring us a cool climate.

The autumnal equinox solar term is a special one among the 24 solar terms. There are two main characteristics: first, the sun reaches the longitude of the Yellow Meridian 180 degrees on this day, and directly hits the equator of the earth, so the 24 hours of this day are equally divided, each being 12 hours; There is no extreme day and night phenomenon in the world. Secondly, according to the method of seasonal division in ancient China, which took beginning of spring, Changxia, beginning of autumn and beginning of winter as four seasons, the autumnal equinox lived in autumn for 90 days and divided the autumn equally.

2. 1. The position of direct sunlight continues to move from the equator to the southern hemisphere. In the northern hemisphere, the phenomenon that the day is shorter than the night, the day is shorter and the night is longer will become more and more obvious (until the winter solstice reaches the longest night and the shortest day).

2.2. The temperature difference between day and night will gradually increase, and the amplitude will be higher than 10℃.

The autumnal equinox is a good time to harvest cotton and tobacco leaves from green to yellow. Winter wheat has been planted in North China, and the Yangtze River basin and vast areas in the south are busy harvesting late rice and ploughing the land to prepare for rape sowing. Drought and lack of rainfall or continuous rainfall in autumn equinox are the main unfavorable factors affecting the normal operation of Sanqiu, especially the continuous rainfall will make the upcoming crops lodging, mildewing or sprouting, resulting in serious losses. "Sanqiu" is a great help, and the word "early" is the key. Timely harvest of crops in autumn can avoid the harm of first frost and continuous rain, and timely sowing of crops in winter can make full use of heat resources before winter, cultivate strong seedlings to survive the winter safely, and lay the foundation for high yield in the coming year.

The autumnal equinox, the sixteenth solar term in the twenty-four solar terms of the lunar calendar, usually lasts from September 22nd to September 24th every year. The climate in the south began to decline from this solar term. First, on this day, the sun reached the longitude of the Yellow River 180 degrees, and directly hit the equator of the earth. Therefore, in most parts of the earth, 24 hours are divided equally, each being 12 hours. Near the North Pole (90 north latitude) and the South Pole (90 south latitude), the special phenomenon that "the sun circles on the horizon all day" can be observed on this day.

After the autumnal equinox, the northern hemisphere has shorter days and longer nights (shorter days than nights), while the southern hemisphere has longer days and shorter nights (longer days than nights). After the autumnal equinox, the polar night range near the North Pole and the polar sun range near the South Pole gradually expanded. 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.

Autumn equinox solar terms, not only in the north, but also in most parts of the south, began to enter autumn, and the summer heat quickly subsided. The so-called "half-combination of yin and yang" means that at the autumnal equinox, the qi and yin of heaven and earth flourish and yang decline, and they are close to each other. Compared with the lush summer, flowers and trees wither, plants and leaves fall, people's mood is also prone to produce a feeling of desolation and depression. The most typical representative of this "autumn depression" mentality is Song Yu's "autumn sadness is qi" in the Warring States period.

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 on the equator of the earth on this day, and day and night are equal. From then on, direct sunlight began to enter the southern hemisphere, and the northern hemisphere began to have shorter days and longer nights, and the temperature dropped, which was of universal significance throughout the country.

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. Near the North Pole, there are long nights and stars for six months in a year. 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.

Weather and climate

According to the lunar calendar, "beginning of autumn" is the beginning of autumn and ends with "the first frost". The "vernal equinox" is exactly half of the 90 days from beginning of autumn to the first frost. From the day of the autumnal equinox, the climate has three main characteristics: the position of direct sunlight continues to move from the equator to the southern hemisphere, and the phenomenon of short days and long nights in the northern hemisphere will become more and more obvious. The days will gradually shorten and the nights will gradually lengthen (until the winter solstice reaches the longest night and the shortest day); The temperature difference between day and night will gradually increase, and the amplitude will be higher than 10℃. The temperature drops day by day, getting colder every day, and gradually entering the late autumn season. The situation in the southern hemisphere is just the opposite.

In addition, the Yangtze River Basin in China and its vast areas to the north have entered autumn, and the daily average temperature has dropped below 22℃.

The cold air mass in the north began to have some influence. In most areas, the rainy season has just ended, with a cool breeze blowing gently, the sky is high and the clouds are light in Wan Liqing, the air is crisp in autumn, the sweet-scented osmanthus is fragrant, the crab is fat and the chrysanthemum is yellow, and the autumn equinox is a beautiful and pleasant season.

The characteristic of rapid seasonal cooling makes the "Sanqiu" of autumn harvest, autumn ploughing and autumn planting particularly nervous.

The autumnal equinox doesn't appear, so cut it and feed it to the old cow. Heading and flowering of double-cropping late rice in South China is the key period for yield formation. The "autumnal equinox" weather formed in advance in low temperature and rainy weather is the main threat to the flowering and fruiting of double-cropping late rice, so we must do a good job in forecasting and defense.
