What does the autumnal equinox mean? When is the autumn equinox? It is the sixteenth solar term in the twenty-four solar terms of the lunar calendar, and the time is usually September 23rd or 24th every year. The autumnal equinox means "half" China's ancient book "Spring and Autumn Dew, Yin and Yang in and out" said: "The autumn equinox is half cloudy, so it is cold and hot." The meaning of "autumnal equinox" has two meanings: first, the sun reaches the longitude of the yellow meridian 180 degrees on this day and directly hits the equator of the earth, so a day is divided into 24 hours, every hour 12 hours; There is no extreme day and night phenomenon in the world. After the autumnal equinox, the polar night range near the North Pole and the polar sun range near the South Pole gradually expanded. 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. In ancient China, the autumnal equinox was divided into three periods: "When thunder comes, the sound will stop;" Second, wait for scorpion blank households; Wait for the water to dry. "The ancients thought it thundered because the sun be the spirit is strong, and the yin began to fill after the autumnal equinox, so it didn't thunder. Climatic characteristics: According to meteorologists, according to the lunar calendar, "beginning of autumn" is the beginning of autumn and ends with "the first frost", and the "autumnal 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. At the autumnal equinox, the Yangtze River basin and its vast northern area 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. It is also an important solar term in agricultural production. After the autumnal equinox, the direct sunlight 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. Agricultural proverbs say: "An autumn rain is a cold", "The white dew is divided into autumn nights, and one night is cold." In August, the wild goose gate opens, and frost comes to the foot of the wild goose. "It's not surprising that the northeast cools down early and the autumnal equinox sees frost.

"Equinox" has two meanings:

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.

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.
