What is the Autumn Equinox

What is the meaning of the autumnal equinox What time is the autumnal equinox Autumn Equinox, the sixteenth of the twenty-four solar terms in the lunar calendar, the time is generally September 23rd or 24th of each year. Autumn Equinox "points" for "half" meaning, China's ancient book "Spring and Autumn flourish dew, yin and yang in and out of the upper and lower chapters," said: "Autumn Equinox, yin and yang half also, so the day and night and cold and heat flat." "Autumn Equinox" has two meanings: First, the sun reaches 180 degrees of yellow longitude on this day, shooting directly at the Earth's equator, so this day is divided into 24 hours of day and night, each 12 hours; the global phenomenon of polar day and night. After the autumnal equinox, the polar night range near the North Pole is growing, the polar day range near the South Pole is growing. Second, according to China's ancient to spring, summer, autumn, winter for the beginning of the four seasons of the seasonal division of law, the autumnal equinox in the 90 days of autumn, the equal division of the autumn. China's ancient fall equinox is divided into three waiting: "one waiting for the thunder began to close the sound; two waiting for the stinging insects blank house; three waiting for the water began to dry." Ancient people believe that the thunder is because the yang qi is full of sound, after the autumnal equinox yin qi began to flourish, so no longer thunder. Climatic characteristics: meteorologists said that, according to the lunar calendar, "Autumn" is the beginning of autumn, to "frost" for the end of autumn, "Autumn Equinox" is exactly 90 days from the autumn to frost! The "Autumn Equinox" is exactly half of the 90 days from the beginning of autumn to the frost. From the day of the autumnal equinox, the climate mainly presents three major features: the location of direct sunlight continues to move from the equator to the southern hemisphere, the northern hemisphere will become more and more obvious phenomenon of the short day and long night, the day gradually becomes shorter and longer night (until the winter solstice day to reach the longest night, the day is the shortest); the day and night temperature difference is gradually increasing, the amplitude will be higher than 10 ℃ or more; the temperature is declining day by day, one day than the day of the cold, and gradually into the late autumn season. The situation in the southern hemisphere is just the opposite. Autumnal equinox, China's Yangtze River Basin and the vast area north of the Yangtze River Basin, have entered the fall, the average daily temperature have fallen to below 22 ℃. Cold air masses in the north began to have a certain force, most areas of the rainy season has just ended, cool breeze, blue sky, wind and sunshine, high and refreshing autumn, danggui fragrance, crab fat chrysanthemum yellow, the autumnal equinox is a wonderful and pleasant time. It is also an important festival on agricultural production, after the autumnal equinox the position of direct sunlight moved to the southern hemisphere, the northern hemisphere is getting less and less solar radiation, while the ground is losing more heat, the rate of temperature reduction is significantly accelerated. Farmer's proverbs say: "an autumn rain a cold", "White Dew Autumn Equinox night, a cold night". "August Yanmen open, geese feet with frost to", the Northeast region cooling early in the year, the autumn equinox frost has been not surprising.

The origin of the autumn equinox China's ancient book "Spring and Autumn flourish dew? Yin and Yang in and out of the upper and lower parts of the chapter, said: "Autumn Equinox, the yin and yang half also, so the day and night are even and cold and heat." The "half" of the autumnal equinox is the meaning of "half".

"Autumn Equinox" means two things:

First, the day and night time is equal, and by the day is long and the night is short gradually short and long. The sun reaches 180 degrees of yellow longitude on this day, shooting directly at the Earth's equator, so the 24-hour day and night on this day, each 12 hours; the global phenomenon of extreme day and night.

Second, the climate from hot to cool. According to China's ancient to spring, summer, autumn, winter for the beginning of the four seasons of the seasonal division of law, the autumnal equinox in the 90 days of autumn, the equal division of the autumn.

The autumnal equinox in the annual calendar September 22, 23 or 24, for the Chinese traditional festival in the twenty-four solar terms, when the sun reaches 180 degrees of yellow longitude. The meaning of the autumnal equinox, "the moon order seventy-two wait collection": "August in the middle of ...... solution to see the spring equinox". "The meaning of the equinox is that day and night are equally divided, and like the vernal equinox, the sun shines directly on the earth's equator on this day, and day and night are equal. Thereafter, the position of direct sunlight to the south, the northern hemisphere tends to be shorter days and longer nights, lower temperatures, in the country has universal significance. Autumn Equinox, "points" means "half". At the time of the fall equinox, the global day and night are equal in length. After the autumnal equinox, the day grows shorter and the night grows longer across the northern hemisphere, and the day grows longer and the night grows shorter across the southern hemisphere." Characteristics of the Autumn EquinoxThe Autumn Equinox is one of the more special of the twenty-four solar terms. Climate of the Autumn Equinox During the Autumn Equinox, most parts of China have already entered the cool fall season, where the cold air moving southward meets the gradually decaying warm and humid air, producing precipitation over and over again and a drop in temperature. As people often say, it has reached the time of "an autumn rain a cold", but the daily precipitation after the autumnal equinox will not be very large. At this time, farming in the north and south is different. In northern China, there is a farmer's proverb that says: "White dew is early, cold dew is late, autumn equinox is the right time to plant wheat." The proverb clearly specifies the time of sowing winter wheat in the region; and "the weather of the autumn equinox white clouds, everywhere good song good rice planting" reflects the time of sowing rice in Jiangnan region. In addition, the working people of the autumn equinox taboo is also summed up in proverbs, such as "autumn equinox is only afraid of thunder and lightning flash, more expensive how to come to the price of rice".
