Introduction to the Origin of Xiao Xue

20 17 xiaoxue's time is: Wednesday, 2065438+065438+1October 22nd (that is, the fifth day of the 10th lunar month).

Introduction of light snow solar terms

Xiaoxue is the twentieth of the twenty-four solar terms. 165438+1On October 22nd or 23rd, when the sun reaches 240, it is called the light snow solar term. At this time, the sun is at-2016' at the declination. On this day, Beijing's daylight saving time is only 9 hours and 49 minutes, and the height of the sun at noon is only 29 50'.

During the "light snow" solar term, the bucket handle of the Big Dipper points to the northwest at night (equivalent to 10 on the clock). Every night after 20: 00, if you look at the stars at home, you can see that the Big Dipper sinks in the west, while the W-shaped Cassiopeia rises to the sky. Instead of the Big Dipper, she found the coordinates of Polaris and navigated for the stargazers. The quadrilateral Pegasus is facing the sky, and Orion, which symbolizes the winter starry sky, is already on the eastern horizon.

Entering this solar term, the northwest wind began to become a frequent visitor in China, and the temperature gradually dropped below 0℃, but the earth was not too cold. Although it began to snow, the amount of snow was not large, so it was called light snow. At this time, Yin Qi fell and Yang Qi rose, which led to the impassability of heaven and earth, the imbalance of yin and yang, the loss of vitality of everything, and the occlusion of heaven and earth into the severe winter. The first snow will appear in the area north of the Yellow River, reminding people that it is time to keep out the cold and keep warm.

Introduction to the Origin of Xiao Xue

As the saying goes, "the snow area is tightly sealed" means that after the light snow, rivers and rivers freeze one after another. The agricultural proverb says, "Light snow will make the coming year rich." There are three meanings here. First, there will be light snow, and the rain will be even in the coming year, without major droughts and floods; Second, snow can freeze some germs and pests to death, reducing the occurrence of pests and diseases in the coming year; Thirdly, snow can keep warm, which is conducive to the decomposition of soil organic matter and enhance soil fertility. Therefore, as the saying goes, "Xue Rui is a good year."

The formula for calculating the solar term date of light snow is [y * d+c]-L.

Interpretation of the formula: Y= two digits after the number of years, D=0.2422, L= leap year, 2 1 century C=22.36, and 20th century =23.08.

For example, the date of light snow in 2088 = [88× 0.2422+22.36]-[88/4] = 43-22 = 2 1.165438+1October 21light snow. Exception: 1978 plus 1 day.

Three stages of light snow season:

After a while, Hirozo disappeared;

Second, the weather is rising and the atmosphere is falling;

Third, the weather was blocked and turned into winter.

Explanation: The Yang in the sky rises and the Yin in the ground falls, which leads to the impassability between heaven and earth, and the disharmony between Yin and Yang, so everything loses its vitality, and the heaven and earth are blocked and become a cold winter.

The origin of light snow

In other words, due to the cold weather, the form of precipitation changed from rain to snow in the "light snow" festival, but at this time, because the ground is not very cold, the number of snows is small and the amount of snow is not large, so it is called light snow.
