What are the three phenology in the light snow solar term?

Phenology of light snow solar terms:

In ancient China, light snow was divided into three stages: "When the rainbow disappeared; Second, the weather is rising and the atmosphere is falling; It was blocked three times and became winter. " 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 so-called "light snow in October", that is, light snow is the "spirit of October" and a symbol of October in the lunar calendar. October is the first month of winter, also called "Meng Dong". Winter is the season of hiding. According to Yi Gua's explanation, October is "Kun", a month full of yin. However, China's traditional culture does not treat this kind of "full yin" in isolation. The ancients believed that October was full of yin, but it implied a little pure yang, so it was called "YueYang".

North-South differences during light snow;

During the solar term in beginning of winter, there is snow in most parts of northwest and northeast China. In the light snow solar term, it means that there will be snow in North China. If the beginning of the winter solar term marks the beginning of winter in most parts of northern China, then the direct manifestation of cold air is to make the temperature in these areas gradually reach below 0℃ when the light snow solar term comes.

We all know that precipitation will change from rain to snow only when the air temperature under clouds and clouds is lower than 0℃. Therefore, it is an indisputable fact that the temperature in light snow stage is lower than that in winter stage. The middle and lower reaches of the Yangtze River have entered winter one after another.

Although with the arrival of winter, the precipitation in the whole country has gradually dropped to the lowest point in a year, the rainfall in Jiangnan is still higher than that in Jiangbei. Even if the first snow only appeared in the middle and late June of 65438+February in this area, the rainy weather at this time gave people a feeling of wet and cold rather than cool in late autumn, which was much worse than that of people with heating conditions in dry and cold areas in the north.
