"Light snow" is a solar term reflecting the climate characteristics. There is no necessary connection between the light snow in solar terms and the light snow in the weather. The meaning of "light snow" in solar terms is different from that in daily weather forecast. Xiaoxue solar term is a climate concept, which represents the climate characteristics during Xiaoxue solar term. The light snow in the weather forecast refers to the snow with less snowfall intensity.

Climatic characteristics

In ancient China, Xiaoxue was divided into three stages: "

After a while, Hirozo disappeared;

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

Third, the weather was blocked and turned into 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.

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.
