"Snow" is the product of cold water vapor, which represents cold and precipitation. The climate in this season is not deep and the precipitation is not heavy, so "light snow" is used to compare the climate characteristics of this season. "Light snow" is a metaphor, which reflects the active cold current and increasing precipitation during this solar term, not a small amount of snow under this solar term.
During the light snow solar term, a relatively stable meridional circulation has been established in East Asia, and there is often a low pressure or trough in Siberia. When moving eastward, there will be a large-scale cold air heading south, and there will be a large-scale gale and cooling weather in southeastern China.
The light snow solar term, like the heavy snow solar term, is a solar term reflecting the changing trend of temperature and precipitation, and it is a reflection of ancient farming culture on festivals. Light snow is a solar term with high frequency of cold wave and strong cold air activity. The arrival of light snow solar term means that the weather will get colder and colder and the precipitation will increase gradually.
After the light snow festival, some farmers began to make sausages and bacon, and stored the excess meat in traditional ways until the Spring Festival.
