Light snow is a solar term reflecting precipitation and temperature, and it is a solar term with high frequency of cold wave and strong cold air activity. The arrival of the light snow solar term means that the weather is getting colder and colder and the precipitation is gradually increasing.

This solar term is called light snow because "snow" is the product of cold weather. During this solar term, the climate is not deep and the precipitation is not great, so "light snow" is used to compare the climate characteristics during this solar term. "Light snow" is a metaphor, which reflects the active cold current and increased precipitation in this solar term, rather than the light snow under this solar term.

Snow is the product of cold weather. Meteorologically, the horizontal visible distance is equal to or greater than 1000m, the ground snow depth is less than 3cm, and the snowfall in 24 hours is between 0. 1-2.4mm, which is called "light snow". ..

During the light snow solar term, a relatively stable meridional circulation has been established in East Asia, and low pressure or trough often appears in Siberia. When moving eastward, there will be a large-scale cold air going south, and there will be a large-scale gale and cooling weather in eastern China. Light snow solar terms do not necessarily snow. In fact, the solar terms with the largest snowfall in the whole year are not in light snow and heavy snow. For example, in the middle and lower reaches of the Yellow River and its vicinity, the solar term with the largest snowfall in the whole year is neither "light snow nor heavy snow" nor "slight cold nor severe cold", but "rain" in spring.
