Light snow is cold, and it will snow.

It will snow when the light snow is cold, which means that the climate is already cold and it will snow when it is light snow.

The ancient book "Qunfangpu" said: "The light snow is cold and it will snow, but the ground is cold and the snow is not big." That is to say, in the "light snow" solar term, due to the cold weather, the form of precipitation changed from rain to snow, 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. "Light snow" is a festival reflecting weather phenomena, which is the original meaning of the solar term "light snow". Light snow, like rain and Grain Rain, is a solar term that directly reflects precipitation.

Light snow solar term is a solar term with high frequency of cold wave and strong cold air activity. The light snow solar term does not necessarily snow, but refers to the light snow season, when the temperature drops to the point where it can snow. However, because the surface temperature is not low enough, even if it falls, the snowfall will be small or even absent. So whether it will snow this day depends on the current weather.
