What is the moral of the light snow solar term?

Entering the light snow solar term means that the temperature continues to fall, the weather is cold, and the precipitation state changes from rain to snow.

Light snow, like solar terms such as rain and Grain Rain, is a solar term reflecting precipitation, which is different from what we call light snow with less snowfall every day. If the white dew, cold dew and first frost in the previous solar terms were condensed into water droplets and developed into frost due to the drop in temperature, then the light snow was condensed into snow when the cold dropped below zero.

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 wide range of cold air going south, which will bring a wide range of strong winds and cool weather.

Meteorological changes of light snow

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. Light snow solar terms indicate that a relatively stable meridional circulation has been established in East Asia. When the Siberian depression or trough moves eastward, there will be a wide range of cold air going south, which will bring a wide range of windy and cool weather.

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. Light snow solar term is a climate concept, which reflects the temperature and precipitation.

The "light snow" in the weather forecast refers to the snow with less snowfall intensity. 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". ..
