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". ..

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, the solar term with the largest annual snowfall in the middle and lower reaches of the Yellow River and its vicinity is neither "light snow and heavy snow" nor "slight cold and severe cold", but a "rainy" solar term in spring.
