light snow (Xiao Xue)

Light snow is the 20th of the 24 solar terms and the second solar term in winter. It is on November 22 or 23 of the Gregorian calendar, that is, when the sun reaches 240 ° of the Yellow meridian. Light snow is a solar term reflecting precipitation and temperature. It is a solar term with high activity frequency of cold wave and strong cold air. The arrival of the light snow solar term means that the weather will be colder and colder and the precipitation will increase gradually.

The reason why this solar term is called light snow is that "Snow" is the product of cold weather. The climate during this solar term is not deep and the precipitation is not large. Therefore, "light snow" is used to describe the climate characteristics during this solar term. "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.

In the light snow solar term, a relatively stable meridional circulation has been established in East Asia. There are often low-pressure or low trough in Siberia. When moving eastward, there will be large-scale cold air going south, and there will be large-scale gale cooling weather in Southeast China.
