Xiaoxue is the twentieth of the twenty-four solar terms. The time is165438+1October 22 or 23 of the Gregorian calendar every year, that is, when the sun reaches 240 degrees of the yellow meridian.

"Light snow" is a solar term reflecting the climate characteristics. In the light snow season, the sky is cloudy, the cold is not deep, and the snow is not big, so it is named light snow.

"Twenty-four solar terms" said: "In mid-October, the rain was thin because of the cold, so it condensed into snow, and the small ones did not bloom."

The ancient book "Qunfangpu" also contains: "A light snow is cold and it will snow, but the ground is not cold and the snow is not heavy."

At this time, although the snow is not full, the world has become silent. At night, the Big Dipper sinks in the west and bucket handle points to the northwest. The weather is cold and winter is getting thicker and thicker.

The arrival of "light snow" means that winter snowfall is about to begin.

Light snow doesn't snow, why is it called "light snow"?

The first reason is that snowflakes are often underdeveloped in the light snow season, and not all of them are snow.

There is a cloud in the Book of Songs: "When it rains and snows, it is first designated as graupel." Often it is not snow at first, but graupel. Like a prelude to snow, graupel has not yet developed into a snowflake.

The second reason is that even the snow in the light snow season often melts with the weather or freezes at night.

In the heavy snow season, it is different. There is less wet snow and more dry snow, which is basically the kind of snow suitable for making snowmen and having snowball fights. It is called "decent snow".

The third reason is that it snows more and more frequently in the heavy snow season. People feel that it begins to snow in the light snow season, and it often snows in the heavy snow season.

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. 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.
