The simple contents of Xiaoxue Solar Terms Manuscript are as follows:

Light snow is the twentieth solar term among the twenty-four solar terms and the second solar term in winter. The time is Gregorian calendar1October 22 or 23 165438, that is, when the sun reaches 240 degrees of the yellow meridian. 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. The arrival of the light snow solar term means that the weather is getting colder and colder and the precipitation is gradually increasing.

Snow is the product of cold weather, so "light snow" is used to compare the climate characteristics of this solar term "the climate is not deep and the precipitation is not heavy" The light snow solar term reflects the changing trend of temperature and precipitation, and does not mean that there is a small amount of snow under this solar term. There is no necessary connection between the light snow in solar terms and the light snow in the weather.

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.

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 snow depth on the ground 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 or heavy snow, nor slight cold or severe cold", but the solar term of spring rain.

The poem about solar terms and light snow is as follows:

Flowers and snow are never tired of seeing in the wind, and I would rather lose the forest. The sad man is under the book window, and the cold is flying. The new snow is like a flower, floating in the wind, and I never tire of it. I sit at the window and enjoy the snow leisurely. The world is cold.

When the clouds darkened, they began to grow slightly. I heard that the window was spilled. I am most worried about dogs barking in the north and south, and I am afraid that the north wind will fly back. Dream brocade can cut out good sentences, and sideburns can weave cold clothes. Sleeping on the stove is difficult to support. Call Plum Blossom to help. It was dark, and the thick cymbals fell on the enough paper with a bang. I can't help but worry that the barking of dogs will break this tranquility, and I am afraid that the howling of the north wind will destroy this elegance.
