Imagine that ancient poem describes the scene in the light snow season.

The ancient poem describing the scene of light snow season is that mica powder is scattered all over the world.

It is a seven-character poem written by Lu Wengui, a poet of the Song Dynasty, "A Light Snow in the Late October". This poem expresses the feeling of cold in winter by describing the sudden cold and light snow in late October. ?

The wind blew through the house, and the waves were so big that the ink could not be swept away. The world is sprinkled with mica powder, and the world is called bean paste ash. Fine people * * * like new wheat, and Lao Tzu must explore early plum first. Fear of jade forbidding, count on the future.

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.

Light snow is a climatic concept, and its climatic factors include precipitation, temperature and light. The name of light snow, because "snow" is the product of cold weather, the climate is not deep and the precipitation is not heavy during this solar term, so "light snow" is used to compare the climate characteristics during this solar term.

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. The solar term "light snow" is not necessarily related to 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.

Xiao Jingwei said: "On the fifteenth day after (beginning of winter), there was a light snow. The sky and the earth are overcast, the temperature is rainy, and the cold is snowy. At that time, those who talked less were not cold and the snow was not heavy. " Xiaoxue solar term is a climate concept, which represents the climate characteristics during Xiaoxue solar term. Climate factors include precipitation, temperature and light, among which precipitation is an important factor of climate.

Light snow is a solar term reflecting the changing trend of temperature and precipitation. Meteorology, rain, snow, hail and other water vapor condensation falling from the sky to the ground are called "precipitation".

The name of light snow, because "snow" is the product of cold weather, the climate is not deep and the precipitation is not heavy during this solar term, so "light snow" is used to compare the climate characteristics during this solar term. The arrival of the light snow solar term means that the weather is getting colder and colder and the precipitation is increasing.
