Where is the light snow popular? If you don't see it, the wheat grains will shrink.

The saying that light snow does not see snow and wheat grains will shrivel is mainly spread in the northern region.

If it doesn't snow in the light snow festival, the wheat grains may shrink and become less full, which will affect the harvest. Therefore, in the north, farmers began to expect snow during the light snow festival.

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. 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, a large range of cold air will go south, bringing a large 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 light snow in solar terms is different from the light snow 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. In meteorology, a strange rock whose horizontal visual distance is equal to or greater than 1000 meters, the depth of snow on the ground is less than 3 cm, and the snowfall in 24 hours is between 0. 1-2.4 mm, which is called light snow.
