What does the light snow solar term mean?

The meaning of light snow solar terms: due to the cold weather, the precipitation form changes from rain to snow, but at this time, because the ground is not very cold and the amount of snow is not enough, it is called light snow.

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.

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. Xiaoxue solar term is a climate concept, which represents the climate characteristics during Xiaoxue solar term. The light snow in the weather forecast refers to the snow with less snowfall intensity. Light snow solar term is a solar term with high frequency of cold wave and strong cold air activity.

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 large range of cold air going south, and there will be a large range of strong winds in East China to raise the temperature. Due to global warming, snowfall in parts of southern China will be delayed, while in the north, it has entered the freezing season.

Xiao Xue Sanhou

Wait a minute: the rainbow is hidden.

A rainbow is a rainbow, which can also be understood as rain. In other words, when we enter the light snow solar term, the form of precipitation gradually changes from rain to snow. If there is no rain in the sky, there will naturally be no rainbow.

The second stage: the weather rises and the atmosphere drops.

This reflects the ancient concept of yin and yang. The sky is yang, the earth is yin, and the yang rises and is gloomy. Yin and Yang no longer intersect, and there is natural silence between heaven and earth. This is actually the ancient people's understanding of climate and life.

Three stages: entering winter

Winter in ancient times was much more difficult than today. There are no birds and animals between heaven and earth. After sowing the last winter wheat, people also hid in the house and began to spend the winter. The so-called "blocking the winter" is exactly what it means.
