During the light snow solar term, the westerly circulation dominated the atmospheric circulation in all areas of China, as follows:

We all know that there are 24 solar terms in China, and each solar term has a different meaning. Xiaoxue is located in the twentieth solar term of the twenty-four solar terms, and the time is165438+1October 22nd or 23rd of the Gregorian calendar every year. So what does the light snow solar term mean? Do you know that?/You know what? Do you know that?/You know what?

The light snow solar term does not mean that it will snow that day. In ancient times, it described the solar terms of Xiaoxue as follows: "Xiaoxue is cold and it will snow, but the ground is not even cold and the snow is not big." In other words, the arrival of the light snow solar terms indicates that the weather is getting cold and there is snowfall.

But the degree of cold is not enough, and the snowfall is not so great, so it is called light snow. Light snow is a season that reflects weather phenomena. There is little snow, and there is no snow on the ground. This is the original meaning of Xiaoxue solar terms.

So light snow represents the initial time and degree of snowfall. Light snow, like rain and Grain Rain, is a solar term that directly reflects precipitation. In ancient times, there was a proverb that said, "There will be a bumper year in the coming year when there is light snow all over the sky." This sentence has three meanings. One is light snow, which will be soaked by rain in the coming year. There is no major drought or flood.

Secondly, snow can freeze some germs and pests to death and reduce the occurrence of pests and diseases in the coming year. Thirdly, snow can keep warm, which is conducive to the decomposition of soil organic matter and enhance soil fertility. In other words, if it snows on the Light Snow Festival, the next year will be a bumper harvest year. This is also the same meaning as what we usually hear, "snow is good for a good year."

Therefore, the arrival of the light snow solar term means that the weather will get colder and colder. Many young people may not have a deep understanding of these solar terms, but our parents' generation regards these solar terms as important information to distinguish the climate. For example, I listen to the ballad "Count Nine Days" that my mother often says. Therefore, we can also appreciate our traditional culture and people's wisdom from the 24 solar terms.

Light snow is also the second solar term in winter. As the weather gets colder and colder, I hope everyone will keep warm and eat more warm food. Go out to bask in the sun, strengthen physical exercise and prevent colds.
