What are the origins of Xiaoxue solar terms?

There is a saying in "Twenty-four solar terms": "In the middle of June of 5438+00, it rained and was blown thin by the cold, so it condensed into snow. The words of the villain are not prosperous. " During this period, the weather gradually became cold, and the average first snow period in the middle and lower reaches of the Yellow River was basically the same as the Light Snow Festival. Although it began to snow, the amount of snow was generally small, and it was frozen at night and turned around by day. If the cold air is strong and the warm and humid airflow is active, it may snow heavily. For example, on June 5438+0993165438+1October 15 ~ 20, there were heavy snowstorms in some winter wheat areas in the north. So what is the origin of the light snow season? Let me give you a brief introduction.

The origin of light snow solar terms

"Light Snow" is a festival that reflects weather phenomena. "Xiaoxue" is in the second half of the solar calendar 1 1 and the second half of the lunar calendar in October. There is little snow, and there is no snow on the ground. This is the original meaning of the solar term "light snow". The ancient book "Qunfangpu" says: "Light snow will snow when it is cold, and it will not even snow on the ground, and the snow is not big." In other words, due to the cold weather, the form of precipitation changed from rain to snow in the "light snow" festival, but at this time, because the ground is not very cold, the number of snows is small and the amount of snow is not large, so it is called light snow. So light snow indicates the beginning time and degree of snowfall. Light snow, like rain and Grain Rain, is a solar term that directly reflects precipitation.

There is no necessary connection between solar term light snow and weather light snow.

The meaning of "light snow" in light snow 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. Snow is the product of cold weather. Meteorologically, when the horizontal visual distance is equal to or greater than1000m, the depth of snow on the ground is less than 3cm, and the snowfall in 24 hours is between 0.1-2.4mm, it is called "light snow".

Xiaoxue's Dietary Customs

bacon

After a light snow, the temperature plummeted and the weather became dry, which was a good time to process bacon. After the light snow festival, some farmers began to make sausages and bacon and enjoy food during the Spring Festival.

Eat cake

In some places in the south, there is also the custom of eating Bazin in October of the lunar calendar. In ancient times, Bazin was a traditional festival sacrifice in southern China, which was originally used by farmers to worship the cow god. There is a saying, "October is a ceremony."
