The origin and characteristics of light snow

The origin and characteristics of light snow are as follows:

1, the origin of light snow

The origin of chasing light snow should start from the twenty-four solar terms. The solar terms in China originated from the Yellow River Basin. As early as the Spring and Autumn Period, four solar terms were set, namely, mid-spring, mid-summer, mid-autumn and mid-winter. After continuous improvement and perfection, by the Qin and Han Dynasties, the 24 solar terms had been completely established.

In BC 104, the taichu calendar written by Deng Ping officially set 24 solar terms in the calendar, and defined the astronomical position of the 24 solar terms. Twenty-four solar terms are the result of long-term observation, exploration and summary of astronomy, meteorology and climate by laborers in China. So, this is the origin of Xiaoxue solar terms.

2. Characteristics of Xiaoxue

The characteristics of Xiaoxue solar term are: Xiaoxue is the twentieth solar term among the twenty-four solar terms and the second solar term in winter. The time is Gregorian calendar165438+1October 2 1 or 22 or 23, that is, when the sun reaches 240. 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.

During this solar term, the climate is not deep and the precipitation is not great, so "light snow" is used to compare the climate characteristics during this solar term. "Light snow" is a metaphor, which reflects the active cold current and increased precipitation in this solar term, rather than the light snow under this solar term.

The custom of light snow solar terms:

What are the folk customs of light snow and solar terms? There are pickles and bacon. There is a proverb in Nanjing: "Light snow pickles, heavy snow pickles." After the light snow, every household began to pickle and air-dry all kinds of vegetables for winter consumption. Hangzhou people often use this solar term to start pickling salted duck and bacon.

After the light snow solar term, the temperature will drop sharply and the weather will become drier and drier. This is a good time to process bacon. After the light snow festival, some farmers began to make sausages and bacon, and stored the surplus meat in the traditional way until the Spring Festival.

During the light snow, fishermen in the south-central coastal area of Taiwan Province Province will start drying dried fish and storing dry food. The mullet group will come to the Taiwan Province Strait around the light snow, including swordfish and sand fish. Taiwan Province Province proverb: October beans are too fat to see the head, which means that you can catch "bean fish" in October of the lunar calendar in the cloth bag area of Chiayi County.
