What does the snow solar term mean?

Heavy snow is 2 1 of the 24 solar terms and the third solar term in winter. Heavy snow, fingers crossed, the sun reaches 255 degrees of the yellow meridian, and the node time is February 6-8, 65438. Like light snow, rain, Grain Rain and Xiaoman, heavy snow is a solar term that directly reflects precipitation. The arrival of heavy snow in solar terms means that the weather will get colder and colder and the precipitation will gradually increase. The most common solar terms in heavy snow are cooling, rain or snow.

Snow solar term is a climate concept, which represents the climate characteristics during the snow solar term, namely temperature and precipitation. The significance of heavy snow in solar terms is different from that in weather forecast. In fact, the snow in heavy snow solar terms is often not as big as that in light snow solar terms, and the solar terms with the largest amount of snow in the whole year are not in light snow and heavy snow solar terms. For example, in the middle and lower reaches of the Yellow River and its vicinity, the solar term with the largest snowfall in the whole year is neither "light snow nor heavy snow" nor "slight cold nor severe cold", but "rain" in spring.

The heavy snow season is divided into three periods: "When birds wait, they don't sing;": Second, wait for the tiger to pay; Wait for you to stand out. " In other words, due to the cold weather at this time, Hao Han birds no longer sing; At this time, Yin Qi was in its heyday, the so-called prosperity and decline, Yang Qi had sprouted, and the tiger began to courtship; "Liting" is a kind of bluegrass, which feels the germination of yang and sends out new buds.

People often say that "snow will bring a good harvest". In severe winter, snow covers the earth, so that the temperature around the ground and crops will not drop very low because of the cold current, and winter crops create a good wintering environment. When the snow melts, the soil moisture content is increased to meet the needs of crop growth in spring. The content of nitride in snow water is five times that of ordinary rain water, which has a certain effect on fertile fields. There is an agricultural proverb called "wheat covers three quilts this year and sleeps with steamed bread next year".

Will it snow when it snows heavily?

In fact, before and after the solar term of heavy snow every year, there are not many places where it really snows from south to north in China, and the amount of snow is not particularly large. After all, in terms of precipitation, as the saying goes, "the mountains are high and the moon is small, and the water comes naturally." From the north of Jiangnan in China, the precipitation is relatively small throughout the winter.

Then, why is the solar term without heavy snow called heavy snow? In fact, this heavy snow, like the light snow in the previous solar terms, is all about the probability of snow, or the probability of snow. Just like the severe cold and slight cold in the 24 solar terms, it does not mean that it will be very cold, but describes the degree of freezing on the ground. Heavy snow means that the possibility of snow is increasing. Some scholars also think that light snow is the season when the first snow comes, and heavy snow is the season when snow appears, which is also reasonable. When there is light snow, the snow melts, but when it snows again after heavy snow, there will be snow on the ground.

The ancients divided each of the 24 solar terms into three periods to describe the climatic characteristics of the solar terms more accurately. The three stages of heavy snow are: "At first, birds don't sing." Second, the tiger began to pay. After waiting for three times, I stood up. "

At first, owls (hè and dàn) didn't sing. According to the dialect of Guo Pu in the Jin Dynasty, "like a chicken, hairless in winter, singing day and night, that is, cold insects." The ancients thought that this bird belonged to Yang and was very aggressive, so it was used as a metaphor for fighters. However, the heavy snow solar term is the cloudiest solar term, so the EMU stopped singing before and after the heavy snow.

Second, the tiger began to pay. Heavy snow is the most cloudy solar term, and the so-called "moving against the Tao" also contains the seeds of Yang, which is the concept of the transformation of Yin and Yang in the ancients. As the king of beasts, the tiger felt some budding sun between heaven and earth and began to have mating behavior.

Third, Li stands out. Litchi is a plant, which is what we now call Malanhua. The root system of this plant is very developed and can be used to make brushes. Before and after the solar term of heavy snow, this plant "sprouted new buds because of the sun's sun", which also reflected the concept of the ancient people's transformation of yin and yang, which flourished and declined.
