What season does fear belong to?

The "fright" in the 24 solar terms belongs to spring.

Sting is one of the 24 solar terms, and spring is the third solar term. Twenty-four solar terms were originally formulated on the basis of the "Big Dipper Cycle Rotation", which is closely related to the change of natural rhythm.

At present, solar terms are determined according to the degree of the ecliptic, that is, it is divided into 24 equal parts on a "ecliptic" with a circumference of 360 degrees, arranged according to the degree of the ecliptic, and every 15 is a solar term. Nailing, the sun reaches 345 degrees of the yellow meridian, which is a shocking solar term, equivalent to March 5-6 in the solar calendar.

Meteorological change

Generally speaking, on March 5 or 6 every year, the temperature rises rapidly and spring thunder gradually sprouts. According to the general climate law, the weather all over the country has begun to get warmer and there is more and more rain. Since the solar term, most parts of China have entered the spring ploughing season.

There is a folk saying that "spring thunder rings and everything grows". "When you wake up, you wake up the hibernating insects." And so on, these are shocking characteristics of solar terms. In the season of fright, the spring is budding, and nature has a new vitality, showing a thriving scene.

In China, the time when the spring thunder begins to ring is different from morning till night. On average for many years, thunder can be heard in southern Yunnan around the end of 1, and the first thunderstorm day in Beijing is in late April. The theory that thunder begins with you is consistent with the climate law south of the middle and lower reaches of the Yangtze River. ?

Stunned, with the sharp rise of temperature, the sphere of influence of spring has also expanded obviously. China has a vast territory, and there is a big difference between the north and the south in the progress of entering the spring. During the period of fright, the territory of spring obviously expanded northward, from central Hubei and northwestern Jiangxi to northern Henan and southwestern Shaanxi. At this point, most of the south has entered spring. Although it is still winter in most parts of the north, it will be much warmer.

Phenological phenomenon

1, the spring thunder began to ring.

The symbolic feature of the shocking solar terms is that spring thunder suddenly moves and everything is full of vitality. Judging from the natural phenological process in various parts of China, due to the large span between north and south, the time when spring thunder begins to ring is different in the morning and evening. In the atmosphere all year round, the influence of spring thunder is mainly in the southern region, and the first thunder has not yet come in the northern region. ?

Spring thunder in the sky awakens sleeping animals, which is called "shock". Insects hide in the soil in winter and don't drink or eat, which is called "sting". When the sting season came, the stinger ran away in surprise. In fact, insects can't hear thunder. Spring is back, and the warmer weather is the reason why they end their hibernation and "run away in surprise".

2. Three stages of fear

Scare is divided into three stages: "one is when the peach blossoms first bloom, and the other is when Cang Geng (oriole) sings;" Three waiting eagles turned into pigeons. " The description is mid-spring, peach blossom red, pear blossom white, orioles singing and swallows coming.

According to the general climate law, the weather in all parts of the country began to get warmer, with more rain, and most areas entered spring ploughing. When all kinds of insects dormant and hibernating in the soil are awakened, eggs in winter will also begin to ovulate. It can be seen that fright is a solar term reflecting natural phenology.
