What are the characteristics of the 24 solar terms?

A brief introduction to the characteristics of the solar terms: What are the characteristics of the 24 solar terms?

The folk proverb says, "When the spring thunder rings, everything grows." "When you wake up, you wake up the hibernating insects." These are the characteristics of the shocking solar terms.

Sting means that when the weather gets warmer, the spring thunder begins to sound, awakening the insects that are dormant and hibernating underground. Sting means hiding. In fact, insects can't hear thunder. When spring comes back, the natural rhythm is the reason why they end their hibernation and "run away in surprise".

During the period of fright, all kinds of stingers feel that they have started to move. Spring thunder suddenly moves, rain increases, temperature rises, and everything is full of vitality. It is a good time for everything to grow, and this crop can be planted.

After the shock, the temperature rose rapidly, and spring thunder gradually appeared in most areas south of the middle and lower reaches of the Yangtze River. In the northwest of North China, except for a few years, it usually doesn't thunder until Qingming. As a solar term with the fastest annual temperature rise, except for the winter scenes in the northeast and northwest, the average temperature in most parts of the north has risen above 0℃, the daily average temperature in North China is 3-6℃, the temperature in the south of the Yangtze River is above 8℃, and the temperature in Southwest China and South China has reached 10 to 15℃, which is already a harmonious spring with sunshine hours. A year's plan lies in spring, which is a good season for farming. As the temperature rises, all parts of China gradually enter the spring ploughing season from south to north.

Climatic characteristics of the solar terms of fright;

Spring thunder, everything grows. "September is a sunny day, the temperature rises, the rain increases, and farmers have no leisure. It can be described as Heshui Zuo's "a thunderbolt startled snakes and insects, and several showers were raining purple. 1999, the wind in the south of the Yangtze River warmed up and the green fields began to plow in spring. "At this time, the average temperature in most parts of China has risen above 0℃ except for the winter scenes in the northeast and northwest. The average daily temperature in North China is 3-6℃, the temperature in the south of the Yangtze River is above 8℃, and the temperature in southwest and south China 10- 15℃ is already a harmonious spring.

"Spring thunder scares thousands of insects", but the warm climate conditions are conducive to the occurrence and spread of many diseases and insect pests, and weeds in the fields sprout one after another. It is necessary to do a good job in pest control and intertillage weeding in time. "Peach blossoms come, swine fever comes", and we should also pay attention to the epidemic prevention of poultry and livestock. At this time, the temperature rose rapidly, and spring thunder gradually appeared in most areas of the Yangtze River Basin. In most parts of southern China, the first sound of spring thunder can also be heard in the perennial rain and stormy waves; In the northwest of North China, except for a few years, it usually doesn't thunder until Qingming.

Thorns and thunder are the most striking. For example, "it thundered before the earthquake, and the clouds could not open for forty-nine days." The solar term of fright is in the middle of cold and warm weather. According to the cold and warm weather, there are proverbs to predict the weather in the later period: "Cold fright, warm spring equinox" and so on. The wind with prickly knots is also used as a basis for predicting the weather in the later period. For example, "if you are afraid of the north wind, you will spend the winter from the beginning" and "if you are afraid of the south wind, you will plant seedlings later". Modern meteorological science shows that the occasional thunder before and after the "wake-up" is due to the increase of earth humidity, which leads to the rise of hot air near the surface or the strong and frequent northward movement of hot and humid air. 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. Thunder can be heard in southern Yunnan around the end of 1, and the first thunder day in Beijing is in late April. The saying that "thunder begins with you" only conforms to the climate law of the Yangtze River basin. For example, Nanjing, Wuhan, Shanghai and other places basically started the first spring thunder this year around the time of the fright.
