Why does it thunder when you are scared?

1, Jingming is the most striking. For example, "it thundered before the earthquake, and the clouds could not open for forty-nine days." When the solar term is suddenly cold and warm, the proverbs that predict the weather in the later period according to the cold and warm are: "Cold weather is warm in spring" 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, you will blow the north wind, and if you are afraid, you will spend the winter from the beginning." If you are afraid, you will blow the south wind, and the seedlings will be late. Modern meteorological science shows that the occasional thunder before and after the "fright" is caused by the increase of earth humidity, which leads to the rise of hot air near the ground or the strong and frequent activity of hot and humid air in the north. 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. The saying that "thunder begins with thunder" is only completely in line with the climate law of the Yangtze River basin.

2. In ancient China, the fright was divided into three stages: "When the peach blossoms first opened; Second, wait for the sound of Cang Geng (Huang Li); Three waiting eagles turned into pigeons. " It describes the season when peach blossoms are red, plum blossoms are white and orioles are singing, and most places have entered the time of spring ploughing. When all kinds of insects dormant and hibernating in the soil are awakened, eggs will begin to ovulate in winter, which shows that the fright is a real solar term reflecting natural phenology.
