There is a folk saying that "thunder in the first month is a bunch of dead people", saying that thunder in the first month of this year will kill many people. I don't know if it's allowed or not. I remember 1989 just after the first month, there were news reports of snow and thunder in Jiangsu Province, Shanghai and Beijing. Only in Jiangsu province, thunderstorms poured down first, then cold air came and it began to snow. When it snowed, thunder continued. Shanghai, a thunderstorm in the middle of the night, heavy snow in the middle of the night, and a vast expanse of whiteness in the morning.
But it seems that it still thundered and rained in the middle of the night in June1992165438+10, and the rain was similar to that in summer. The probability of this kind of weather increases with the increase of temperature. Cold air causes the airflow to rise violently, and intense convection will cause lightning. This is not surprising in science. The folk saying should also be a summary of thousands of years of law, which should have been fulfilled, but it can't be verified.
