What is the traditional saying of thunder in December?

Thunder in winter, commonly known as "thunder in winter" or "thunder in winter". In winter, "Thunderstorm" weather is not common, but it is not without it.

But in ancient times, due to the underdevelopment of science and technology, people thought that thunder in winter was an ominous sign. Jing Fang, a master of Yi Studies in the Han Dynasty, said, "When there is a thunderstorm, the earth shakes." He believes that the thunder in winter is caused by the indiscriminate killing of creatures in spring and summer. If human beings do not repent, warm winds will blow in winter, causing pests to wreak havoc and plagues all over the world.

The ancients also said, "There are thieves everywhere when it thunders after autumn." They believe that the occurrence of the winter thunder is due to the ruthless administration and abnormal statutes of the imperial court, so the sky is falling and thieves are rampant. Therefore, there is an ancient folk proverb, "Spring thunder does not strike, winter thunder does not hide, and soldiers hurt the country." "In the first month of spring, people don't cook, it's a funeral for the epidemic."

In fact, some abnormal phenomena in the climate occasionally occur. There is a folk saying that "spring flowers thunder in autumn and winter, frogs croak and six snows in spring". In this regard, meteorologists explained that due to the control of the mainland cold air mass, the air is cold and dry in winter, the solar radiation is weak, and the air is not easy to form violent convection, so thunderstorms rarely occur.

However, sometimes in winter, the warm and humid air is stronger because of the warmer weather. When strong cold air occasionally goes south in the north, warm and humid air is forced to rise, and convection intensifies, so-called "thunder into winter" phenomenon will appear. So "thunder in winter" is just a weather phenomenon, which has nothing to do with bad luck, so we should get rid of this superstitious concept and establish a correct scientific view.

Precautions:

Thunder in winter is often a precursor to snowstorms. There is a folk saying that "ten cowsheds are empty when it thunders in winter", which often indicates that the ice and snow are firm, the temperature is low, and livestock are most vulnerable to freezing and death. In addition, Ban Haoran, technical director of Ji Xiang Science and Technology Meteorology, also said in an interview with Science and Technology Daily that traffic accidents and lightning accidents are prone to occur in lightning weather.

Therefore, the Science and Technology Daily reminds us to avoid going out in rainy and snowy weather. If you have to go out, you'd better wear rubber shoes and raincoats, and stay away from power equipment and metal pipes. At the same time, you should also pay attention to the influence of snow and road icing on traffic. The electric power, communication and related departments should do a good job in the prevention of wire icing in alpine mountain areas. When the load of electricity and gas increases in low temperature weather, it is necessary to strengthen the safety protection measures of electricity and gas.
