Will there be lightning in winter? What should I pay attention to when it thunders?

It will thunder in winter. Although the phenomenon of "thunder can't stop winter" is rare, it is not unique, and it occurs in many parts of the country. If the weather is cold and hot, there will be more opportunities for the phenomenon of "thunder and winter".

What is the thunder in winter?

The formation of lightning must meet certain conditions, that is, there must be enough water vapor in the air, there must be power to make warm and humid air rise, and the air must be able to produce strong convection up and down. There are many thunder and lightning in spring and summer, because the warm and humid airflow is active, the air is humid, and the solar radiation is strong. The air near the ground is constantly heated and rises, forming a strong convection up and down, which is prone to thunder and lightning. In autumn and winter, because the air is cold and dry, the solar radiation is weak, the air is not easy to form violent convection, and lightning rarely occurs. However, when the strong warm and humid air flows northward and the cold air is forced to rise, strong convection will also occur, and lightning will appear when it reaches a certain intensity.

Yao, deputy director of the Central Meteorological Observatory, said that the formation of lightning must meet certain conditions, that is, there must be enough water vapor in the air, there must be power to make warm and humid air rise, and the air must be able to generate strong convection.

Through the long-term careful observation of the phenomenon of "thunder in winter", the public summed up the law of "thunder and snow in winter", that is, thunder in winter means that the air humidity is high and it is easy to form rain and snow; There is also a folk saying that "when it thunders in winter, ten cowsheds are empty", which means that when it thunders in winter, the warm and humid airflow is very active and the cold air is also very strong. It's so cold and snowy that even cows may freeze to death.

Matters needing attention in thunderstorm days

thunder

1. When it thunders and rains, it is forbidden to stay at the top of the mountain or in hilly areas. More importantly, it is forbidden to continue to push up the rain scene. You shouldn't hide under a big tree or near a telephone pole, or walk or stand in an open field. You should hide in a low-lying place as soon as possible, or try to find a room floor or a dry cave to hide.

2. Don't use an umbrella with a metal handle in thunderstorm weather. Take off glasses, watches and belts with metal frames. If you travel by bike, you should leave the bike as soon as possible and stay away from other metal objects to avoid being struck by lightning.

3. Don't go swimming, boating and fishing in rivers and lakes in thunderstorm weather.

4. When it is thunderous and stormy, tourists should immediately turn off the indoor TV, tape recorder, stereo, air conditioner and other electrical appliances to avoid conduction. It's safer in the middle of the room when it thunders. Don't stay under the electric light, and don't lean against posts, walls, doors and windows, so as to avoid accidents caused by induced electricity when it thunders.
