Does it thunder all the year round? Regardless of season?

Thunder does not distinguish between seasons.

Lightning is a discharge phenomenon in thunderstorm clouds. The formation of thunderstorm clouds should meet certain conditions, that is, there should be enough water vapor in the air, the power to make wet air rise, and the air should be able to produce strong convection. Spring and summer are affected by the warm and humid airflow in the south, with humid air and strong solar radiation. The air near the ground is constantly heated up, and the upper cold air sinks, which is easy to form strong convection, so there are many thunderstorms and hail.

In winter, controlled by the continental cold air mass, the air is cold and dry, the solar radiation is weak, and the air is not easy to form violent convection, so thunderstorms rarely occur. But sometimes the weather is warmer in winter, and the force of warm and humid air flow is stronger. When the cold air in the north occasionally goes south, the warm and humid air is forced to rise, and the convection intensifies, so-called "thunder into winter" phenomenon will occur.

Meteorologists say that the occurrence of thunderstorms does not depend on the temperature itself, but on the upper and lower distribution of temperature. In other words, although the temperature is not high in winter, if the temperature difference between the upper and lower reaches a certain value, strong convection can also be formed, resulting in thunderstorms.

Lightning protection notice:

Electric shock accidents are prone to occur in summer. First, because the weather is hot and rainy, the human body secretes a lot of sweat, so it is easy to conduct electricity when using electrical appliances. In addition, due to the increase of thunderstorms, outdoor lightning protection should be paid attention to to avoid electric shock accidents.

(1), pay attention to close the doors and windows, indoor personnel should stay away from doors and windows, water pipes, gas pipes and other metal objects.

(2) Turn off household appliances and unplug the power plug to prevent lightning from invading from the power cord.

(3), when outdoors, to avoid in time, don't stay in the open field. When there is nowhere to hide in the open field, try to find a low-lying place (such as a pit) to hide, or squat down immediately to reduce the height of your body.

(4) Stay away from isolated trees, iron towers, telephone poles and billboards.

(5) Immediately stop outdoor swimming, boating, fishing and other water activities.

(6), such as outdoor * * * many people, don't crowd each other, in case of being struck by lightning, current mutual conduction.
