Will it thunder in winter?

In winter, because the air is cold and dry, the solar radiation is weak, and convection is not easy to form in the air, so lightning is rare.

But in winter, sometimes the temperature is high and the warm and humid air flow is strong. When there is occasional strong cold air going south in the north, the warm and humid air is forced to rise, and the convection intensifies, forming thunderstorm clouds, producing lightning, rain and snow weather, which is particularly strong, and can also form hail, which will produce the weather phenomenon of "thunder in winter".

Formation process:

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.
