What is the thunder and lightning in winter?

Thunderstorms in winter are caused by strong warm and humid air currents. When encountering strong cold air, the warm and humid air in the lower layer is forced to rise, resulting in strong convection, which creates conditions for the formation of lightning. Thunder in winter, commonly known as winter thunder or winter thunder. In winter, the weather of thunder for winter is not common, but it does exist. In winter, the rainfall is obviously reduced and the weather is dry. Thunder in winter means it's cold and snowy.

Lightning is a discharge phenomenon in the atmosphere, which is mostly formed in cumulonimbus clouds. Cumulonimbus clouds will move with the change of temperature and airflow. When triboelectricity moves, it will form charged clouds, some of which are positively charged and some are negatively charged. As we all know, the contact of positive and negative charges will produce electric energy. Because of the constant collision and friction between clouds, a lot of electric energy will be generated, which will be stored and stored continuously, and at the same time, it will produce strong light.

Because the temperature is very high when discharging, the air expands rapidly when heated, and then there is the roar of explosion, which is lightning and thunder. Understanding its formation process is helpful for us to understand why it thunders in winter, because there are a lot of cumulonimbus clouds with positive and negative charges in the sky in winter, which is a prerequisite for thunderstorms.
