What is the weather when electricity and thunder appear at the same time?
When it rains, some clouds in the sky are positive and some are negative. When two kinds of clouds meet, they will emit lightning and a lot of heat, which will make the surrounding air heat and expand. Instantly heated and expanded air will push the surrounding air and produce strong explosion vibration. This is thunder.
Lightning is a discharge phenomenon in thunderstorm clouds. Thunderstorm clouds generally have two conditions, sufficient water vapor and strong convection. 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 sometimes when the temperature is high in winter, it will form thunderstorm clouds, leading to lightning and rain and snow. Convection is particularly strong, and it can also form hail, which will produce the weather phenomenon of "thunder in winter". Knowing these reasons, it is not surprising that it thunders in winter.
