How long does thunder usually last?

There is no way to know the exact time of thunder. Thunderstorm weather belongs to nature, but in general, the duration is not long, and this phenomenon rarely lasts more than 1 hour. There are positive and negative clouds in the sky. When two kinds of clouds meet, they will emit lightning and a lot of heat, which will make the air expand when heated. The heated and expanded air will push the surrounding air and cause strong explosion vibration. This is thunder.

Introduction of lightning: 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 a weather phenomenon called thunder in winter. Since the middle of 5438+ 10, the warm and humid air flow has been extremely strong, and the temperature is obviously high. On June 5438+04, the highest temperature reached 22. 1℃, the highest in the same period in history. On June 5438+07, the strong cold air in the north went south and the two met. It not only snowed, but also thundered. Knowing these reasons, it is not surprising that it thunders in winter.
