What is the weather when electricity and thunder appear at the same time?

When electricity and thunder appear at the same time, it is a thunderstorm.

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.

General knowledge of security

1. When there is a thunderstorm and lightning, don't call and answer the phone, but unplug the telephone line. The mobile phone can be used normally, but generally try not to answer the phone outdoors or indoors near the window.

2. Don't turn on the TV, computer, VCD player, etc. Unplug all power plugs during thunderstorms and lightning to avoid personal injury and electrical damage.

3, don't stand under the light bulb, don't take a shower.

4. Try not to go out. If you have to go out, you'd better wear rubber shoes and a raincoat, which can keep out lightning.

5. Try not to open the door or open the window to prevent lightning from hitting the room directly.
