What is the thunder when it snows?

It thunders when it snows because it is cold in winter and the water vapor in the atmosphere condenses into ice crystals to form snowflakes. When snow falls from the cloud, it will collide with ice crystals and water droplets in the cloud to generate static electricity, which will accumulate in the cloud and form charge separation. When the charge separation reaches a certain level, a strong electric field will be generated. When the electric field is strong enough, it will cause the molecules in the air to ionize and form an electric current. This current will produce lightning, which is what we see.

Thunder is a natural phenomenon. When it rains, the clouds in the sky have some positive poles and some negative poles. When two clouds meet, they will emit lightning and a lot of heat, which will make the surrounding air 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. Generally speaking, there are two conditions for the formation of thunderstorm clouds: 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, lightning is rare, but sometimes when the temperature is high in winter, thunderstorm clouds are formed, which leads to lightning, rain and snow, especially strong convection, and hail, which will produce the so-called "winter thunder" weather.

Lightning protection description

When it thunders and rains, it is forbidden to stay at the top of the mountain or in hilly areas. More importantly, it is forbidden to continue to push the rain scene to the heights. You shouldn't hide under a big tree or near a telephone pole, nor should you walk or stand in an open field. You should hide in a low-lying place as soon as possible, or try to find a house or a dry cave to hide.

In thunderstorm weather, don't use an umbrella with a metal handle. Take off glasses, watches and belts with metal frames. If you travel by bike, you should leave the bike as soon as possible and stay away from other metal objects to avoid being struck by lightning. Don't go swimming, boating and fishing in rivers and lakes in thunderstorm weather.

When there is lightning, thunder and rain, if tourists rest in the hotel, they should immediately turn off the indoor TV, tape recorder, stereo, air conditioner and other electrical appliances to avoid conduction. It's safer in the middle of the room when it thunders. Don't stay directly under the electric light, and don't lean against posts, walls, doors and windows to avoid accidents caused by induced electricity.
