How exactly is lightning formed?

Lightning is formed because a large number of positive and negative charges in the sky gather together to cause strong discharge. In the hot summer, we often see a dark cloud suddenly floating in the sky, followed by several sharp lightning, and then the sky thundered and the rain poured down. This is a normal weather phenomenon in summer and contains rich physical principles.

First, the characteristics of lightning Lightning refers to the strong discharge phenomenon between clouds, between clouds and the earth, or between different parts of clouds. Lightning can be divided into linear lightning, spherical lightning and purple lightning. What we see most often is linear lightning. Generally speaking, lightning and thunder happen at the same time, but what we see is thunder first and then lightning, because their propagation speed in the atmosphere is very different.

Second, the reason for the formation of lightning When the sky is about to rain, the cumulonimbus layer in the sky is very thick. The positive and negative charges in the cloud attract each other, but the air will stop them. The positive charge extends upward and rushes to tall buildings such as trees and mountains, while the negative charge extends downward and is close to the ground. Finally, the positive and negative charges finally meet, and a huge current is generated instantly, which causes a strong discharge phenomenon and forms lightning.

Third, lightning protection outdoors, if you encounter lightning, you should take preventive measures in time to avoid personal injury caused by lightning. At this time, we need to do it. Don't venture out easily unless absolutely necessary. Close doors and windows indoors, stay away from metal objects, try not to make phone calls, and don't worry about collecting clothes on the balcony. In addition, if you are really outdoors and can't avoid lightning, you must not stand under a tree to avoid rain, which is very dangerous.

It is a normal natural phenomenon and contains many wonderful physical principles. Dear readers, do you understand how lightning is formed now? If you don't understand anything, please ask your questions in the comments section.
