Why does the weather thunder?

Lightning is formed in the process of atmospheric movement, which is caused by intense triboelectricity and the cutting of magnetic lines by clouds.

When dust, ice crystals and other substances in the air roll in the cloud, they are positively charged and negatively charged through some complicated processes. After exercise, heavier substances with the same charge will reach the lower part of the cloud (generally negative charge), and lighter substances with the same charge will reach the upper part of the cloud (generally positive charge). In this way, the collection of charges of the same sex forms some charge centers. When the air between the charged centers of the opposite sex is broken down by its strong electric field, "cloud discharge" (that is, lightning) is formed.

When negatively charged clouds approach the ground downwards, the protrusions and metals on the ground will be induced to be positively charged. With the gradual enhancement of the electric field, Lei Yun will form a downward guide, and objects on the ground will form an upward flashover. When they meet, they will form a discharge to the ground. This is easy to cause lightning disasters.
