How is thunder formed and why does it fall from the sky?
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, which is easy to cause lightning disaster.
Lightning is formed in the process of atmospheric movement, which is caused by intense triboelectricity and the cutting of magnetic lines by clouds.
The most common forms of lightning are dendritic, spherical, flaky and banded. The forms of lightning include cloud lightning, cloud lightning and cloud lightning.
When lightning strikes between clouds, the friction between clouds forms lightning.
