How is thunder formed and why does it fall from the sky?

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 the exercise, the heavier substances with the same charge will reach the lower part of the cloud (generally negative charge), and the 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 will form some charge centers. When the air between opposite charged centers is broken down by its strong electric field,

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.

Hope to adopt. Thank you.
