How is lightning formed?

0. 1-0.3 seconds after lightning, the shock wave evolved into sound wave, which is the thunder we heard.

Accompanied by lightning and rumbling thunder. Sounds like thunder can be divided into many kinds. Thunder as fast and powerful as explosion is called "explosion thunder"; There is also a kind of thunder that lasts for a long time, a bit like the sound made when the mill is pushed, and it is called "Mollaret".

The so-called mine explosion is generally the sound made at the moment when the clouds ionize to the ground.
