Why does it thunder?

There are "+"polar clouds and "-"polar clouds in the sky. When two clouds collide, there will be a large-scale discharge phenomenon, which is lightning. And the spark is thunder!

Why does it thunder?

There are many air currents in the sky, and they are constantly moving. These air currents have some directions.

Run up, some run down, in different directions, at different speeds, some fast, some slow.

Slow down. The movement of airflow makes cumulus in the air move up and down. Friction between clouds makes clouds carry different kinds of charges. Because the same charges repel each other, they are positive and negative.

Charges gather at both ends of the cloud. The faster the air flows, the thicker the clouds, and the more electricity it carries. Cumulus clouds carry electricity.

To some extent, it will neutralize these two charges through air discharge. Because electricity will heat up when it passes through the air, it will make the air empty.

The gas expands rapidly and makes a loud noise. This is a transport mine.

If the charged cumulus is close to the ground, the charge on the ground will be different from that under the cloud due to electrostatic induction.

When the charge reaches a certain level, cumulus clouds will discharge to the ground, which is a ground mine prone to disasters.

Generally speaking, where there are protrusions on the ground, it is easy to discharge from there, so when we are in the wilderness, it will not work.

Take shelter from the rain under the big tree.

Because thunder travels at the speed of sound.

Lightning travels at the speed of light.

So lightning approaching means lightning approaching.

loud voice

If it's far away

After seeing lightning,

Thunder came slowly.

Yes, the thunder is much less.
