Where does the wind come from?

le vent, the wind

Where does the wind come from? The wind comes from the horizontal movement of air.

The sun warms the ground, but not evenly. The sun warms the equatorial regions more and the poles much less. Atmospheric pressure is responsible for large air movements.

Warmer air at the equator will rise. The pressure is lower. It is an area of low pressure.

The air is colder at the poles. It will descend to the ground. The pressure is stronger. This is a high-pressure area.

The warm air that is on the equator will tend to reach the poles. There will therefore be horizontal displacement of the air.

The wind is born!
