Wind is air that is moving at high speeds. It happens when warm and cool air rise and sink. That rising and sinking action makes the air move. Tornadoes are formed in the same way, but in a stronger way. Warm air rises and cold air sinks. There is this giant mass of air and wind called the Jet Stream. The Jet Stream is a system of winds that travel around the planet. The air in the Jet Stream naturally warms up and cools down in different parts of the Earth. When the warm and cold air are in one part of the Earth at the same time, the air naturally moves up and down. That motion moves the air around the two masses of warm and cold air and makes wind. Wind can be powerful when the masses of air (in a thunderstorm or hurricane) are larger and move faster. This is how wind is made in nature!
