What is wind?


Wind is a kind of weather. It is the movement of air, blowing from a particular direction. But have you ever thought about what makes the wind blow or where it comes from?

Wind is made by air moving around in the atmosphere – the gases that surround our planet. When these gases are warmer, they move higher up in the sky; when they are cooler, they stay closer to the Earth’s surface.

When the Sun shines on the Earth, the air warms up. Then, as it cools down it sinks again. We can feel it when cooler air moves to fill in the space that rising warm air leaves behind, and we call that air movement ‘wind’.

The strength of the wind is measured in ‘knots‘, which are also used to measure how fast things move at sea. The Beaufort Scale is used as a way of measuring wind speed and to describe how windy it is. When there is no wind, it is described as ‘calm’. The strongest wind is called a ‘hurricane’.

The Met Office has a great video about wind and a list of the top-10 windiest places in the UK.
