It's the change in air temperature. Cold air heats up and becomes hot air and rises up since hot air is lighter than cold air. The other cold air stays nearer to the ground and that is what causes the winds to blow.

How does wind start a wave?

Wind interacts with the surface of the ocean, creating friction that transfers energy into the water. This energy causes ripples to form, which then develop into waves as the wind continues to blow. The longer and stronger the wind blows, the larger and more powerful the waves become.


How can one learn how to read a wind rose effectively?

To learn how to read a wind rose effectively, one can start by understanding the compass directions and the corresponding wind directions. Then, familiarize oneself with the symbols and colors used on the wind rose to represent wind speed and direction. Practice interpreting the wind rose by studying different examples and comparing them to actual weather conditions. With time and practice, one can become proficient in reading a wind rose accurately.


How fast of wind speed does it take to start a tornado?

Tornadoes typically form in severe thunderstorms when there is a significant change in wind speed and direction, known as wind shear. Wind speeds in a tornado can range from 65 mph to over 200 mph, with faster winds associated with more violent tornadoes.


Is a wind vane considered as a wind speed?

No. A wind vane is an instrument that can tell wind speed but not wind direction.


What weather tool is used to measure wind direction?

An anemometer is used to measure velocity and is the spinning part on a weather station. A weather vane is an instrument for showing the direction of the wind. They are typically used as an architectural ornament on the highest point of a building. On a sailboat, the vane at the top of the mast is called a windex.
