Wind is air in motion. Wind forms when the sun heats one part of the atmosphere differently than another part. This causes expansion of warmer air, making less pressure where it is warm than where it is cooler.
Wind is the movement of air across the Earthâs surface and is produced by differences in air pressure between one place to another. Wind strength can vary from a light breeze to hurricane force and is measured with the Beaufort Wind Scale. Winds are named from the direction from which they originate.
