Wind is the movement of air in the atmosphere.
Wind is created by changes in air pressure. Air will flow from higher air pressure to lower air pressure on earth’s surface. However, because of earth’s rotation and friction as the air moves across earth’s surface, air movement is deflected to the right in the northern hemisphere and to the left in the southern hemisphere.
This can be seen when you look at the high and low pressure cells on a weather map The air flows in a clockwise motion away from the high pressure and counter clockwise motion towards the low pressure.
The bigger the difference in air pressure between two locations, the stronger the wind will be.
