pressure gradient force
The pressure gradient force is the movement of air from areas of high pressure to areas of low pressure. It acts perpendicular to the lines of equal pressure, called isobars, and is responsible for initiating wind. The stronger the difference in pressure between two areas, the greater the force and the faster the air will move. This force is fundamental in weather patterns, as it drives air flows that influence wind speed and direction, shaping climate and weather systems across the globe.
