The pressure gradient force (Pgf) is a force that tries to equalize pressure differences. This is the force that causes high pressure to push air toward low pressure. Thus air would flow from high to low pressure if the pressure gradient force was the only force acting on it. How the coriolis force works on a rotating disk. However, because of the earth's rotation, there is second force, the Coriolis force that affects the direction of wind flow.
Wind is caused by air flowing from high pressure to low pressure. The Earthâs rotation prevents that flow from being direct, but deflects it side to side(right in the Northern Hemisphere and left in the Southern), so wind flows around the high and low pressure areas. This movement around is important for very large and long-lived pressure systems.
