Pressure Gradient Force
directed from high to low pressure

The change in pressure measured across a given distance is called a "pressure gradient".

The pressure gradient results in a net force that is directed from high to low pressure and this force is called the "pressure gradient force".

The pressure gradient force is responsible for triggering the initial movement of air.
