Question

what is mean by pressure gradient force? What is its contribution in air movement ​

Answer 1

Answer:

The change in pressure measured across a given distance called a Pressure Gradient. The pressure gradient creates a net force that is directed from higher to lower pressure and is called the Pressure Gradient Force. ... As air increases in velocity, it is deflected by the Coriolis Force.

Answer 2

Pressure gradient is a physical quantity that tells us the rate of increase in pressure and its direction around a specific location.

Explanation:

• Pressure gradient force is the force that results because of difference of pressure across a surface.

• 'Pressure gradient force' is responsible for the movement of air. At sea-level air is warmer and has lower pressure while air at poles is colder and has higher pressure.

• These difference in pressure causes air to move from areas of low pressure to high pressure.
