Instead of just rushing in to the low
pressure area, the air is also forced to rotate counterclockwise around it.
Balance
of Pressure Force and Coriolis Force
But the Coriolis force acting on this circulation velocity again tries to deflect the material to the right, i.e. outward, opposing the inward force from the
low pressure.
Now
think of this as view looking down on a low pressure region
On earth the circulation velocity usually
builds up till the outward Coriolis force almost exactly balances the inward
pressure force.
