???? Force Balance in a Low

  • P (PGF) and C (centripetal force) are both directed inward toward the center of the low.

  • The Coriolis force (f) acts outward, trying to push air away from the center.

So to maintain circular motion:

  • The inward forces (P + C) must balance the outward Coriolis force (f).

But wait — centripetal force isn’t an independent force; it comes from the curved path of the air and is provided by part of the pressure gradient.

???? Key Idea:

  • Part of the pressure gradient (P) goes into creating the necessary curvature (C), and only the remaining part of P balances the Coriolis force (f).

  • So, effectively, P < f when you look at how much of the pressure gradient is left to balance the Coriolis force.

Now, since:

  • Coriolis force increases with wind speed

  • And we have P < f

This means the wind speed (V) must be less than what it would be if only P and f were balancing each other — that is, the geostrophic wind speed.
