Discussion
Balance of forces and different types of flows/weather phenomena in the northern hemisphere are given. Match the following:
| Balance of forces | Flow type/weather phenomena | ||
|---|---|---|---|
| P | Balance between pressure gradient force, centrifugal force and Coriolis force in anticlockwise rotation | X | Geostrophic flow |
| Q | Balance between pressure gradient force and centrifugal force in clockwise/ anticlockwise rotation | Y | Cyclones |
| R | Balance between pressure gradient force and Coriolis force in a uniform flow | Z | Tornado |
Answer: C
The correct matching is P - Y; Q - Z; R - X.
- A balance of pressure gradient, centrifugal and Coriolis forces in curved flow is the gradient wind; anticlockwise rotation in the Northern Hemisphere is cyclonic, so P describes cyclones (Y).
- A balance of pressure gradient and centrifugal force alone is cyclostrophic flow, found in small, intense vortices where the Coriolis force is negligible and either sense of rotation is possible: tornadoes (Q-Z).
- A balance of pressure gradient and Coriolis force in straight, uniform flow is geostrophic flow (R-X).
The other options assign geostrophic flow to curved or cyclostrophic balances, or tornadoes to the gradient balance, which mismatch the forces involved.
