← GeographyWhich mechanism significantly influences the prevailing wind direction in mid-latitude cyclones due to the Coriolis effect?
A)Ekman transport redirects surface currents.
B)Geostrophic balance shapes pressure gradients.✓
C)Orographic lift enhances precipitation rates.
D)Thermal inertia moderates temperature fluctuations.
💡 Explanation
When air flows towards a low-pressure center in mid-latitudes, the Coriolis effect induces a deflection balanced by the pressure gradient force, a state called geostrophic balance, resulting in spiraling wind patterns. Therefore, geostrophic balance shapes pressure gradients rather than current transport, orographic effects, or thermal inertia, requiring different geographic mechanisms.
