← GeographyWhich seasonal weather consequence results when the Coriolis effect weakens?
A)Reduced coastal upwelling intensity✓
B)Increased polar vortex instability
C)Decreased mid-latitude cyclone formation
D)Strengthened equatorial current divergence
💡 Explanation
Reduced Coriolis force weakens gyre circulation, which decreases pressure gradients that drive upwelling; therefore coastal upwelling becomes less intense. Rather than the other options, the gyres are strongest near the surface because of Ekman transport.
