← GeographyWhich ocean current change results when subtropical gyre intensification weakens atmospheric Hadley cell return flow?
A)Increased coastal upwelling reduction
B)Equatorial countercurrent weakening occurs✓
C)Enhanced thermohaline circulation decline
D)Subpolar gyre intensification surge
💡 Explanation
Weakened Hadley cell return flow reduces trade wind strength, decreasing the convergence which drives the western intensification and the Equatorial Countercurrent, because pressure gradients lessen; therefore the countercurrent weakens, rather than upwelling changes which are linked to different wind patterns.
