← GeographyWhich outcome results when increased greenhouse gasses diminish trade wind strength?
A)Increased eastern Pacific upwelling intensity
B)La Niña-like conditions become prolonged
C)Enhanced thermocline in western Pacific
D)More frequent intense El Niño events✓
💡 Explanation
Weaker trade winds reduce normal equatorial upwelling which diminishes the east-west sea surface temperature gradient, and the weakened Walker circulation brings on El Niño, triggered by this wind-thermocline interaction. therefore stronger EI Niño events occurs rather than La Niña intensification under these conditions.
