← GeographyWhich effect results when intensifying trade winds strengthen the subtropical gyres in the Pacific Ocean?
A)Increased coastal upwelling along continents
B)Decreased equatorial sea surface temperatures✓
C)Weakened thermocline in the central Pacific
D)Enhanced formation of sea ice at poles
💡 Explanation
When trade winds intensify, Ekman transport increases because surface water is deflected offshore, causing deeper, colder water to rise, reducing temperatures. Therefore, decreased equatorial sea surface temperatures result, rather than stronger upwelling, a weakened thermocline, or increased sea ice which require different conditions.
