← GeographyWhich climate consequence results when trade winds weaken significantly during an El Niño event?
A)Increased coastal upwelling off Peru
B)Cooler sea surface temperatures in western Pacific
C)Enhanced coral reef growth in Australia
D)Increased rainfall in the eastern Pacific✓
💡 Explanation
When trade winds weaken during El Niño, warm water normally piled up in the western Pacific surges eastward because wind forcing decreases, resulting in increased rainfall in the eastern Pacific. Therefore it is option D, rather than upwelling, cooler temperatures, or enhanced coral growth which require stronger trade winds or different oceanic conditions.
