Which global climatic anomaly, characterized by sustained abnormal cooling of surface waters in the central and eastern tropical Pacific Ocean, often correlates with enhanced monsoon rainfall and flood events in Kerala?
A. El Niño
B. La Niña✓ Correct Answer
C. Pacific Decadal Oscillation
D. North Atlantic Oscillation
💡 Solution & Explanation
La Niña events involve the abnormal cooling of sea surface temperatures across the central and eastern tropical Pacific, which strengthens monsoon winds and frequently brings heavy rainfall to southern India. Conversely, El Niño is associated with warming surface waters and often causes deficient monsoon rainfall. These oscillations form part of the El Niño-Southern Oscillation climate cycle.
