Which consequence results when ocean temperatures rise above a critical threshold during El Niño?

💡 Explanation

Reduced upwelling occurs because thermal stratification intensifies, therefore inhibiting vertical Water column mixing, rather than the opposite; upwelling depends on density differences caused by temperature and salinity, not direct changes in winds alone.
