Detailed explanation-1: -An El Niño condition occurs when surface water in the equatorial Pacific becomes warmer than average and east winds blow weaker than normal. The opposite condition is called La Niña. During this phase of ENSO, the water is cooler than normal and the east winds are stronger. El Niños typically occur every 3 to 5 years.
Detailed explanation-2: -So, we could conclude that from the given examples, the one that is not true of an El Niño– Southern Oscillation (ENSO) event is : It causes increased upwelling on the coast of South America.
Detailed explanation-3: -The lack of El Niño or La Niña means that there is no seasonal-scale influence from the Pacific to push around the global atmospheric circulation and influence seasonal climate patterns.
