Which of the following is not a feature of El Niño Southern Oscillation (ENSO)?

Reversal of Westerlies
ENSO results in reversal of trade winds not westerlies. A periodic disruption of normal sea surface and atmospheric circulation patterns in the Pacific Ocean is called El Niño Southern Oscillation (ENSO). The warm phase of ENSO (El Niño) is associated with the eastward movement of the Pacific warm pool, halting or reversal of the trade winds, a rise in sea level along the equator, a decrease in productivity along the west coast of South America, and, in very strong El Niños, worldwide changes in weather. El Niños fluctuate with the cool phase of ENSO (La Niña conditions), which are associated with cooler than normal water in the eastern tropical Pacific.
