Answer & explanation

The correct statement about El Niño is: Refers to abnormal warming of surface waters in the equatorial Pacific Ocean
- El Niño is characterized by unusually warm sea surface temperatures in the central and eastern equatorial Pacific.
- It usually suppresses Indian monsoon rainfall (so option about aiding rainfall is wrong).
- It does not cause cooling, so the cooling option is wrong.
- High temperatures in the Western Pacific and Indian Ocean are not directly caused by El Niño; the warming is mainly in the central and eastern Pacific.
