Sign in to searchEl Niño and El Niño Modoki
El Niño Modoki is a variant of El Niño, but the crucial difference is where the maximum warming occurs in the tropical Pacific Ocean.
El Niño (conventional or “canonical” El Niño) is a periodic warming of sea-surface temperatures (SSTs) in the central and especially eastern equatorial Pacific, extending toward the coast of South America.
Normally, strong trade winds push warm surface water towards Indonesia and Australia. During El Niño, these winds weaken, allowing warm water to shift eastward.
