Detailed explanation-1: -Sea surface temperatures across the central and eastern tropical Pacific Ocean become cooler than usual and the thermocline moves closer to the surface – cool waters from the deep ocean are drawn to the surface as upwelling strengthens.
Detailed explanation-2: -During El Niño, the surface winds across the entire tropical Pacific are weaker than usual. Ocean temperatures in the central and eastern tropical Pacific Ocean are warmer than average, and rainfall is below average over Indonesia and above average over the central or eastern Pacific.
Detailed explanation-3: -The equatorial thermocline is an essential component of oceanic circulation and the climate system. It acts as an invisible blanket, separating the very active upper-layer water from the relatively quiet and stagnant deep water below in the tropics.
