The weakened trade winds allow warmer water from the western Pacific to surge eastward, so the sea level flattens out.
Tropical weather pattern across the equator during El Niño. With a deeper thermocline and decreased westward transport of water, the sea surface temperature increases to greater than normal in the Eastern Pacific. This is the warm phase of ENSO, called El Niño.
