El nino-southern oscillation displacements of the Western equatorial pacific warm pool.
The western equatorial Pacific warm pool (sea-surface temperatures >29 degrees C) was observed to migrate eastward across the date line during the 1986-1987 El Niño-Southern Oscillation event. Direct velocity measurements made in the upper ocean from 1986 to 1988 indicate that this migration was associated with a prolonged reversal in the South Equatorial Current forced by a large-scale relaxation ofthe trade winds. The data suggest that wind-forced zonal advection plays an important role in the thermodynamics of the western Pacific warm pool on interannual time scales.
