The western equatorial Pacific warm pool (sea-surface temperatures >29�C) was observed to migrate eastward across the date line during the 1986-1987 El Ni�o-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…

Mechanism of the Zonal Displacements of the Pacific Warm Pool: Implications for ENSO
The western equatorial Pacific warm pool is subject to strong east-west migrations on interannual time scales in phase with the Southern Oscillation Index. The dominance of surface zonal advection in…
Equatorial wave sequence associated with warm pool displacements during the 1986-1989 El Niño-La Niña
In the Pacific equatorial band the zonal displacement of the eastern edge of the warm pool, subject to insignificant seasonal variations, is dominated by strong interannual variations almost in phase…
Zonal displacement of the western equatorial Pacific ``fresh pool''
The distribution of salt in the tropical Pacific Ocean and its variability are potentially important in better understanding the El Nino Southern Oscillation (ENSO) ocean-atmosphere coupled system.…
Slow Variability in the Equatorial West-Central Pacific in Relation to ENSO
Abstract Six years of upper-ocean velocity, temperature, and surface wind data collected in the west-central Pacific at 0°, 170°W reveal a slow ocean dynamical mode associated with the El…
On the Role of the North Equatorial Counter Current in Transporting Heat during a Strong El Niño
Abstract. An analysis of archived data from the Nemo 1/12th degree global ocean model shows the importance of the NECC in the development of the 1982-83 El Nino. The model results indicate that heat…
The oceanic zone of convergence on the eastern edge of the Pacific warm pool: A synthesis of results and implications for El Niño‐Southern Oscillation and biogeochemical phenomena
The eastern edge of the western Pacific warm pool corresponds to the separation between the warm, rainfall-induced low-salinity waters of the warm pool and the cold, high-salinity upwelled waters of…
Equatorial waves and warm pool displacements during the 1992–1998 El Niño Southern Oscillation events: Observation and modeling
In the equatorial Pacific, zonal displacements of the eastern edge of the warm pool represent an intrinsic manifestation of El Nino Southern Oscillation (ENSO) events, with numerous dynamical and…
Zonal Migration of the Pacific Warm-Pool Tongue during El Nino Events
Abstract Strong east (in El Nino period)–west (in La Nina period) migrations of the western equatorial Pacific warm-pool tongue are discussed from the viewpoint of extrusion and disintegration of the…
Biological‐physical coupling in the Central Equatorial Pacific during the onset of the 1997–98 El Niño
Perturbations to phytoplankton biomass associated with the onset of the 1997–98 El Nino event are described and explained using physical and bio-optical data from moorings in the central equatorial…
Wind Stress Variations and Interannual Sea Surface Temperature Anomalies in the Eastern Equatorial Pacific
Abstract Vertical advection of temperature is the primary mechanism by which El Nino–Southern Oscillation (ENSO) time-scale sea surface temperature (SST) anomalies are generated in the eastern…
