Abstract: The trade winds over the central Pacific are observed to weaken several months after the appearance of anomalously warm surface waters in the eastern equatorial Pacific Ocean. The following results obtained with a numerical ...

Abstract: Because of the narrow region over which it has high speeds, the Equatorial Undercurrent has little effect on long waves with large phase speeds, such as long Kelvin and equatorially trapped inertia-gravity modes with ...

Abstract: Nonlinearities weaken westward equatorial jets and cause them to be shallower and broader than their linear counterparts. Nonlinear eastward equatorial jets, on the other hand, are more intense, deeper and narrower than ...

Abstract: El Niño and La Niña are the two complementary phase of the Southern Oscillation. During E1 Niña, the area of high sea surface temperatures increases, while the atmospheric convection zones of the tropical Pacific expand ...

Abstract: The Southern Oscillation, an irregular interannual fluctuation between warm El Niño and cold La Niña conditions that has its largest amplitude in the tropical Pacific, is attributable to interactions between the ocean and ...

Abstract: Although the winds on the equator at 28°W in the Atlantic and 140°W in the Pacific have similar seasonal variations, the current fluctuations have pronounced differences. In the Pacific the maximum speed of the Equatorial ...

Abstract: A realistic oceanic general circulation model is forced with winds observed over the tropical Pacific between1967 and 1979. The structure of the simulated Southern Oscillation is strikingly different in the western andeastern ...

Abstract: Wavelet transforms, which can unfold signals in both time and frequency domains, are used to analyze the Comprehensive Ocean and Atmospheric Data Sets for the period 1870?1988. The focus is on secular changes in the ...

Abstract: Measurements indicate that mixing processes are intense in the surface layers of the ocean but weak below the thermocline, except for the region below the core of the Equatorial Undercurrent where vertical temperature ...

Abstract: An oceanic GCM is used to investigate the response of the tropical and subtropical thermocline circulation and structure to different wind stress patterns. Although the subtropical winds do not affect the transport or the ...
