A Three-Way Comparison of Sea Level from the Central Equatorial Pacific, 1985-89

Abstract

Temporal and spatial features of central equatorial Pacific Ocean sea-level variation appear similar, in measurements from two very different systems (one in the ocean and one carried on a satellite), and in results from a numerical model of the region. In particular, there is an interannual cycle: during El Nino, Kelvin waves appear at the equator, and the sea-surface ridge associated with the equatorial current system shifts southward; in non El Nino years, instability waves appear at 690N, and the ridge shifts to the north. This three-way comparison gives support both to measurement systems and to the numerical model.... Ocean models, Ocean forecasting, Fronts(Oceanography)
