Assimilation of Geosat Altimetric Data in a Nonlinear Reduced-Gravity Model of the Indian Ocean. Part 1：Adjoint Approach and Model-Data Consistency
Geosat Altimetric Data Nonlinear Reduced-Gravity Model Indian Ocean Model-Data Consistency

Geosat sea-level variations are assimilated into a nonlinear shallow-water model of the Indian Ocean. After spinup, the model forced by observed winds over 1985–1988 provides a first guess for initial...
Successive Correction of the Mean Sea Surface Height by the Simultaneous Assimilation of Drifting Buoy and Altimetric Data
Sea Surface Height Altimetric Data Drifting Buoy

A simultaneous assimilation model of drifting buoy and altimetric data is proposed to determine the mean sea surface height (SSH) as well as the temporal evolution of the surface circulation on synopt...

This paper examines the results of assimilating Geosat sea level variations relative to the November 1986–November 1988 mean reference, in a nonlinear reduced-gravity model of the Indian Ocean. Data h...

Low-frequency variability of western boundary currents (WBCs) is pervasive in both observations and numerical models of the oceans. Because advection is of the essence in WBCs, nonlinearities are thou...
