Abstract: The low-level jet which flows across the equator and up the Somali coast is considered as a western boundary current of the East African mountain chain. The jet is assumed to be forced by the low-level divergence in the ...

Abstract: A four-dimensional variational method is used to examine the extent to which a time sequence of altimeter measurements can determine the subsurface flow in a linear multilayer model of the tropical Pacific Ocean. The ...

Abstract: In a previous study Anderson and Corry used a wind-driven two-layer model to study the effects of topography and islands on the seasonal variation of western boundary currents. The work is continued here with topography, ...

Abstract: The relative information content of mass and velocity measurements for initializing low-frequency equatorially trapped waves is considered using analytical arguments and a numerical model For the Kelvin wave, mass and ...

Abstract: A linear reduced-gravity model of the tropical pacific is used to assimilate XBT data. The model cannot fit the data in the eastern equatorial Pacific for the whole assimilation period. Several experiments with real and ...

Abstract: A variations method based on the adjoint equation technique is used to assimilate data in a relatively simple linear reduced gravity model of the tropical Pacific. Real XBT data are used by identifying the depth of the ...

Abstract: Solutions to a coupled atmosphere model are discussed. The model ocean is a generalization of a reduced-gravity model that includes an equation for the temperature of the layer T. The model atmosphere is linear, baroclinic, ...

Abstract: A model of tropical ocean-atmosphere interaction is used to study the El Niño?Southern Oscillation phenomenon. The model ocean consists of the single baroclinic mode of a two-layer ocean. The thermodynamics of the upper ...

Abstract: The coupled ocean-atmosphere model of Anderson and McCreary is extended to include two oceans. An advantage of the two-ocean system is that it is not necessary to specify externally convection over land. For a basin geometry ...

Abstract: A new operational ocean analysis/reanalysis system (ORA-S3) has been implemented at ECMWF. The reanalysis, started from 1 January 1959, is continuously maintained up to 11 days behind real time and is used to initialize ...
