Abstract: A simple approach to the estimation of representation error (RE) of sea level (?), temperature (T), and salinity (S) observations for ocean data assimilation is described. It is assumed that the main source of RE is due ...

Abstract: A simple, versatile, computationally efficient ensemble-based method for objectively designing an observation array is described. The method seeks to compute the observation array that minimizes the analysis error variance, ...

Abstract: This paper considers implications of different forms of the ensemble transformation in the ensemble square root filters (ESRFs) for the performance of ESRF-based data assimilation systems. It highlights the importance of ...

Abstract: A series of observing system simulation experiments (OSSEs) are performed for the tropical Indian Ocean (±15° from the equator) using a simple analysis system. The analysis system projects an array of observations onto the ...

Abstract: The oceanic response to imposed changes in the latitude of the subpolar westerly winds (SWWs) over the Southern Ocean is assessed in a global ocean model. The latitude changes are achieved by applying a zonally uniform ...

Abstract: A high-resolution, numerical study of an idealized western boundary current flow over variable topography is presented, with application to the East Australian Current (EAC). The results indicate that alongshelf topographic ...

Abstract: A new ensemble ocean data assimilation system, developed for the Predictive Ocean Atmosphere Model for Australia (POAMA), is described. The new system is called PEODAS, the POAMA Ensemble Ocean Data Assimilation System. ...

Abstract: The climatological current field off the coast of New South Wales, Australia, is investigated using results from a field experiment and a diagnostic, numerical modeling study. In particular, the flow dynamics are examined ...

Abstract: Sixty-day simulations of the subinertial continental shelf circulation off Oregon are performed for a hindcast study of summer 1999. In Part I, the model results are shown to compare favorably with in situ currents and ...
