摘要

This report provides the results of a series of validation experiments that compare the prediction accuracy and efficiency of the Navy Coastal Ocean Model Four-Dimensional Variational Assimilation (NCOM 4DVAR), version 1.0, relative to the current, operational version of the Relocatable (Relo) NCOM. The NCOM 4DVAR uses the more advanced representer-based 4DVAR method to compute analyses. The validation experiments include the application of NCOM 4DVAR in nine regional domains. Three of these experiments were performed in the Okinawa Trough, the U.S. East Coast, and the Northern Arabian Sea in an operational mode on the Operational Oceanography Center (OOC). Overall, the validation results reveal that the applications of NCOM 4DVAR have improved performance in terms of reduced average Root Mean Squared (RMS) errors for temperature and salinity analyses and forecasts when compared to similar applications of the operational Relo NCOM system.
