摘要：

Within the Costa Norte R&D Project, a hydrodynamic climatology was constructed for the Brazilian equatorial margin. The strong incremental constraint approach of the 4DVAR scheme inserted in the Regional Ocean Modeling System was used and applied to the initial, ocean boundary, and atmospheric forcing conditions. In situ data of temperature and salinity from the EN4 Project and remote data of sea surface temperature and sea level anomalies respectively from the OSTIA and AVISO datasets were assimilated. Besides being the first data assimilation approach performed in this energetic area, it was observed that the model consistently represented the spatial and temporal variability of the main mesoscale oceanographic features in the studied region.
