A version of the coupled ocean waves WaveWatch III (WW3) model with mesoscale meteorological model BRAMS is presented. The WW3 is a model for waves forecasting. The BRAMS model is used for numerical weather prediction over South America, with horizontal resolution of 5 km. Both models are executed operationally by the CPTEC-INPE. The boundary conditions for the BRAMS model are provided by the global atmospheric circulation model of the CPTEC-INPE. The simulation with BRAMS for14/Oct/2014 generated a wind field with better agreement with the observations (satellite Metop-A, ASCAT sensor) to the coast of southeastern Brazil) than the field wind generated by the SFM model. The simulation with wind field generated by BRAMS produces higher waves than ones predicted with GFS wind field.
