Abstract

The lack of adequate observational information over the ocean, create a great difficulty in prediction of ocean state near the Indian coasts. Frequent satellite passes over this region provides valuable wind data resources that can be used to force regional models to evaluate ocean wave spectrum near coasts with a better accuracy. In this work both scatterometer wind from QuikSCAT as well as the ETA model wind from NCMRWF are used to force coastal wave model SWAN nested in open-ocean WAM model. The results indicate that the SWAN nested in WAM predicts the wind generated wave height with better accuracy when forced when forced with the QuikSCAT wind. But the swell height predominantly depends on the boundary conditions provided on the model.
