ВАЛИДАЦИЯ МОДЕЛЕЙ ВЕТРОВОГО ВОЛНЕНИЯ WAVEWATCH III И SWAN ПО ДАННЫМ НАТУРНЫХ И СПУТНИКОВЫХ НАБЛЮДЕНИЙ

Abstract

In this study, the state-of-the-art third generation spectral wave models WAVEWATCH III and SWAN have been used to predict waves for the Barcelona Bay (Spain) and for the south shoreline of the Mediterranean Sea (Algerian coast). We used two different nesting strategies in order to reach the local scale, the one-way and two-way nesting systems down method for the period from January to March 2017. The wave models were forced by the hourly wind data from the CFSR (CFSv2) global atmospheric model and by the hourly current from the hydrodynamic model NEMO during the simulation period. The high-resolution wave parameters (mainly significant wave height (SWH)) were compared to in situ buoy and altimeter data. At shallow water, results suggest that WW3 and SWAN nested grids describe variability of wave parameters, mainly the SWH, with good accuracy. With regional data remotely sensed along track altimeter, results showed that SWH at the WW3 nested grid is in good agreement with SARAL and Jason-2 data. Both nesting systems can be used as a platform to provide accurate, high-resolution coastal forecasts.
