| Descripción: | Two numerical wave models were evaluated in extreme wind conditions: a deep-water wave model, WAVEWATCH III, and a shallow water wave model, SWAN. The general objective of the research is to assess the performance of these two spectral wave models to represent the wave height under hurricane conditions with two kinds of wind models: parametric and dynamic. Four experiments were conducted with major historical hurricanes that crossed the Gulf of Mexico (Lili 2002, Ivan 2004, Rita 2005, and Gustav 2008). In order to compare results from the models, in-situ data of wind speed and significant wave height was obtained from the National Data Buoy Center and evaluated using statistical parameters. Results showed that, by using the parametric wind field model in SWAN and WAVEWATCH III, both models tend to represent the peaks of observed significant wave height when the storm path passes close to the measuring buoy (< 400 km). Forced by the wind field of the WRF model, WAVEWATCH III tends to underestimate the peak wave height. The evaluated statistics and the time series of wind speed and wave height show that, forced by the HURWIN parametric model, SWAN and WAVEWATCH III are adequate for wave simulation under major hurricane conditions. |
