Abstract:

Ocean wave characteristics in the western Atlantic Ocean Hurricane Region to tropical cyclones have been investigated extensively, but not the regional seas in the western Pacific such as the South China Sea Typhoon Region. This is due to the lack of observational and modeling studies in western Pacific regional seas. To fill this gap, Wavewatch-III WW3 is used to study the response of the South China Sea SCS to Typhoon Muifa 2004. The WW3 model is integrated from the JONSWAP wave spectra Hasselmann et al. 1973, 1980 using NASA Quikscatter winds and tropical cyclone wind profile model during Typhoon Muifa passage from 0000UTC 16 on November to 1200UTC on 25 November 2004. This study shows strong similarities in the responses between Hurricane and Typhoon Regions, including strong asymmetry in the significant wave height Hs along the typhoon translation track with the maximum Hs in the right-front quadrant of the typhoon center, and asymmetry in the directional wave spectra at different locations frontward, backward, rightward, leftward around the typhoon center. The unique features of the SCS wave characteristics to Muifa are also discussed.
