ABSTRACT: The 'Trapped-Fetch Wave Model (TFWM)', which is developed for wave prediction in north Atlantic hurricanes, is applied to typhoon cases in western North Pacific (WNP). The comparison with operational numerical ocean wind wave prediction system at Korea Meteorological Administration (KMA) is examined. In application to WNP typhoon, the TFWM has shown some advantage against typical operational spectral wave models. Even though the full spectral 3rd generation numerical wave model can provides a reliable wave field prediction, it has little value when the atmospheric model poorly predicts the location and intensity of concerned storms or tropical cyclone. The analysis of TFWM output should lead the forecaster back to a more in-depth examination of the full spectral wave model output, resulting in an improved forecast product. As a supporting guidance tool for marine forecaster, the TFWM has shown its own uniqueness and necessity. Keywords: ocean wind wave, trapped-fetch, spectral wave model, typhoon, WAVEWATCH-III |
