Abstract

This paper presents the results obtained from an integrated modelling system in predicting typhoon-induced waves and surge in the East China Sea. The modelling system consists of the state-of-the-art climate model: MM5 and ocean current model: POLCOMS coupled with third generation wave model: ProWAM, and is used to study the interaction and transformation between the atmospheric conditions and sea states, including waves, tides and storm surge during the typhoon seasons in the East China Sea. The tropical cyclone bogussing scheme is also used within the MM5 model in order to initiate the generation and development of typhoon in the East China Sea. The POLCOMS and ProWAM models are two way-coupled to include full wave-current interaction, and are forced with surface winds and sea level pressure generated by MM5. Both MM5 and POLCOMS/ProWAM models use two-level nesting, with the computational domains centred at the area surrounding Taiwan. The modelling system is applied to Typhoon Kalmaegi, which occurred in July 2008. Detailed study of storm track, wind and pressure fields predicted by MM5, and typhoon-generated waves and surge along the Taiwan coasts predicted by POLCOMS/ProWAM, is carried out. The comparisons of model results with the observations and other published data show a reasonable agreement, although further comparisons with field measurements are required. The results also demonstrate that it is necessary to use nesting approach and high resolution grid for waves and surge to be predicted more accurately. The modelling system can also be used to assess the impact of the typhoon storms on the coasts of northern East China Sea and Yellow Sea.
