Abstract
Numerical analysis of wind-waves generated by tropical cyclones using the WAve Model Cycle 4 (WAMC4) was studied. The WAMC4 model was enabled to study the impacts of surface waves generated by tropical cyclones under the open sea condition in the Gulf of Thailand (GoT). In this study, the WAMC4 model was used to calculate the severe storm waves under the forcing fields of tropical cyclone winds which were simulated by the available U.S. Navy Global Atmospheric Prediction System (NOGAPS) model. The WAMC4 model was also applied to calculate the impacts of storm waves in cases of Typhoon Linda (1997), Typhoon Muifa (2004) and Super Typhoon Durian (2006). The impacts of severe storm waves along the best tracks of those typhoons were considered from the model results and also the data obtained from the Joint Typhoon Warning Center (JTWC). The results of the WAMC4 model indicated that the severe storm wave generated by Typhoon Linda is the only one affecting Thailand, while Typhoon Muifa and Durian weakened when they approached the GoT resulting in decreasing the wave heights and their intensities. ฉ 2011 ASCE.
