South Korea typically experiences one or two typhoons per year in the surrounding waters of the Yellow Sea and East China Sea. The intensification of typhoons often leads to significant coastal disasters caused by extreme waves in the region. This study presents an analysis of space-time wave extreme parameters, including maximum crest and wave height, using the spectral wave model WAVEWATCH III (WWIII) in the typhoon event. Wind data from ERA-5 reanalysis has been employed as the forcing field in the model. To assess the model's performance, simulations were compared with observational data during Typhoon Hinnamnor on September 4-6, 2022, using a stereo camera system installed on the Gageocho Ocean Research Station, an offshore platform in the Yellow Sea, southwest of South Korea. The results indicate that the spectral shapes and simulated space-time wave extremes have been found in fair agreement with observed data. However, some discrepancies primarily arise from inaccuracies in the wind forcing during the experiment.
