Abstract

Based on long-term wave measurements in the northern sea area of Jiangsu Province, this study statistically analyzed four typhoon events and six cold wave processes to investigate wave characteristics under extreme weather conditions. The results demonstrate that the maximum wave heights induced by typhoons and cold waves are comparable, with significant wave heights reaching 4.59 and 4.73 m respectively. The typhoon waves generated by landfall typhoons are much greater than those of non-landfall typhoons. A positive correlation is observed between wave height and period during extreme wave events, and the wave spectrum is mainly single-peak spectrum, and both wind waves and swell waves exist.

Key words

wave spectra / wind sea / swell / typhoon wave / cold wave / northern sea area of Jiangsu
