The typhoon waves in shantou coastal areas: hindcasted typhoon waves and their characteristics

摘要

This article, by use of "The computation method for the typhoon wind wave in shallow water regions affected by the coast", tried to hindcast typhoon waves which influenced the coastal areas of Shantou. Together with this process, criteria of wavepattern suggested by Thompson and formulations on energy concentration degree of different wave patterns provided by Goda were adopted to calculate the mixed waves of typhoon. Compared with the date in-situ observed, the calculated results weresatisfactory. Based on the hindcasted typhoon waves of 44 years, the variations of wave heights, wave energy and principal direction during each typhoon process were obtained, and the distribution of wave energy along with direction at the moment ofmaximum wave heights was also hindcasted.
