Statistics of buoy-observed waves during typhoons at Taiwanese Waters from 1997 to 2008

Twelve data buoys are being operated at Taiwanese Waters in East Asia Pacific Ocean. Typhoon-induced sea-states are the main targets of measurements. In this study, ocean waves generated by typhoons from 1997 to 2008 are analyzed. Preliminary results show that the trends of increasing scale of maximum wave heights and the duration of severe sea-states during typhoons are found. In addition, extreme large wave was also recorded. All the identities show the changing of wave climate. This may bring large impacts for the coast as well as for ocean, is an un-pretermitted issue.
