碩士 / 國立交通大學 / 土木工程學系 / 99 / The thesis is to investigate Wave-height statistics at offshore and nearshore waters around Taiwan using sea surface heights (SSH) observation of satellite altimeters. SSH data collected by ERS-2, ENVISAT-1 and JASON-1 during 2002 to 2008 were separated into monthly groups to fit possible distributions. K-Means method, which is a kind of cluster analysis, is used to group seasonal months of summer time and winter time. Probability fitting and K-means method are also applied to measured wave data at some observations established by the Harbor and Marine Technology Center.
Comparison between SSHs and observed wave heights in separated zones show that SSHs are higher than observed wave heights in common. In Taipei Harbor, SSHs are 12 times than observed wave heights. SSHs at offshore and nearshore waters around Taiwan have low correlation coefficients with corresponding observed wave heights. The paper is a prior study to connect SSHs to observed wave heights at some particular points. In further researches more data can be carried out to develop solid connection between SSHs and observed wave heights for application of ocean engineering and wave forecasting.
