Preliminary Study on Statistical Characteristics of Waves and Surges over Taiwan Waters

摘要

We here investigate the statistical characteristics of ocean waves andrnsurges over Taiwan waters by cluster and return period analysis. Thernresults of cluster analysis show the data records from neighbor stationsrnwould not be always fall into the same cluster due to the influence ofrntopography around wave stations. In addition to, the wave height of thernspecified return period is significant related to the probabilityrndistribution of the data set. Because of the extreme wave record inrnGueishandao sea area around Taiwan, the suitable probabilityrndistribution can not be well determined in this area. It would affect thernwave height analysis of the return period. We would continue the studyrnto discuss the suitable probability distribution, so as to determine thernaccurate wave height in different situations of the specified returnrnperiod.
