摘要：wave fields in Beibu Bay during Typhoon Damrey （2005） were simulated by SWAN wave model through inputting high resolution reanalysis wind fields data, current and water level data. Comparisons for wind input and wave hindcast between observation and simulation show good consistency. Distributions of wave parameters such as wave height, wave period, wave length and wave direction under typhoon wind forcing were given. Also, the directional spectra related to the different position from the typhoon center were discussed. And at last, the variation and characteristics of observed frequency spectrum during the passage of Damrey were presented.
