摘　　要：台风浪的研究对于船舶航行、避风以及港口、海洋和近岸建筑物的安全有着重要的现实意义。本文基于考虑波浪折射、底部损耗及波浪破碎等的波谱模型,在充分考虑风能量输入、白帽耗散、水深诱导以及波-波间的非线性相互作用等物理过程,对袭击广东省和福建省沿海的0601号强台风"珍珠"引起的台风浪过程进行了数值模拟计算,计算结果与云澳海洋站和遮浪海洋站的观测资料基本吻合。经分析得到了近岸台风浪场有效波高分布的变化规律,为近岸海域台风浪场模拟与预报提供了一种有效的方法,为船舶和港口的防灾减灾提供了较为重要的参考依据。It has most important realistic significance that the research of typhoon and waves to ship navigation,shelter and the safety of the port,marine and coastal buildings.In this paper,based on the wave spectrum model with the wave refraction,bottom friction and wave breaking,full considering the wind forcing input,white cap-ping,and quadruplet-wave interaction between such physical process,the waves＇ process by no.0601＂pearl＂ty-phoon,which attacked to the coast of Guangdong and Fujian provinces,is simulated.The calculated wave heights of the strong typhoon＂pearl＂are basically same to the wave observation data at Yunao ocean station and Zhelang ocean station.By analyzing the model output,we got the variation of effective wave height by the typhoon.It pro-vides a kind of effective method for the wave simulation platform.It also provides important reference for the ship and port disaster-reduction.
