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、波浪破碎以及波-波间的非线性相互作用等物理过程后,对在福建省中部登陆的0513号"泰利"、0709号"圣帕"和0808号"凤凰"台风引起的台风浪过程进行了数值模拟计算。计算结果与实测数据相吻合,并总结出闽中近岸西北行路径台风浪的波向变化规律。为近岸海域船舶航行和港口工程防灾减灾提供了较为重要的参考依据。Study on the typhoon wave has an important practical significance for ship navigation and shelter, as well as the safety of ports, marine and coastal buildings. In the paper, the spectral model, considering wave refrac- tion, bottom friction and wave breaking, is used. After taking full account of the wind energy input, white cap- ping dissipation, wave breaking, nonlinear interactions between waves and other physical processes, we have con- ducted numerical simulations for the processes of typhoon waves by No. 0513 ＂Talim＂, No. 0709 ＂Sepat＂ and No.0808 ＂Fung-Wong＂ which landed in the middle coast of Fujian Province. The calculated results are in a good agreement with the measured data provided by the Forecasting Center of East China Sea. Meanwhile, we summa- rized the pattern of the northwest typhoon wave direction characteristics in the offshore of Fujian Province, which can provide an important reference for ship navigation in the offshore area, disaster prevention and mitiga- tion of port engineering.
