为研究西北行路径的台风登陆前近岸台风浪的变化规律，依据MIKE21 SW谱波浪模型建立了浙江省近岸台风浪模型，对西北行路径台风浪进行数值模拟，计算结果与实测数据基本吻合。在此基础上统计分析了台风移动路径上及其左右两侧台风浪的变化规律。结果表明：台风移动路径上前眼壁处有效波高最大，后眼壁处次之；台风眼中心区域有效波高经历着无规律的衰减过程；台风移动路径两侧的有效波高与该点到台风移动路径的距离成反比，当与台风移动路径的距离最小时，有效波高达到最大值；而右侧的有效波高比左侧的有效波高大，其增幅可达29%~48%。本研究结果可为近岸台风浪预报和渔船选择回港避风路径提供参考依据。

A wave model in the outward sea of Zhejiang coast was established by simulation of the northwest moving path typhoon based on spectrum wave model in MIKE21-SW, and compared with the data from surveying station to evaluate the change in northwest offshore typhoon waves before the typhoon landed. The results showed the typhoon waves changing in the typhoon moving path and two sides of the moving path, the maximum significant wave height on the typhoon moving path in front of the typhoon eye wall, followed by at the back of the typhoon eye wall. The significant wave height on both right and left sides of typhoon moving path was found to be inversely proportional to distance, the maximum wave height at the shortest distance. The right wave height was higher than the left one, in-crease by 29%-48%. The findings provided a reference for disaster prevention and mitigation for offshore typhoon waves forecasting and for ships back to harbor.
