| 摘要: |
| 台风浪灾害在山东半岛沿海时常发生，对人类生命财产和基础设施构成很大威胁，因此，对山东半岛海域台风浪的危险性分析具有重要的现实意义。本研究使用ADCIRC+SWAN耦合数值模式采用Holland模型风场与NCEP再分析风场组合的风场驱动，对1979—2018年36次台风过境期间的海浪过程进行了模拟。以台风过境时最大有效波高及历时频数作为危险性评价指标，给出了山东半岛近岸台风浪强度等级分布、历时频数分布以及危险性指数分布。研究结果显示，山东半岛北部为台风浪低危险区，台风浪强度等级低且历时短；南部二级强度（有效波高范围为1.3—2.5m）以上台风浪发生较为频繁，危险性高于北部；东部台风浪强度可以达到四级（有效波高4m以上），危险性最高。 |

| Abstract: |
| Typhoon waves often occur at different levels near the coast of Shandong, posing a great threat to human life, property and infrastructure. Therefore, it is of great practical significance to analyze the risk of typhoon waves in Shandong Peninsula. In this study, the ADCIRC+SWAN coupled numerical model is used to simulate the wave process during the passage of 36 typhoons from 1979 to 2018, which is driven by the combination of Holland model wind field and NCEP reanalysis wind field. Taking the maximum significant wave height of typhoon as the risk evaluation index, the distribution of typhoon wave intensity, duration frequency and risk index in Shandong Peninsula are given. The results show that the northern part of Shandong Peninsula is a low risk area for typhoon waves, with low intensity and short duration; In the south, typhoon waves above the level 2 intensity (the significant wave height range is 1.3-2.5m) occur more frequently, and the risk is higher than that in the north; The intensity of typhoon wave in the east can reach level 4 (the significant wave height is above 4m), and the risk of typhoon wave in this area is the highest. |
