| 摘要: |
| 采用海浪模式(Simulating Waves Nearshore, SWAN)与风暴潮模式(Advanced Circulation Model,ADCIRC)的耦合模式, 模拟研究了2011 年第11 号超强台风南玛都期间, 风暴潮对海浪的影响。通过对比耦合模式和非耦合模式模拟结果, 发现对于该超强台风过程, 台风中心附近的大浪区内风暴潮对海浪有显著影响: 在台风中心沿前进方向的右前方, 风暴潮使海浪波高减小; 在台风中心和台风中心的左后方, 风暴潮使海浪波高增大。台风进入台湾海峡之前, 风暴潮对海浪波高的最大影响为10%左右; 进入台湾海峡后, 受地形和潮汐潮流的影响, 海浪波高受到的最大影响增大到25%左右。上述结果对台风期间的海浪模拟有一定参考价值。 |

| Abstract: |
| We studied the effect of surge on waves during super typhoon Nanmadol in 2011 using a coupled wave-surge model built with a wave model (Simulating Waves Nearshore, SWAN) and a surge model (Advanced Circulation Model, ADCIRC). Comparison of results between coupled and uncoupled models showed that, during this typhoon period, the effects of surge on waves are concentrated within the radius of maximum wind. Surge decreased wave height in the right-front quarter of the typhoon center and it increased wave height in the left-rear quarter and typhoon center. Before crossing Taiwan Island, the influence range of surge on wave heights was about 10% based on the uncoupled model result, and after entering Taiwan Strait, the range expanded to about 25% because of the topography and strong tide. This study is a reference for wave simulation. |
