| 为准确模拟“达维”台风过境期间连云港海域波浪场分布，采用Jelesnianski风场模式模拟的海面10 m风速作为波浪模式MIKE SW的驱动风场，再现1210号“达维”台风登陆连云港海域波浪变化过程。模拟计算结果表明，Jelesnianski风场模式成功复演了“达维”台风过境期间风动力变化过程，1210号“达维”台风与1209号“苏拉”台风形成明显的双台风效应；“达维”台风风暴潮期间，连云港海洋站最大风暴增水1.78 m，连云港海域风暴增水现象十分明显；利用三重网格嵌套技术，考虑实时风暴潮增水效应的台风浪模型能够较好地模拟连云港近海波浪成长过程，台风过境期间徐圩海洋站处H1/3波高最大值为3.86 m，近岸海域波高等值线分布较为密集，分布趋势与水下地形等深线基本一致，破波带以内水域衰减速度明显加快，与连云港海域属于淤泥质海岸类型的性质相吻合。 |

| Abstract: |
| In order to accurately simulate the wave field distribution in the Lianyungang sea area during Dawei typhoon transition period, 10 m wind speed above sea surface was simulated by a Jelesnianski atmospheric model. The wave mode MIKE-SW driven by the wind field simulated the wave growing process of 1210 typhoon Dawei. The simulated results show that the Dawei typhoon moving and changing processes were successfully simulated by the Jelesnianski atmospheric model, double typhoon effects were formed in combination with No.1209 Sula typhoon. During the Dawei typhoon period, the maximum water level increase by the storm surge measured in the Lianyungang marine station was 1.78 m, and this phenomenon of water level increase by the storm surge is very significant in the Lianyungang sea area. The stormy wave growth process was well simulated in the Lianyungang sea area considering triple nested grid technology and real-time storm surge water. The meximum wave height was 3.86 m in the Lianyungang ocean station. Nearshore wave height distribution contour lines were relatively dense, and the wave distribution trend and underwater topographic isobaths were basically the same. The wave height attenuation velocity quickened significantly within the surf zone. These properties conform with the nature of the muddy coast, and the Lianyungang sea area belongs to this type of coast. |
