本文采用 ECOMSED 模式模拟了影响东中国海的 3 次台风过程,经与实测资料对比验证了模型的可靠性.在此基础上设计了敏感性试验以考察海平面上升对风暴潮造成的影响.结果表明,海平面上升对风暴潮的影响在空间分布上不是一致的,且因具体台风过程而异.整体而言,海平面上升对风暴潮造成的影响有限.海平面上升 0.5 m,大部分站位风暴增水极值基本不变,即使海平面上升 5 m大部分站位的风暴增水极值相对改变量都小于 10 %.

In this paper,ECOMSED (Estuarine Coastal Ocean Model with sediment transport) model is employed to simulate storm surge process caused by typhoon passing across East China Sea in nearly years.Capability of ECOMSED to simulate storm surge is validated by comparing model result with observed data.Sensitivity experiments are designed to study the influence of sea level rise on typhoon storm surge.Numerical experiment shows that influence of mean sea level rise on typhoon storm surge is non-uniform spatially and changes as typhoon process differs.Maybe fixed boundary method would weaken the influence of mean sea level rise on storm surge,and free boundary method is suggested for the succeeding study.
