基于流-浪-潮耦合的风暴潮二维模式,建立上海海域风暴潮模型。通过历史上5次典型台风风暴潮的后报验证,证实该模型适用于上海海域风暴潮增水预测。对近年影响上海较为严重的1211号台风“海葵”风暴潮进行数值模拟,分析其实际条件下以及模拟不同登陆条件时对上海沿海可能出现的风暴潮过程及最大增水,该结果对保障上海的防汛安全具有实际意义。
Based on the two-dimensional model of storm surge induced by flow-wave-tidal coupling, a model of storm surge in Shanghai area is established. After five typical typhoon storm surges in history, the model was verified to be suitable for forecasting storm surge in Shanghai area. The numerical simulation of 1212 typhoon “Anemone” storm surge which affected Shanghai in recent years was carried out. The possible storm surge process and maximum water increase in Shanghai coastal area under actual conditions and simulated different landing conditions were analyzed. It is of practical significance to ensure the flood control safety in Shanghai.
