摘要:

摘要:  基于二维温带风暴潮控制方程和动量谱平衡方程理论,建立了二维温带风暴潮与Swan波浪计算模式相结合的波流耦合数学模型,研究了波浪辐射应力对渤海湾二维温带风暴潮过程的影响,通过对发生在该区域的2次温带风暴潮过程的模拟计算,得到了波浪辐射应力作用前后的风暴潮潮流、潮位变化过程,并与塘沽验潮站实测的潮位变化过程进行对比.结果表明:波浪辐射应力对不同风暴潮过程的影响程度不同,与风应力的分布规律有关;考虑辐射应力作用的波浪与风暴潮耦合模型的模拟潮位变化过程和实测潮位变化过程较吻合,波浪辐射应力对岸线附近潮流形态的影响较明显.

Abstract:

Abstract: Based on the theory of 2-D variable zone storm surge equations and the wave action balance equation, a acoupling model combining 2-D variable zone storm surge with the SWAN wave computing model was established, and the effect of the wave-induced radiation stress on 2-D variable zone storm surge for Bohai Bay was studied. Through the simulation of two variable zone storms in this region, the storm surge current field and current process considering and not considering wave-induced radiation stress were obtained and compared with the observation from Tanggu Tide Station. The results show that in relation to the distribution of wind field, the degree of influence for different storm surge was different.The tide process from the coupling model was in good agreement with the observation, considering waveinduced radiation stress and combining  2-D variable zone storm surge with the SWAN wave computing model. The waveinduced radiation stress has a certain effect on the current field near the shoreline.

Key words: storm surge, coupling model, wind stress, waveinduced radiation stress
