| 摘 要： | 台风过程期间,风暴潮和海浪是相伴相生的,相互作用的.波致辐射应力对于近岸风暴增、减水起着十分重要的作用,传统的海浪模式计算辐射应力耗时较多,不能满足业务化预报的要求.根据已有波浪辐射应力的理论表达式,经过严密的数学推导,适当的简化处理,提出了一个较为简单的波浪辐射应力表达式,并将其应用到业务化风暴潮数值预报模式中去,通...

| Abstract: | During the process of typhoon, storm surges and waves are concomitant and interact with each other. Wave-induced radiation stress plays an important role on the nearshore.To get correct radiation stress, storm surge. The traditional 3rd generation sea wave model is time-consuming and can not meet the requirements of operational forecasting. On the basis of primitive expression of wave-induced radiation stress,a simplified radiation stress expression is deduced and can be easily added to the storm surge model. A practical storm surge model including the role of wave set-up in nearshore waters is proposed. The new model can not only improve the physical process of wave set-up and time-saving, but also obtain a more satisfactory result than the old one through two disastrous storm surge's simulation in Guangdong coastal areas. |
