摘要
建立了一类非线性海气耦合波的模式,并用该模式作了解析研究,讨论了该类海气耦合波的存在条件,发现当海气耦合较强时分别存在以海洋为主导方面及以大气为主导方面的两支海气耦合波,而耦合较弱时则仅有前者存在。还求得了该模式中该类海气耦合波的椭圆余弦波解及孤立波解,并对以海洋为主导的海气耦合波的性质作了讨论,认为海气相互作用耦合也是产生大气季节内振荡的机制之一。
A coupled ocean-atmosphere model of nonlinear waves is presented An analytical study is completed and existence condition of the air-sea interaction waves in the model is discussed It is shown that there are two branches of the interaction waves; in each branch either atmosphere of ocean plays a leading role if the coupling of atmosphere and ocean is strong; there is one branch, where only ocean plays a leading role if the coupling is weak The conical wave solution and solitary wave solution are obtaind in the model and properties of the interaction waves in which ocean plays leading role are then discussed It is suggested that interaction and coupling of atmosphere and ocean are one of the reasons of introseasonal low-frequency fluctuation in atmosphere
