摘要
本文使用带旋转项的Kadomtsev-Petviashvili(KP)方程,将X-型波作为初始条件,进一步研究地球旋转对其的影响,并简要描述了KP方程和初始X-型波的表达式以及求解KP方程的边界条件和数值方法。从已经观测得到的波-波相互作用的形态中,选择了其中出现频率较高的3种进行研究,并得出演化结果。本文的研究结果可以加深我们对内孤立波动力学的理解,对海洋资源的开发利用和国防建设具有一定的意义。
This paper uses the Kadomtsev-Petviashvili(KP)equation with a rotation term,with X-shaped waves as the initial condition,to further study the effect of Earth rotation on it.The KP equation and the expression of the initial X-shaped waves are briefly described,as well as the boundary conditions and numerical methods for solving the KP equation.From the observed forms of wave-wave interactions,three with higher frequencies were selected for research,and the evolution results were obtained,summarized and discussed.Studying the oblique wave-wave interactions of solitary waves in the ocean not only deepens our research on the dynamics of solitary waves,but also has important significance for the development and utilization of marine resources and national defense construction.
