| 摘 要： | 基于弱二维的KP方程，并结合南中国海东沙群岛附近内孤立波的观测资料，模拟了内孤立波的波-波相互倌用0数值结果较好的反应了内孤立波的二维特征，同时体现两个内孤立波波-波相互作用的非线性特征，即两波相交处相速随振幅的增大而变大。相比于一维的KdV方程，KP在内孤立波的仿真反演方面具有更大的优势。

| Abstract: | Combined with the observation data on internal solitary waves near the Dongsha Island in the South China Sea(SCS),a numerical simulation on the wave-wave interaction is internal solitary wave conducted based on the KP equation.The numerical results successfully reflect the two dimensional character of the internal solitary waves.Nonlinear properties of the wave-wave interaction process are modeled,i.e.,the phase velocity increases with the increase of the wave amplitude.Compared with the KdV equation,the KP equation has significant advantage in modeling the two dimensional character of internal solitary waves. |
