基于Korteweg-de Vries方程解析解的海洋内波模拟研究

摘要

Utilizing the abundant analytical soliton solutions of nonlinear evolution equation, the propagation characteristics of the internal waves in the northeast of Taiwan in the East China Sea have been investigated based on the Korteweg-de Vries equation including the dissipative and perturbed terms. In a two-layer ocean system, the variation of signature characteristics for the internal wave on SAR image have been discussed. The effects of dissipative and perturbed terms on internal waves and horizontal velocity of the ocean surface current has been presented.%主要是利用非线性发展方程丰富的解析解,基于含有散射项和微扰项的Korteweg-de Vries方程对台湾东北部东海海域内波的传播特性进行研究,并着重分析海洋内波在SAR图像上的信号特征,进而讨论耗散项和微扰项对海洋内波所引起的表层流速变化的影响.
