Refraction occurs in the domain of inhomogeneous ocean depth; the shallower the ocean, the obvious the topography effect. When internal wave propagates to the continental shelf, the direction of the IWs is changing perpendicular to the isobath.
海底地形和海洋水深的变化影响内波的传播,地形的变化使得内波的传播方向发生折射;水深越浅,地形效应越明显;内波在传播到陆架海区后,水深的变浅使得波峰线有向平行于等深线方向传播的趋势。
