摘要: 对于考虑旋转向量水平分量的大洋内波方程,本文求出了满足该方程的波函数的一个渐近解.该渐近波函数的振荡特性得到研究,结果表明旋转向量水平分量对高模态(高波数)内波的影响是不可忽略的.Abstract: To the equations for oceanic internal waves under considering the horizontal component of the rotation vector,an asymptotic solution of the wave functions satisfying these equations is found.The oscillation characteristics of the asymptotic wave functions are studied.The results of research show that the effect of the horizontal component of the rotation vector on the high mode (the high wavenumber) internal waves in the ocean cannot be neglected.
