Kelvin Helmholtz（KH）问题，零分层，检查作为一个单一的剪切层的宽度趋于零的瑞利模型的极限情况。过渡的瑞利模态色散关系的KH的，以及消失的超模态瞬态增长的KH极限，都是合理化的反向传播Rossby波的角度来看。
The Kelvin Helmholtz (KH) problem, with zero stratification, is examined as a limiting case of the Rayleigh model of a single shear layer whose width tends to zero. The transition of the Rayleigh modal dispersion relation to the KH one, as well as the disappearance of the supermodal transient growth in the KH limit, are both rationalized from the counterpropagating Rossby wave perspective.
