Application of a perturbation technique to the nonlinear equations of internal wave motion

摘要: Isotherm-follower traces that demonstrate the effect noted by LeFond and Lee are shown, is, with flattening of internal wave crests when thermocline is shallow spiking was near ocean bottom. Also, a isotherm field in deep water as considered. The isotherm-follower showing importance higher harmonics analyzed. A simplified two-layer model constructed, perturbation expansion performed to obtain second-order correction profile. Numerical methods employed compare derived profiles observed profiles, good agreement shown. profile also exhibits phenomenon. shoaling hypothesized from expression.
