Abstract

In this theoretical paper, Eady's linear model of baroclinic instability of a zonal basic flow of an inviscid non‐conducting Boussinesq fluid in quasi‐geostrophic motion is extended by consideration of non‐linearity. The method of normal mode cascade is used to find the non‐linear development of a slightly unstable linear disturbance. Amplitude vacillations are found, similar to some observed in experiments on a differentially‐heated rotating annulus. Interactions of the zonal flow and non‐linear waves are described analytically and related to instability of the westerlies in mid‐latitudes.

AbstractPInstability of the interfaw for two phase pipe flow and transition from stratified Row to slug or annular flow is considered a long wave phenomenon. Kelvin-Helmholtz (KH) analysis is usually used for analyzing the stability of the interface. Two types of linear stability analyses have been
