Abstract: Small-amplitude, transient disturbances to a steady, zonally asymmetric basic state are considered, for barotropic (or baroclinic, quasi-geostrophic) flow on a beta-plane. An explicit expression is derived for the eddy ...

Abstract: Isentropic coordinates are used to generalize to finite amplitude the celebrated theorem (1.1) of Eliassen and Palm(1961),under non-acceleration conditions. This primitive-equation result also generalizes the finite-amplitude ...

Abstract: A quadratic conservation law is derived for small-amplitude quasi-geostrophic disturbances on a wavy basic state. The law may be useful for describing the three-dimensional propagation of disturbances on time-averaged ...

Abstract: The direction of the vertically-integrated horizontal eddy flux of momentum in linear baroclinically unstable modes is investigated in a number of cases where the basic flow contains horizontal, as well as vertical, shear. ...

Abstract: Transformed Eulerian mean (TEM) equations and Eliassen?Palm (EP) flux diagnostics are presented for the general nonhydrostatic, fully compressible, deep atmosphere formulation of the primitive equations in spherical geometric ...
