Reexamining the Dynamics of Short-Scale, Diabatic Rossby Waves and Their Role in Midlatitude Moist Cyclogenesis

Abstract

As a step toward a more comprehensive study of the physical processes that underlie explosive cyclogenesis, a two-dimensional, semigeostrophic model with a now standard parameterization of latent heat release is used to diagnose the structure, energetics, and propagation characteristics of short-scale, diabatic normal modes in a moist, baroclinic atmosphere with the Eady basic state.
