Decoupling of Balanced and Unbalanced Motions and Inertia–Gravity Wave Emission: Small versus Large Rossby Numbers
Publisher: American Meteorological Society
Abstract: This paper provides a brief review of recent results on decoupling of fast [inertia?gravity wave (IGW)] and slow (vortex) motions at small Rossby numbers obtained in the framework of the geostrophic adjustment of localized ...
Understanding Instabilities of Tropical Cyclones and Their Evolution with a Moist Convective Rotating Shallow-Water Model
Publisher: American Meteorological Society
Abstract: nstabilities of hurricane-like vortices are studied with the help of a rotating shallow-water model, including the effects of moist convection. Linear stability analysis demonstrates that dominant unstable modes are mixed ...
Moist versus Dry Baroclinic Instability in a Simplified Two-Layer Atmospheric Model with Condensation and Latent Heat Release
Publisher: American Meteorological Society
Abstract: he authors undertake a detailed analysis of the influence of water vapor condensation and latent heat release upon the evolution of the baroclinic instability. The framework consists in a two-layer rotating shallow-water ...
Moist versus Dry Barotropic Instability in a Shallow-Water Model of the Atmosphere with Moist Convection
Publisher: American Meteorological Society
Abstract: ynamical influence of moist convection upon development of the barotropic instability is studied in the rotating shallow-water model. First, an exhaustive linear ?dry? stability analysis of the Bickley jet is performed, ...
