Abstract: A highly simplified model for the wave?mean flow interaction in a baroclinic wave life cycle is derived from the quasigeostrophic two-layer system. The simplification is based on a sheared disturbance embedded in a zonal ...

Abstract: This study examines the cyclone?anticyclone asymmetry within idealized baroclinic waves. For this purpose a primitive equation (PE) model and a quasigeostrophic (QG) model are used. The Rossby number appears to be an ...

Abstract: his paper addresses the validity of the gradient wind balance approximation during the intensification phase of a tropical cyclone in Ooyama?s three-layer model. For this purpose, the sensitivity to various model modifications ...

Abstract: manuel?s theory of hurricane potential intensity (E-PI) makes use of the assumption that slantwise convective instability vanishes in a steady-state vortex of a tropical cyclone. In the framework of an extended mathematical ...

Abstract: hreefold densities may be introduced into atmospheric thermodynamics. For rainless clouds the general indirect or implicit conclusion is that they are denser than moist air under the same circumstances, although in a classic ...

Abstract: The local mass balance equations of cloudy air are formulated for a model system composed of dry air, water vapor, and four categories of water condensate particles, as typically adopted for numerical weather prediction ...

Abstract: he assumption of gradient wind balance is customarily made so as to derive the theoretical upper-bound intensity of a mature tropical cyclone. Emanuel's theory of hurricane potential intensity (E-PI) makes use of this ...
