Tropical Cyclone Eye Dynamics
Publisher: American Meteorological Society
Abstract: A new perspective of the dynamics of a tropical cyclone eye is given in which eye subsidence and the adiabatic warming accompanying it are accounted for directly from the equations of motion. Subsidence is driven by an ...
On the Effects of Vorticity Entrainment in Zonal Jet Flows
Publisher: American Meteorological Society
Abstract: There is a tendency for certain flows in the atmosphere and oceans to concentrate into narrow streams or currents, which preserve their identity over very large distances. The ability of such flows to overcome the diffusive ...
On Limit Cycles and Vacillating Baroclinic Waves
Publisher: American Meteorological Society
Abstract: This paper contains a study of the energy conversions in Pedlosky's solution for finite-amplitude baroclinic wave development for the case of small dissipation. It is shown that the solution contains an implicit, non-physical ...
The Steepening of Hydrostatic Mountain Waves
Publisher: American Meteorological Society
Abstract: The nonlinear effects in the flow of a Boussinesq stratified fluid over two-dimensional sinusoidal topography are examined in this paper using second-order perturbation theory. The waves generated by finite-amplitude ...
Transient Dynamics of Airflow near a Local Heat Source
Publisher: American Meteorological Society
Abstract: The response of a stratified atmosphere to local heating is a common element in several problems in mesoscale dynamics. To investigate this response, a time-dependent linearized problem is solved analytically for an elevated, ...
On Resonant Interactions Between Unstable and Neutral Baroclinic Waves
Publisher: American Meteorological Society
Abstract: Resonant interactions between a marginally unstable baroclinic wave and one or two pairs of neutral waves in a rotating, two-layer zonal Row model are studied. Analyses based on a multiple scaling technique are carried out ...
Water Vapor Transport and the Production of Precipitation in the Eastern Fertile Crescent
Publisher: American Meteorological Society
Abstract: The study presented here attempts to quantify the significance of southerly water vapor fluxes on precipitation occurring in the eastern Fertile Crescent region. The water vapor fluxes were investigated at high temporal ...
