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 ...
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 ...
On a Theory of Amplitude Vacillation in Baroclinic Waves: Some Numerical Solutions
Publisher: American Meteorological Society
Abstract: In an earlier paper (Smith, 1977) it is shown that when viscous effects are important only on a time scale much longer than that for incipient wave growth, the amplitude evolution of a marginally unstable baroclinic wave ...
The Effect of Vertical Stability on Tornadogenesis
Publisher: American Meteorological Society
Abstract: A recent numerical study of vortex growth in a flow configuration which models the principal characteristics of a tornado cyclone (Smith and Leslie, 1978) is extended to take account of vertical stability. It is shown that ...
The Morning Glory of the Gulf of Carpentaria: An Atmospheric Undular Bore
Publisher: American Meteorological Society
Abstract: This paper presents the results of a field expedition mounted in late September/early October 1979 to investigate the structure and origin of the ?morning glory? of the Gulf of Carpentaria in northern Australia. The morning ...
Cold Fronts Research: The Australian Summertime “Cool Change”
Publisher: American Meteorological Society
Abstract: Much of the significant weather of southeastern Australia is associated with the passage of cold fronts. In summer, such passages are often accompanied by rapid and extreme temperature fails, as hot continental northerly ...
