The Maximum Potential Intensity of Tropical Cyclones
Publisher: American Meteorological Society
Abstract: A thermodynamic approach to estimating maximum potential intensity (MPI) of tropical cyclones is described and compared with observations and previous studies. The approach requires an atmospheric temperature sounding, ...
Tropical Cyclone Motion. A Comparison of Theory and Observation
Publisher: American Meteorological Society
Abstract: The analytic predictions of tropical cyclone motion by Holland are shown to be in very good agreement with observations in the Australian southwest Pacific region. These results indicate that a combined linear asymmetric ...
Tropical Cyclone Motion: Environmental Interaction Plus a Beta Effect
Publisher: American Meteorological Society
Abstract: The dynamics of tropical cyclone motion are investigated by solving for instantaneous motion tendencies using the divergent barotropic vorticity equation on a beta plane. Two methods of solution are presented a direct ...
An Analytic Model of the Wind and Pressure Profiles in Hurricanes
Publisher: American Meteorological Society
Abstract: An analytic model of the radial profiles of sea level pressure and winds in a hurricane is presented. The equations contain two parameters which may be empirically estimated from observations in a hurricane or determined ...
Interannual Variability of the Australian Summer Monsoon at Darwin: 1952–82
Publisher: American Meteorological Society
Abstract: Fluctuations in the Australian summer monsoon over the period 1952?82 are described. The basis of the study is an objective definition of the major summer monsoon components based on the low-level zonal winds at Darwin; ...
The Meandering Nature of Tropical Cyclone Tracks
Publisher: American Meteorological Society
Abstract: The observed tendency for tropical cyclones to meander about a longer-term track with periods of several days and amplitudes around 100 km is investigated. An analysis of 26 cyclones in the western North Pacific Ocean does ...
Baroclinic Dynamics of Simulated Tropical Cyclone Recurvature
Publisher: American Meteorological Society
Abstract: The mechanisms associated with tropical cyclone recurvature are investigated using a five-level primitive equation model and an idealized environment with characteristics observed in cyclone recurvature conditions. All ...
The Beta Drift of Baroclinic Vortices. Part I: Adiabatic Vortices
Publisher: American Meteorological Society
Abstract: The dynamics of the movement of an initially axisymmetric baroclinic vortex embedded in an environment at rest on a beta plane is investigated with a three-dimensional primitive equation model. The study focuses on the ...
Tropical Cyclone Motion and Evolution in Vertical Shear
Publisher: American Meteorological Society
Abstract: The motion and the evolution of tropical cyclone-like vortices in an environmental flow with vertical shear are investigated using a baroclinic primitive equation model. The study focuses on the fundamental dynamics of a ...
The Beta Drift of Baroclinic Vortices. Part II: Diabatic Vortices
Publisher: American Meteorological Society
Abstract: The beta drift of diabatic vortices is investigated with a three-dimensional primitive equation model with simple physical parameterizations. The vertical coupling mechanism discussed in Part I is extended to include the ...
