RISNote on Analyzing Perturbation Growth in a Tropical Cyclone–Like Vortex Radiating Inertia–Gravity Waves
Publisher: American Meteorological Society
Abstract: method is outlined for quantitatively assessing the impact of inertia?gravity wave radiation on the multimechanistic instability modes of a columnar stratified vortex that resembles an intense tropical cyclone. The method ...
On the Role of Asymmetric Convective Bursts to the Problem of Hurricane Intensification: Radiation of Vortex Rossby Waves and Wave–Mean Flow Interactions
Publisher: American Meteorological Society
Abstract: he role of asymmetric convection to the intensity change of a weak vortex is investigated with the aid of a ?dry? thermally forced model. Numerical experiments are conducted, starting with a weak vortex forced by a localized ...
Spontaneous Emission of Spiral Inertia–Gravity Waves and Formation of Elliptical Eyewalls in Tropical Cyclone–Like Vortices: Three-Dimensional Nonlinear Simulations
Publisher: American Meteorological Society
Abstract: AbstractAlthough intense tropical cyclones (TCs) are considered to be axisymmetric vortices, observations reveal that they are often highly asymmetric. Better understanding of the underlying asymmetric dynamics is a critical ...
On the Origin and Impact of a Polygonal Eyewall in the Rapid Intensification of Hurricane Wilma (2005)
Publisher: American Meteorological Society
Abstract: n analysis of a high-resolution dataset from a realistic simulation of Hurricane Wilma (2005) was performed to understand the mechanism for the formation of a prominent polygonal eyewall and mesovortices during the rapid ...
Impact of Asymmetric Dynamical Processes on the Structure and Intensity Change of Two-Dimensional Hurricane-Like Annular Vortices
Publisher: American Meteorological Society
Abstract: n this study, a simple two-dimensional (2D) unforced barotropic model is used to study the asymmetric dynamics of the hurricane inner-core region and to assess their impact on the structure and intensity change. Two sets ...
Sensitivity of Tropical Cyclone Intensification to Axisymmetric Heat Sources: The Role of Inertial Stability
Publisher: American Meteorological Society
Abstract: his study examines the influences of an axisymmetric heat source on the tangential wind structure of a tropical cyclone (TC). Specifically, the response of a TC due to the effect of convection located in varying inertial ...
On the Relative Contribution of Inertia–Gravity Wave Radiation to Asymmetric Instabilities in Tropical Cyclone–like Vortices
Publisher: American Meteorological Society
Abstract: ntense atmospheric vortices such as tropical cyclones experience various asymmetric instabilities during their life cycles. This study investigates how vortex properties and ambient conditions determine the relative ...

Barotropic Instability across the Moat and Inner Eyewall Dissipation: A Numerical Study of Hurricane Wilma (2005)
Publisher: American Meteorological Society
Abstract: AbstractRadar imagery of some double-eyewall tropical cyclones shows that the inner eyewalls become elliptical prior to their dissipation. These elliptical features indicate that the barotropic instability (BI) across the ...
A Possible Three-Dimensional Mechanism for Oscillating Wobbles in Tropical Cyclone–Like Vortices with Concentric Eyewalls
Publisher: American Meteorological Society
Abstract: AbstractIt is known that concentric eyewalls can influence tropical cyclone (TC) intensity. However, they can also influence TC track. Observations indicate that TCs with concentric eyewalls are often accompanied by wobbling ...
