RISHow Do Outer Spiral Rainbands Affect Tropical Cyclone Structure and Intensity?
Publisher: American Meteorological Society
Abstract: A long-standing issue on how outer spiral rainbands affect the structure and intensity of tropical cyclones is studied through a series of numerical experiments using the cloud-resolving tropical cyclone model TCM4. Because ...
Vortex Rossby Waves in a Numerically Simulated Tropical Cyclone. Part II: The Role in Tropical Cyclone Structure and Intensity Changes
Publisher: American Meteorological Society
Abstract: In Part I, the author analyzed the asymmetric structure in the inner core of a numerically simulated tropical cyclone and found that the asymmetry near the eyewall in the mid?lower troposphere is dominated by wavenumber-1 ...
Vortex Rossby Waves in a Numerically Simulated Tropical Cyclone. Part I: Overall Structure, Potential Vorticity, and Kinetic Energy Budgets
Publisher: American Meteorological Society
Abstract: The asymmetric structure in the inner core of a numerically simulated tropical cyclone is analyzed in this study. The simulated tropical cyclone is found to be highly asymmetric in the inner core. In the mid?lower troposphere, ...
An Explicit Simulation of Tropical Cyclones with a Triply Nested Movable Mesh Primitive Equation Model: TCM3. Part I: Model Description and Control Experiment
Publisher: American Meteorological Society
Abstract: Results from an explicit simulation of tropical cyclones are presented in this study. The numerical model used in the study is the triply nested movable mesh primitive equation model newly developed by the author. It uses ...
An Inverse Balance Equation in Sigma Coordinates for Model Initialization
Publisher: American Meteorological Society
Abstract: In many numerical simulation studies there is a need to obtain the balanced initial fields in numerical models with σ as the vertical coordinate. By employing an equation that establishes the balance between the mass and ...
An Explicit Simulation of Tropical Cyclones with a Triply Nested Movable Mesh Primitive Equation Model: TCM3. Part II: Model Refinements and Sensitivity to Cloud Microphysics Parameterization
Publisher: American Meteorological Society
Abstract: It has been long known that cloud microphysics can have a significant impact on the simulations of precipitation; however, there have been few studies so far that have investigated the effect of cloud microphysics on ...
Structure and Formation of an Annular Hurricane Simulated in a Fully Compressible, Nonhydrostatic Model—TCM4
Publisher: American Meteorological Society
Abstract: The structure and formation of an annular hurricane simulated in a fully compressible, nonhydrostatic tropical cyclone model?TCM4?are analyzed. The model is initialized with an axisymmetric vortex on an f plane in a quiescent ...
Rapid Filamentation Zone in a Numerically Simulated Tropical Cyclone
Publisher: American Meteorological Society
Abstract: In a recent study, Rozoff et al. proposed a possible mechanism to explain the formation and maintenance of the weak-echo annulus (or moat) outside of the primary eyewall of a tropical cyclone observed in radar images. By ...
How Does Horizontal Diffusion Influence the Intensification and Maximum Intensity of Numerically Simulated Tropical Cyclones?
Publisher: American Meteorological Society
Weak Tropical Cyclones Dominate the Poleward Migration of the Annual Mean Location of Lifetime Maximum Intensity of Northwest Pacific Tropical Cyclones since 1980
Publisher: American Meteorological Society
Abstract: AbstractThe poleward migration of the annual mean location of tropical cyclone (TC) lifetime maximum intensity (LMI) has been identified in the major TC basins of the globe over the past 30 years, which is particularly ...
