RISA Numerical Study of Outer Rainband Formation in a Sheared Tropical Cyclone
Publisher: American Meteorological Society
Abstract: AbstractThe dynamical process of outer rainband formation in a sheared tropical cyclone (TC) is examined in this study using the fully compressible, nonhydrostatic TC model. After the easterly vertical wind shear of 10 m ...
Impacts of Evaporation of Rainwater on Tropical Cyclone Structure and Intensity—A Revisit
Publisher: American Meteorological Society
Abstract: he impact of evaporation of rainwater on tropical cyclone (TC) intensity and structure is revisited in this study. Evaporative cooling can result in strong downdrafts and produce low?equivalent potential temperature air ...
Differences in Western North Pacific Tropical Cyclone Activity among Three El Niño Phases
Publisher: American Meteorological Society
Abstract: The impacts of El Niño on tropical cyclone (TC) activity over the western North Pacific (WNP) are examined through investigation of three types of tropical Pacific warming episodes according to where the maximum sea surface ...
Effects of Diabatic Heating and Cooling in the Rapid Filamentation Zone on Structure and Intensity of a Simulated Tropical Cyclone
Publisher: American Meteorological Society
Abstract: he effects of diabatic heating and cooling in the rapid filamentation zone (RFZ), within which inner rainbands are often active, on tropical cyclone (TC) structure and intensity are investigated based on idealized numerical ...
Diurnal Cycle of Rainfall Associated with Landfalling Tropical Cyclones in China from Rain Gauge Observations
Publisher: American Meteorological Society
Abstract: AbstractThe diurnal variation of rainfall over China associated with landfalling tropical cyclones (TCs) is investigated using hourly rain gauge observations obtained from 2425 conventional meteorological stations in China. ...
Tropical Cyclone Intensity Change from a Simple Ocean–Atmosphere Coupled Model
Publisher: American Meteorological Society
Abstract: The interaction between a tropical cyclone (TC) and the underlying ocean is investigated using an atmosphere?ocean coupled model. The atmospheric model is developed from the Pennsylvania State University (Penn State)?National ...
A High-Resolution Simulation of Typhoon Rananim (2004) with MM5. Part I: Model Verification, Inner-Core Shear, and Asymmetric Convection
Publisher: American Meteorological Society
Abstract: In this study, the fifth-generation Pennsylvania State University?National Center for Atmospheric Research (PSU?NCAR) Mesoscale Model (MM5) is used to simulate Typhoon Rananim (2004) at high resolution (2-km grid size). ...
Numerical Study on the Formation of Typhoon Ketsana (2003). Part I: Roles of the Mesoscale Convective Systems
Publisher: American Meteorological Society
Abstract: he effects of multiple mesoscale convective systems (MCSs) on the formation of Typhoon Ketsana (2003) are analyzed in this study. Numerical simulations using the Weather Research and Forecasting (WRF) model with assimilation ...
Impact of Four-Dimensional Variational Data Assimilation of Atmospheric Motion Vectors on Tropical Cyclone Track Forecasts
Publisher: American Meteorological Society
Abstract: The fifth-generation Pennsylvania State University?National Center for Atmospheric Research nonhydrostatic Mesoscale Model is employed to evaluate the impact of the Geostationary Meteorological Satellite-5 water vapor and ...
Evolution of the Warm-Core Structure during the Eyewall Replacement Cycle in a Numerically Simulated Tropical Cyclone
Publisher: American Meteorological Society
Abstract: AbstractThis study examines the evolution of the warm-core structure during the secondary eyewall formation (SEF) and the subsequent eyewall replacement cycle (ERC) in a numerically simulated tropical cyclone (TC) under ...
