RISLarge-Scale Environmental Parameters Associated with Tropical Cyclone Formations in the Western North Pacific
Publisher: American Meteorological Society
Abstract: The local environmental conditions associated with 405 tropical cyclone (TC) formations in the western North Pacific during 1990?2001 are examined in this study. Six large-scale parameters are obtained and computed from ...
Tropical Cyclone Formations over the Western North Pacific in the Navy Operational Global Atmospheric Prediction System Forecasts
Publisher: American Meteorological Society
Abstract: A set of criteria is developed to identify tropical cyclone (TC) formations in the Navy Operational Global Atmospheric Prediction System (NOGAPS) analyses and forecast fields. Then the NOGAPS forecasts of TC formations ...
Ensemble Forecasting of Tropical Cyclone Motion Using a Barotropic Model. Part II: Perturbations of the Vortex
Publisher: American Meteorological Society
Abstract: In Part I of this study, the technique of ensemble forecasting is applied to the problem of tropical cyclone motion prediction by perturbing the environmental flow. In this part, the focus is shifted to perturbation of the ...
Tropical Cyclone Formations in the South China Sea Associated with the Mei-Yu Front
Publisher: American Meteorological Society
Abstract: This study examines the 119 tropical cyclone (TC) formations in the South China Sea (SCS) during 1972?2002, and in particular the 20 in May and June. Eleven of these storms are associated with the weak baroclinic environment ...
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 ...
The Role of Trade Wind Surges in Tropical Cyclone Formations in the Western North Pacific
Publisher: American Meteorological Society
Abstract: A total of 40 out of 531 tropical cyclones that formed in the western North Pacific during 1986?2005 have accompanied trade wind surges located 5°?15° latitude to the north of the pretropical cyclone disturbance centers. ...
Numerical Study of the Rainfall Event due to the Interaction of Typhoon Babs (1998) and the Northeasterly Monsoon
Publisher: American Meteorological Society
Abstract: A heavy rainfall event in the Taiwan area associated with the interaction between Typhoon Babs (1998) and the East Asia winter monsoon is studied. Typhoon Babs is a case in point demonstrating the often-observed phenomenon ...
Ensemble Forecasting of Tropical Cyclone Motion Using a Barotropic Model. Part I: Perturbations of the Environment
Publisher: American Meteorological Society
Abstract: The technique of ensemble forecasting is applied to the problem of tropical cyclone motion prediction. Three methods of generating perturbations for the environmental flow, Monte Carlo forecast (MCF), lagged-average forecast ...
The Impact of Tropical Storm Paul (1999) on the Motion and Rainfall Associated with Tropical Storm Rachel (1999) near Taiwan
Publisher: American Meteorological Society
Abstract: A heavy rainfall event associated with the passage of Tropical Storm Rachel (1999) over southern Taiwan was studied in which a conceptual model was proposed. In the model, Tropical Storm Paul (1999) plays an important role ...
Mesoscale Features Associated with Tropical Cyclone Formations in the Western North Pacific
Publisher: American Meteorological Society
Abstract: The mesoscale features of 124 tropical cyclone formations in the western North Pacific Ocean during 1999?2004 are investigated through large-scale analyses, satellite infrared brightness temperature (TB), and Quick ...
