RISSensitivity of Typhoon Track Predictions in a Regional Prediction System to Initial and Lateral Boundary Conditions
Publisher: American Meteorological Society
Abstract: Tropical cyclone (TC) track predictions from the operational regional nonhydrostatic TC forecast system of the Taiwanese Central Weather Bureau (CWB) are examined for their sensitivities to initial and lateral boundary ...
Improvement of Numerical Prediction of Typhoon Tracks in the Western North Pacific Basin near Taiwan
Publisher: American Meteorological Society
Abstract: In an effort to improve the tropical cyclone track forecast, two preprocessing procedures are applied to an operational baroclinic forecast system at the Central Weather Bureau (CWB) in Taipei. The first replaces the ...
A Vortex Relocation Scheme for Tropical Cyclone Initialization in Advanced Research WRF
Publisher: American Meteorological Society
Abstract: This paper introduces a relocation scheme for tropical cyclone (TC) initialization in the Advanced Research Weather Research and Forecasting (ARW-WRF) model and demonstrates its application to 70 forecasts of Typhoons ...
Application of WRF 3DVAR to Operational Typhoon Prediction in Taiwan: Impact of Outer Loop and Partial Cycling Approaches
Publisher: American Meteorological Society
Abstract: n this paper, the impact of outer loop and partial cycling with the Weather Research and Forecasting Model?s (WRF) three-dimensional variational data assimilation system (3DVAR) is evaluated by analyzing 78 forecasts for ...
Blending of Global and Regional Analyses with a Spatial Filter: Application to Typhoon Prediction over the Western North Pacific Ocean
Publisher: American Meteorological Society
Abstract: blending method to merge the NCEP global analysis with the regional analysis from the WRF variational data assimilation system is implemented using a spatial filter for the purpose of initializing the Typhoon WRF (TWRF) ...
