RISEnsemble Typhoon Quantitative Precipitation Forecasts Model in Taiwan
Publisher: American Meteorological Society
Abstract: n this study, an ensemble typhoon quantitative precipitation forecast (ETQPF) model was developed to provide typhoon rainfall forecasts for Taiwan. The ETQPF rainfall forecast is obtained by averaging the pick-out cases, ...
Comparing Limited-Area 3DVAR and Hybrid Variational-Ensemble Data Assimilation Methods for Typhoon Track Forecasts: Sensitivity to Outer Loops and Vortex Relocation
Publisher: American Meteorological Society
Abstract: he Weather Research and Forecasting Model (WRF) ?hybrid? variational-ensemble data assimilation (DA) algorithm was used to initialize WRF model forecasts of three tropical cyclones (TCs). The hybrid-initialized forecasts ...

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) ...
