The goal of this project is to evaluate and implement the FV3 model with Taiwan’s unique features in CWB environment. For the first year, the FV3 model will be studied and constructed in CWB. A suitable pre-process and post process will also be implement to simulate some historical weather events. In the second year, this project will evaluate the forecast performance systematically. The computing performance and scaling test will also be tested in CWB’s high-performance computing environments. A suitable data assimilation system in the base of CWB GSI data assimilation system will be studied in the third year for the purpose of establish the operational process. Through the three years study and validate of FV3 model, we hope to enhance Taiwan’s own ability in researching and improving the numerical weather prediction for the next generation CWB GFS.中央氣象局全球模式預報系統FV3全球模式數值天氣預報CWB Global Forecast SystemFV3 global modelnumerical weather prediction
