(1989)等，以瞭解積雲及大尺度降水參數化法之理論架構。<br> Abstract: This project will perform the quasi-operational simulation tests (including data assimilation) with the new Tiedtke cumulus scheme to simulate the different time scale systems (typhoon, Mei-yu front, etc.) and access the forecast skill (correlation coefficient, root mean square error, etc.) to evaluate the capability of the new Tiedtke scheme in CWB/GFS. In addition, we will review the previous studies (Chappell 1980; Zhao and Carr 1997; Sundqvist et al. 1989) to understand the theoretical framework of cumulus and large-scale precipitation parameterizations.new Tiedtke scheme降水參數化法相關係數方均根誤差new Tiedtke schemeprecipitation parameterizationcorrelation coefficientroot mean square error
