    Abstract: 前期計畫已經協助CWB/GFS 在GSI-Hybrid 的系統架構下,完成了混合式(Hybrid)資料同化方法相關測試,並擴充additive inflation 的機制,藉由增加NMC-method (National Meteorological Center) 添加系集擾動,使得Hybrid 資料同化系統更加完善。前期測試包括優化混合法資料同化相關參數之測試與分析:針對混合法中有關取用靜態與系集背景誤差之權重參數;及進一步評估混合法資料同化使用不同系集成員數目的預報結果:以不同系集成員數目進行一個月;In the previous project, hybrid data assimilation method has been tested under CWB/GFS GSI-Hybrid framework with the additive inflation to enhance ensemble perturbations thru NMC-method, including analysis of optimal hybrid parameters for static and ensem;研究期間:10401~10412
