    Abstract: 在傳統的區域資料同化與預報系統中,多半僅使用單一區域大氣模式。而海氣耦合的 作用僅單單由海溫單向提供。因此在模擬(預報)颱風的過程中缺乏了海氣耦合的交互作 用,將會忽略了颱風-海洋回饋效應對颱風發展造成之影響。而此,也可使系集同化系 統中在洋面上的低層大氣的系集離散度不足而導致誤差被低估,進而影響系集同化系 統的表現。 透過颱風-海洋交互作用的概念,本計劃希望探討海氣耦合作用與颱風發展所在之低層 大氣誤差結構的關係,此外,海洋暖水層動力發展對海表面溫度不確定性(誤差)影響 等。並在區域系集資料同化及系集預;The regional weather assimilation and prediction system is usually performed with single regional atmospheric model. Even with SST updating the low boundary condition, the impact is one-way only. For tropical cyclone simulation/prediction, such two-way in;研究期間:10408~10507
