| dc.description.abstract | 本文主要為利用一區域氣候系統模式針對美國加州蒙特瑞灣區域的海地氣交互作用進行模擬與調查。在本次模擬中特別針對現今各式之全球氣候模式中所欠缺的中小尺度擾動（聖克魯茲渦流、海陸風交互作等）進行探討。這些欠缺的中小尺度擾動對於大尺度模式在經由長時間累積的作用後可能會造成系統性的誤差。
本研究使用的為天氣研究與預測模式(WRF)與一陸地表面模式耦合之區域氣候模式，WRFCLM3，以及另一根基於非靜力近岸海洋之蒙特瑞灣區之模式(MBARM)所耦合成之海洋累積區域性氣候系統模式。 模式之結果分析指出，海洋累積區域性氣候系統模式之結果可以完整的將中小尺度擾動完整的呈現出來，同時也可以將海洋中的湧升及沉降流完整的模擬出來。在大尺度氣候場方面，本模式也可以將位於東北太平洋之東方邊界流與上方之大氣副熱帶高壓及其風場模擬完整。進一步利用本模式進行分析可以發現，在利於湧升流的風場條件下，海面會有1~1.5°C的降溫現象，與在同一時間時，觀測資料顯示出海面有2°C的降溫一致。與此同時的氣候值則只顯示出0.3°C的海洋降溫。藉此可以顯現出氣候值在此的缺陷。而海洋的海流也因為使用了WRFCLM3的風場做為初始場，使得海流之艾克曼湧升現象相較於使用氣候風場做為比較時增強，而與觀測值較為符合。在大氣的部份中，由於使用之海溫場較溫暖，因此大氣溫度場的部份亦較高，使得本身大氣的溼氣與含水量增加。 本研究指出，海洋累積區域性氣候系統模式為一重要之大氣與海洋耦合模式，同時也可增進未來氣候之研究。在計算允許的情況下，全球性之中小尺度氣候模式亦為一相當重要之研究目標。 | zh_TW |
| dc.description.abstract | Air-land-sea interaction in the vicinity of Monterey Bay, CA is simulated and investigated using a Regional Climate System Model (RCSM). Several coastal processes and submesoscale features can be fully resolved using the RCSM while these processes and features are poorly represented in the state-of-the-art global climate model, resulting in significant and systematic biases in the long term climate integration. The current RCSM couples the Weather Research and Forecast with Community Land Model version3 (WRFCLM3) and a full function coastal ocean model, which is based on the non-hydrostatic Monterey Bay Area Regional Model (MBARM). Our model results show the importance of detailed ocean feedback due to unique coastal dynamic. The comparison with observation indicates the requirement of accurate representation of ocean surface. In the ocean, the coastal upwelling and submesoscale gyres are well-simulated in the RCSM. The daily sea (land) breeze circulations and commonly-seen Santa Cruz Eddy (SCE) are fully resolved resulting from the sea surface temperature feedback and adequate resolution in the coastal margin. | en |
