    Abstract:
          The Kuroshio intrusion in a quasi-global eddy-resolving model (LICOMH) and a fully air-sea coupled model (LICOMHC) was evaluated against observations. We found that the Kuroshio intrusion was exaggerated in the former, while biases were significantly attenuated in the latter. Luzon Strait transport (LST) in winter was reduced from –8.8×106 m3/s in LICOMH to –6.0×106 m3/s in LICOMHC. Further analysis showed that different LST values could be explained by different large-scale and local surface wind stresses and the eddies east to the Luzon Strait as well. The relatively stronger cyclonic eddies in LICOMH northeast of the Luzon Island led to weak Kuroshio transport and strong intrusion through the Luzon Strait. The summed transport of all three factors was approximately 2.0×106 m3/s, which was comparable with the difference in LST between the two experiments. The EKE budget showed that strong EKE transport and the baroclinic transformation term led to strong cyclonic eddies east of the Kuroshio in LICOMH, while surface winds contributed little to the differences in the eddies.
    中文摘要:
          比較了準全球渦分辨率海洋模式(簡記為LICOMH)及其海氣耦合模式(簡記為LICOMHC)中的黑潮入侵南海與觀測中黑潮入侵的差異。我們發現在單獨海洋模式中黑潮入侵與觀測相比過強,而在其海氣耦合模式中這一差異得到了改善。冬季的呂宋海峽輸送(LST)在LICOMH中為-8.8×106 m3s-1,而在LICOMHC中則下降到-6.0×106 m3s-1 。進一步的研究表明是大尺度風場,局地風應力和呂宋海峽以東中尺度渦旋的共同作用導致了黑潮入侵在兩個模式中的不同。LICOMH中呂宋島東北部相對較強的氣旋導致了較弱的黑潮輸送及呂宋海峽處較強的黑潮入侵。以上三者共同作用造成的LST差異大約是2.0×106 m3s-1,與兩個模式間的LST差異大小基本相當。進一步對LICOMH與LICOMHC中的EKE收支進行分析表明,LICOMH中更強的EKE輸送及斜壓轉換項導致了黑潮以東存在更強的氣旋,而海表風場對兩個模式中的渦旋差異貢獻極小。
