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.

针对观测结果评估了准全球涡旋解析模型（LICOMH）和完全海海耦合模型（LICOMHC）中的黑潮入侵。我们发现，在前者中，黑潮的入侵行为被夸大了，而在后者中，偏见被大大减弱了。冬季的吕宋海峡运输（LST）从LICOMH中的-8.8×10 ⁶ m ³ / s降低至-6.0×10 ⁶ m ³/ s在LICOMHC中。进一步的分析表明，不同的LST值可以用不同的大规模和局部表面风应力以及吕宋海峡以东的涡旋来解释。吕宋岛东北部LICOMH中相对较强的气旋涡导致了黑潮交通不畅和强烈入侵吕宋海峡。所有这三个因素的总输运约为2.0×10 ⁶ m ³ / s，这与两个实验之间的LST差异相当。EKE预算显示，强劲的EKE运移和斜压转换期导致了LICOMH黑潮以东的强烈旋风涡，而表面风对涡旋差异的贡献很小。
