利用涡旋分辨海洋环流模式，研究了从黑潮延伸区(KE)剥离出来的冷核环，重点研究了它们的示踪输送。通过释放两种被动示踪剂，分别对应于KE水和KE以北混合水区(MWR)的水，直接调查了环中示踪剂的来源和它们是如何被捕获的。在夹点时，冷芯环携带着由KE水包裹的MWR中的示踪剂从表面到底部。在上层温跃层之内和之上(西格玛
Using an eddy-resolving ocean general circulation model, we examine the cold-core rings pinched off from the Kuroshio Extension (KE), focusing on their tracer transport. The origin of the tracers in the rings and how they are trapped are directly investigated by releasing two passive tracers, corresponding to the KE water and the water in the Mixed-Water Region (MWR) to the north of the KE. The cold-core rings carry the tracer in the MWR wrapped by the KE water from the surface to the bottom at the pinch-off. In and above the upper thermocline (sigma
