Behavior of Kuroshio warm-core rings and their role in material transport

对各种存档数据和现场观测进行了分析，以澄清黑潮暖核环的行为及其在物质运输中的作用。利用卫星海面高度场资料，对黑潮-大洋洲延伸区各种中尺度涡旋的分布和特征进行了量化。对环中心附近垂直廓线的研究表明，环暖水以下的中间层存在冷淡水异常。

Analyses on various archived data and in situ observations were conducted to clarify behavior of Kuroshio warm-core rings and their role in material transport. Based on satellite sea surface height data, we quantified the distribution and characteristics of various mesoscale eddies in the Kuroshio-Oyashio extension region. Invistigation on vertical profiles near the center of the rings revealed the occurrence of cold and fresh water anomalies in the intermediate layer below the warm water of the rings.
