中文摘要：

基于2005 年1 月~2009 年12 月中国Argo 实时数据中心发布的Argo 网格化产品, 对台湾以东海域的表层和深层海温进行了分析, 证实了日本南部海域存在北太平洋副热带模态水, 提出暖水团概念, 分析了其成因和垂直结构, 并利用SODA（Simple Ocean Data Assimilation）数据和WOA09（World Ocean Atlas 2005）数据对暖水团进行验证.揭示出台湾以东海域各层次温度大面分布大体呈3 个模态特征, 并依此将台湾以东海域分为热带、副热带和温带三个海区; 对各海域截取断面图, 对其温跃层进行分析, 归纳出永久性温跃层和季节性温跃层在垂直方向上的分布和季节性变化, 并对其成因进行了讨论.

英文摘要：

Based on gridded Argo data during 2005~2009 provided by the Real-time Argo Data Center in China, the surface and deepocean temperature of the ocean east of Taiwan are investigated. The results show that the North Pacific Subtropical Mode Waterexists south of Japan. The authors put forward an idea of constant warm mode water, revealed its cause and vertical structure, andconfirm it with SODA （Simple Ocean Data Assimilation） and WOA09 （World Ocean Atlas 2005） data. It can be concluded that thereare three kinds of mode in different layers of the ocean east of Taiwan. Thus, the ocean east of Taiwan can be divided into three areas：tropical area, subtropical area and temperate area. By analyzing the thermocline of each area using thermocline profiles, permanentand seasonal thermoclines’ vertical distributions and seasonal variability are summarized. They authors provided explanations tothese results.
