| 摘要: |
| 文章基于卫星高度计资料和Argo浮标资料，采用合成方法，构建了黑潮延伸体邻近海区中尺度涡的温盐三维结构。合成结果表明，表层至1×107 Pa，合成气旋涡（反气旋涡）呈现较为一致的位温负（正）异常，气旋（反气旋）涡内呈现较为一致的位温负（正）异常，混合层至约7×106 Pa深度，气旋（反气旋）涡存在位温负（正）异常的冷核（暖）核结构。气旋（反气旋）涡的平均盐度在垂向上呈现“负—正”（“正—负”）上下相反的异常结构。 |

| Abstract: |
| Three dimensional structures of temperature,salinity,velocity of mesoscale eddies near the Kuroshio Extension Region were constructed by a composing method based on satellite altimetry data and Argo profile data.The results of the structures showed that,from surface to 1000 dbar depth,composed cyclonic (anticyclonic) eddy represent consistent temperature negative (positive) anomaly,from the mixed layer to about 700 dbar depth,there exists a cold (warm) core with negative (positive) temperature anomaly.The structure of the salinity of cyclonic eddy presented as “negative-positive” salinity anomaly structure in upper and lower layer,while it is opposite for anticyclonic eddy. |
