| 摘 要： | 基于西北太平洋Argo数据资料,利用参数化方法,从Argo温盐剖面数据中提取出一系列特征动力参数,定量分析黑潮延伸体海域水体的三维热结构的时-空变化特征、季节变化特征及其与地形和环流的关系。结果表明:黑潮延伸体海域水体的海表面温度存在着明显的冬春弱,夏秋强的季节变化特征,冬季平均海表面温度为15℃,夏季则达到了27℃;混合层深度在春季和夏季都较深,在180 m左右,秋冬较浅,在17 m左右,在水平方向上混合层深度有较强的梯度;温跃层春、夏、秋、冬4季的平均温度表现出明显的南北差异,夏季南部海域平均温度为14℃左右,北部海域较低为5℃左右;季节性温跃层深度大约在100 m左右;黑潮延伸体海域水体的温跃层底部最大深度在800 m左右;黑潮延伸体主体海域中心位置冬天在36°N左右,夏天大约移到34°N。

| Abstract: | Based on the Argo data in the Northwestern Pacific,a series of characteristic dynamic parameters were extracted from the Argo temperature-salt profile data using parameterized methods,and used for quantitative analysis of the Kuroshio extension sea water body three dimensional thermal structure of the space-time variation characteristics.This paper studied the area of three dimensional thermal structure of seasonal variation characteristics and its relationship with topography and the circulation.The results showed that the sea surface temperature of the Kuroshio extension body was characterized by seasonal variations of winter,spring,summer and autumn.The average sea surface temperature was 15℃in winter and 27℃in summer.The depth of the mixing layer is deep in spring and summer,about 180 m;in autumn and winter,it is shallow,about 17 m;in the horizontal direction,there is a strong gradient in the depth of the mixing layer.The average temperature scale of the thermocline in spring,summer,autumn and winter shows a significant difference between the north and the south.In summer,the average temperature of the southern sea area is about 14℃,while that of the northern sea area is relatively low at about 5℃.The depth of seasonal thermocline is about 100 m,and the maximum depth of the thermocline bottom is about 800 m in the Kuroshio extension area.The central location of the main body of the Kuroshio extension body is about 36°N in winter and about 34°N in summer. |
