摘要:
应用Argos表层漂流浮标资料所指示的浮标轨迹图以及基于卫星高度计资料和三维水动力模型海面高度场数据的经验正交函数(EOF)模态分析,探讨了黑潮在吕宋海峡形变的时空分布特征.结果表明:吕宋海峡黑潮的形态呈现明显的季节变化,其中跨隙形态为其最基本的形态;秋冬两季,部分黑潮水会以流套和分支的形式入侵南海,流套最西可延伸至118°E;春夏季节则几乎不出现流套或者分支的结构,相反会有一部分南海水汇入黑潮主干.模型数据模态分析结果还再现了冬季黑潮水沿着南海北部陆坡向西入侵的形态.
Abstract:
The temporal and spatial variations of Kuroshio patterns in the Luzon Strait were studied with the use of the Argos surface drifter data,as well as empirical orthogonal function (EOF) mode analysis of the satellite altimeter data and the sea surface height data resulting from a threedimensional hydrodynamic model.Both trajectories of Argos surface drifting buoys and EOF mode analysis results reveal that the Kuroshio patterns in the Luzon Strait have significant seasonal variations.Kuroshio leaps across the Luzon Strait all around the year.During fall and winter,Kuroshio also loops and branches into the South China Sea (SCS) through the Luzon Strait,the loop can intrude as far as 118°E,but it seldom happens in the other two seasons when SCS water joins into the Kuroshio in reverse.Model data EOF mode analysis results also indicate that one branch of Kuroshio intrudes into SCS along the continental slope of northern SCS in winter.
