摘　　要：采用WOA13气候态季节温度数据,利用绝对梯度法对东海黑潮不同水深海洋锋的季节变化特征进行了分析,得出结论:东海黑潮温度锋具有显著的季节变化特征,它的范围和强度存在多个大值区,不同季节,温度锋的大值区存在于不同深度。在200 m以浅海域,按照冬季、春季、夏季的季节顺序,温度锋的大值区由表层逐渐增加到100 m层处;在200 m以深海域温度锋的大值区没有季节变化,大值区大约出现在400 m层附近。By analyzing WOA13 season average data,the seasonal variation of the Kuroshio temperature front in the East China Sea under different depth was studied by using absolute gradient method.It showed that the Kuroshio temperature front had significant seasonal variation,there were several high value area of range and intensity in different depth,and there were changes with season.In the depth less than 200 m,the high value area moved from surface to 100 m depth follow the order of winter,spring and summer.In the depth deeper than 200 m,the high value area existed in 400 m depth layer,but the seasonal variation cannot be found.
