摘　　要：海洋中尺度涡旋与其边缘的次中尺度锋面之间存在强烈的物质和能量交换以及复杂的动力过程。目前,对中尺度涡旋的调查研究已经日趋成熟,但由于次中尺度锋面的空间尺度小、时间变化快,对其三维结构的调查存在较大挑战。本文提出一种海洋中尺度涡旋边缘次中尺度锋面的调查方法。首先利用多源卫星遥感数据对中尺度涡旋及其边缘的次中尺度锋面进行识别,然后使用多型船载调查设备进行多学科综合调查。利用该方法对2023年8月21日至8月25日黑潮延伸体海域一个典型涡旋边缘次中尺度锋面进行调查方案设计。本文提出的调查方法可以有效地实现对中尺度涡旋边缘次中尺度锋面的识别、追踪与调查。There are strong exchange of matter and energy and complex dynamic processes between mesoscale ed-dies and submesoscale fronts at their edges.At present,the investigation of mesoscale eddies has become more and more mature,but because of the small spatial scale and rapid time change of the submesoscale front,it is a great challenge to investigate its three-dimensional structure.In this paper,a new method is proposed to investigate the submesoscale front at the edge of the ocean mesoscale eddy.Firstly,the submesoscale front at the edge of the meso-scale eddies is identified using multi-source satellite remote sensing data,and then the multi-type shipborne survey equipment is used for multidisciplinary investigation.A submesoscale front at the edge of typical eddies in the Kur-oshio Extension area from August 21 to August 25,2023 is investigated by using this method.The survey method proposed in this paper can effectively identify,track and investigate the submesoscale front at the edge of meso-scale eddies.
