摘　　要：中尺度涡对大洋环流、海洋能量平衡、水团分布、热盐和营养物质输运等方面都具有重要意义。根据其垂向密度结构和旋转流速核心位置不同,中尺度涡有表层和次表层中尺度涡之分。基于卫星海面高度计资料的应用,对表层中尺度涡的研究日趋成熟。次表层中尺度涡垂向密度呈透镜式结构,其最大旋转流速核心位于混合层以下,对次表层涡的研究依赖于现场观测资料。目前次表层涡在世界大洋中偶有发现,因此国内外对其研究方兴未艾。聚焦于西北太平洋的次表层中尺度涡,全面回顾了其观测和数值模式的结果,总结了其垂向结构特征、时空分布和移动规律,以及可能的生成机制等。同时展望了其对海洋能量平衡、水团分布、声传播和海洋生物地球化学要素分布等可能的影响,以及未来可能的研究发展方向。Mesoscale eddies play an important role in phenomena such as general circulation,momentum budgets,ocean water mass distribution,and water and nutrient transport.Based on the vertical structure of the density and current core,mesoscale eddies are classified into two categories:surface-and subsurface-intensified.The utilization of remote sensing has provided considerable information on surface-intensified eddies.However,little is known about subsurface eddies due to the lack of in-situ observations,although they have been found occasionally in the global ocean.Currently,subsurface eddies are a trending topic within the scientific community.This study reviews the scientific background and research progress on subsurface eddies,with a focus on the northwestern Pacific Ocean.The vertical structure,evolutionary process,and possible formation mechanism of subsurface eddies are summarized based on observational and modelling results.Their influence on marine biogeochemistry,marine sound propagation,and possible important scientific issues are also discussed.
