摘　　要：海洋中尺度涡作为物质循环、能量串级和信息传递的关键尺度和重要环节,具有丰富的热动力学内涵。文章基于中国近海及毗邻海域的涡动能分区,重点综述中尺度涡的运动属性、动力学本质和局地特征,从尺度局限与尺度关联的角度阐示中尺度涡旋的扰动生成、传播、能量级联和耗散,及其在海洋多尺度动力过程、热盐配置、生源要素调控和中尺度海气相互作用中的影响,并就相关科学问题和进展提出研究建议。研究结果表明:研究中尺度涡的演变规律对理解海洋物质能量传递的多维度层次、尺度规模和过程形式具有重要意义,需整体加深海洋中尺度涡自适应观测和可预报性研究,增强海洋中尺度涡的尺度演绎分析和特异性分析,建立从天气尺度到气候环境变化、生物生态影响以及致害致灾风险的能量信息通道,构建中观海洋生态系统动力学理论与模型,探索海洋中尺度涡精细化灾害风险预评估区划和安全保障新途径。As the key scale and important link of material cycle,energy cascade and information transmission,ocean mesoscale eddy(OME)has rich thermodynamic connotation.Based on the kinetic energy zoning of OME in China seas and the adjacencies(CSA),this paper mainly summarized the motion properties,dynamic essence and local characteristics of the OME in the CSA,and elaborated generation,propagation and energy cascade dissipation of OME disturbances,as well as the impaction of the OME in the processes of ocean current dynamics,heat and salt allocation,biogenic elements cycle and mesoscale sea-air interaction from the perspective of scale limitation and association,and subsequently put forward research suggestions on relevant scientific issues and progress.The results showed that the evolution and dynamics of the OME was of great significance for understanding the multi-dimensional levels,scale-quantity and process-forms of the material and energy transmission in the ocean.It was necessary to comprehensively deepen the research on the self-adaptive observation and the predictability of OME,enhance the studies on scale deduction and specificity,establish an energy information channel from the weather scale to the climatic,environmental,ecological impaction and disaster risk,and build the theory and model of mesoscopic ecosystem dynamics.We should explore new ways,from the viewpoint of the OME,to refine disaster risk projection,zoning and security governance.
