摘　　要：以西太平洋海域2个中尺度涡为例,利用AVISO卫星高度计观测的海平面高度异常(Sea Level Anomaly,SLA)数据、HYCOM模式的温度、盐度数据及水下滑翔机实测数据,分析了Ocean Data View软件(ODV)在实现该区域中尺度涡运动特征规律研究的实用性,探讨了中尺度涡分析处理的关键技术和方法。结果表明:利用ODV软件能够快速绘制海平面高度异常值和海表面流速的平面图,进而准确判别中尺度涡类型、追踪中尺度涡在海表面的水平空间尺度及演化特征;也可绘制任意航迹温、盐深断面图用于分析中尺度涡的垂直结构和判别涡结构类型;同时ODV软件也提供了垂直涡结构实测数据与模式数据对比分析模式,为中尺度涡研究提供强有力的分析工具和技术支撑方法。Based on the Sea Level Anomaly(SLA)data from the AVISO satellite altimeter,the temperature and salinity data from HYCOM mode and the actual measurement data of the underwater glider,2 mesoscale eddies in the western Pacific Ocean are used to analyze the practicality of the Ocean Data View(ODV)software in describing the motion characteristics of mesoscale eddies,and to discuss the key techniques and methods for data analysis and processing of mesoscale eddies.The results show that the ODV can be used to quickly map the sea level height anomalies and the sea surface currents plan,and then accurately determine the types of the mesoscale eddies and track their horizontal spatial scale and evolution process.The ODV can also map the temperature and salinity profiles of any track to analyze the vertical structure and determine the structure types of the mesoscale eddies.At the same time,the ODV also provides an analysis mode for the comparison between actual measured and modelled data of vertical eddy structures,which provides powerful analysis tools and technical support method to study the mesoscale eddies.
