摘　　要：针对实际海洋中三维海流观测困难和流场资料欠缺的问题,通过ARGO浮标观测资料与WOA09背景场资料进行最优插值融合,得到较精细的温盐网格化资料,并在此基础之上通过引入P矢量方法,对太平洋海区的三维流场进行了诊断推算。分析表明:ARGO浮标再分析融合数据能够较好表现太平洋温盐场分布结构,在此基础之上诊断推算的三维流场能够合理刻画太平洋流场的基本特征,为获取大尺度海洋三维流场信息提供了有效的途径。Aiming at such difficulties as lack of three-dimensional sea currents observational data in the actual marine science research, based on serried three-dimensional temperature and salinity gridding information syncretized by ARGO bu0yage data （be normalized by optimal interpolation technique） and WOA09 data set, the P vector idea and technique was introduced to calculate the three-dimensional sea currents field in the Pacific. The experimental results show that Gridded temperature and salinity fields provided by ARGO data can describe the distributing structure of the actual ocean; and the calculated sea currents can depict the characteristic features at different depths layers of the Pacific ocean, a effective technique way was offered for obtaining large scale 3-dimensional sea flow field.
