摘　　要：潜热是大气能量的重要来源,海气界面潜热通量对于海气相互作用的研究具有重要意义。本文比较了1996—2005年J-OFURO2、HOAPS3、GSSTF3、OAFLUX、NCEP/NCAR再分析资料5种产品,研究结果表明5种月平均潜热通量产品基本一致,其中J-OFURO2、HOAPS3、GSSTF3较为接近,OAFLUX与NCEP/NCAR较为接近。比较不同的月平均潜热通量产品的统计特征,均方根误差最小的是GSSTF3与HOAPS3(14.08W/m^2),最大的是GSSTF3与NCEP/NCAR(25.98W/m^2),相关系数最小的是HOAPS3与NCEP/NCAR(0.87)、GSSTF3与OAFLUX(0.87)、最大的是GSSTF3与HOAPS3(0.97),5种潜热通量产品多年平均的纬向分布虽然基本相似但仍然存在差异,基于遥感数据的3种产品与OAFLUX、NCEP/NCAR再分析资料之间较大差值主要分布在太平洋和大西洋赤道区域、西北太平洋、印度洋北部。The interactions between the ocean and atmosphere play an important role in climate system.The ocean influences the atmosphere by transferring heat energy,while the atmosphere changes the ocean currents and redistribute ocean heat through wind stress.The latent heat（LHF）at the air-sea interface is an important source of the atmospheric energy.It is essential for the study of air-sea interaction.The five LHF monthly mean products including the Japanese Ocean Flux Datasets with Used Remote Sensing Observations version 2（J-OFURO2）,the Hamburg Ocean Atmosphere Parameters and Fluxes from Satellite Dataset version 3（HOAPS3）,the Goddard Satellite-Based Surface Turbulent Fluxes version 3（GSSTF3）,the Objectively Analyzed air-sea Fluxes（OAFLUX）and the National Centre for Environmental Prediction and the National Center for Atmospheric Research Reanalysis dataset（NCEP reanalysis）are compared in this paper.The statistics of the intercomparisons among these monthly LHF products over the global ocean during 1996—2005are analyzed.The results indicate that five LHF products have a similar patterns of global and zonal distribution,larger differences mainly locate in the trade winds zone and high latitude area.Three satellites-derived latent heat flux datasets,i.e.J-OFURO2,HOAPS3,GSSTF3 are close,with the root mean square error（RMSE）between each group of the two products less than 20W/m-2 and the correlations above 0.90.While OAFLUX is closer to NCEP with the RMSE less than 20W/m-2 and the correlations above 0.90.The lowest RMSE is between GSSTF3 and HOAPS3with the value of14.08W/m-2,the highest RMSE is between NCEP and GSSTF3（25.98W/m-2）.The lowest correlation is between NCEP and HOAPS3（0.87）as well as GSSTF3 and OAFLUX（0.87）,the highest correlation is between GSSTF3 and HOAPS3（0.97）.Zonal average values of five products reveal similar pattern with differences in specific zones.By analyzing the global differences among the five datasets,the differences among three satellite-derived la
