【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。
[Abstract]:Latent heat is an important source of atmospheric energy. In this paper, we compare 5 kinds of reanalysis data of J-OFUROO2HOAPS3 / GSSTF3OAFLUX / NCEP / NCAR from 1996 to 2005. The results show that the five monthly mean latent heat flux products are basically the same, of which J-OFUROOURO2HOAPS3 GSSTF3 is close to OAFLUX and NCEP / NCAR. Comparing the statistical characteristics of products with different monthly mean latent heat flux, The root mean square error (RMS) of GSSTF3 and HOAPS3 is 14.08 W / m-2, and the largest is GSSTF3 and NCEP / NCARN 25.98 W / m-2, and the least correlation coefficient is HOAPS3 and NCEP / NCARN 0.87, GSSTF3 and OAFLUX 0.87, and the largest is GSSTF3 and HOAPS30.970.97. although the annual average latitudinal distribution of GSSTF3 and HOAPS30.97 is still similar, there are still differences in the annual average latitudinal distribution of GSSTF3 and NCEP / NCARN 0.87. The difference between the three products based on remote sensing data and OAFLUXN NCEP / NCAR reanalysis data is mainly distributed in the Pacific Ocean and the equatorial region of the Atlantic Ocean, the Northwest Pacific Ocean and the Northern Indian Ocean.
