A Comparison of NCEP/NCAR, ERA-40 Reanalysis and Observational Data of Sensible Heat in Northwest China
比较NCEP/NCAR和ERA-40再分析资料与观测资料计算得到的感热资料的差异

The sensible heat in Northwest China are compared by using NCEP/NCAR, ERA-40 reanalysis and observational data during 1958-2000. The analyzed results show that the one of most center for sensible heat is in Northwest China by NCEP/NCAR, ERA-40 reanalysis data. The ERA-40 reanalysis data is more close to observational data in interdecadal time scale than that of NCEP/NCAR reanalysis data.
