Applicability Evaluation for Several Reanalysis Datasets Using the Upper-Air Observations over China
应用探空观测资料评估几类再分析资料在中国区域的适用性

Intercomparison of temperature and geopotential heights from ERA-40,NCEP/NCAR and NCEP/DOE reanalyzed products with the upper-air observations is made in eight regions over China.The results show that the differences of the mean values and interannual variations represented by the reanalysis and the observations exist mainly in the summer,especially obvious in southwestern and western China before the mid-1970s.The discrepancies of temperature are more obviously presented in the upper troposphere,but in ter...
