| 摘 要： | 利用1951～2000年我国西北干旱、半干旱区地温、气温和表面风场逐日4个时次（北京时间2、8、14和20时）的台站观测资料，以及NCEP/NCAR和ERA-40再分析资料，计算并比较了在我国西北地区春夏季感热输送的差异。分析结果表明:NCEP/NCAR和ERA-40的感热输送再分析资料都能显示出我国西北地区是欧亚大陆上的感热中心之一。从年代际时间尺度上，ERA-40再分析资料的感热资料更接近于实际台站观测资料计算得到的感热资料。

| Abstract: | 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. |
