摘    要:采用NCEP/NCAR、ECMWF两种再分析资料,分析了1979-1989年纬向平均经向风(υ↑-])及质量流函数(ψ↑-)的差异。结果表明,ECMWF资料存在明显的Hadley双层结构,NCEP/NCAR资料则未见明显的Hadley双层结构。此项研究结果虽不能证明Hadley双层结构是否客观存在,但表明低纬大气环流研究中资料选用直接影响研究结果。

关 键 词:NCEP/NCAR再分析资料  ECMWF再分析资料  Hadley环流双层结构  差异分析

Abstract:The NCEP/NCAR and ECMWF reanalysis data were used to analyze the difference of zonally mean meridional wind and mass stream functions between the two data sets from 1979 to 1989. The result shows that the Hadley cell in the ECMWF data had an obvious bi-level structure, but there was no such phenomena in the NCEP/NCAR data. Although this paper cannot verify whether Hadley cell actually has a bi-level structure or not, it does clarify that the choice of data has direct effect on the research result of the low-latitude general circulation.
Keywords:NCEP/NCAR reanalysis data  ECMWF reanalysis data  bi-level structure of Hadley cell  contrast analysis
