ENSO Signals in the Tropospheric and Stratospheric Temperatures: A Comparison among Different Datasets
对流层和平流层温度中ENSO信号的多种资料比较

Signals of global tropospheric and stratospheric temperature anomalies associated with ENSO events in boreal winter during the period of 1980-1999 are investigated by using the Microwave Sounding Unit(MSU) data.Results derived from five reanalysis datasets(ERA40,JRA25,NCEP1,NCEP2,and MERRA) are compared with the MSU data.The symmetric and asymmetric components of temperature anomalies associated with warm and cold episodes of ENSO are revealed.The MSU data are taken as a benchmark to evaluate the veracity o...
