摘要： 分析了1999年与2003年我国北方地区夏季气温的变化特点和同期大气环流主要特征。结果表明:中国夏季气温变化有明显的年代际特征,这一特征与亚洲上空大气环流的年代际变化紧密相关,表明我国北方地区夏季气温异常一个很重要的原因或许是缘于气候年代际变化。2003年夏季中高纬环流形势呈两槽两脊的配置,与近十几年气候态分布刚好相反,因而从气候年代际变化的特征来看,2003年为预示年代际气候转型的征兆。

Abstract: Characteristics of temperature change and atmospheric circulation were analyzed in hot summer of 1999 and in cool summer of 2003 in Northern China.The results showed that obvious interdecadal variability of summer temperature was found,which was relevant to interdecadal variability of atmospheric circulation over the Asia.It also indicated that the important reason of summer temperature anomaly might be interdecadal variability of climate in Northern China.The circulation in mid-latitudes and high-latitudes in summer of 2003 took on two troughs and ridges,which was contrary to climate state of recent decades.The signs of climate shift were foreshowed in 2003 according to the characteristics of interdecadal variability.
