摘　　要：本文应用中国科学院大气物理研究所设计的两层大气环流模式（ＩＡＰ－ＡＧＣＭ）研究了夏季赤道东太平洋地区负的海温异常对全球大气及赤道太平洋地区和东亚局地短期气候变化的影响，着重分析了海温异常（ＳＳＴＡ）所造成的降水、高度场、风场以及赤道太平洋地区海表感热和潜热输送等一些物理场的异常，并对赤道东太平洋海温异常影响全球及赤道太平洋和东亚局地短期气候变化的物理机制进行了探讨，得到了一些有意义的结果。By using the two-level atmospheric cireulation model develops in the bottlte of Atmospheric Physics,ChineSe Academy of Scienese (IAP-AGCM), the influence of negative sea-surface temperature anomalies (SSTA)in the eastern eqUatorial Padfic in summer upon the global atmospherac circuation and the regional short-mngeclimate changes in the eqUatorial Pacific and East Asia is studied with special attention to the anomalies of some simulatal variables such as the latent flux and sensible flux at the sea surface in the equatorial Padfic precipitanongtopotential height andwind and so on. How the SSTA in the eastern eqUatorial P￣in summer summer affects the gabaland regional short-range close changes is also studied. Some medngful results are obtained.
