摘　　要：本文利用中科院大气物理研究所的两层大气环流模式（ＩＡＰ－ＧＣＭ Ⅱ）作了冬季赤道东太平洋地区海表水温月异常增暖时对大气环流及我国气候影 响的数值试验。结果表明，该处海表水温的异常增暖能引起中太平洋信风带Ｗａｌｋｅｒ 环流的改变并激发出中高纬度３０－５０天的低频振荡；当该异常结束后，其后效仍 会对我国的气候产生影响。By using the lAp two level atmospheric general circulation model (1Ap- GCM Ⅱ),The numerical experiment on the equatorial eastern Pacific SST monthly abnormal heat has been done to study the effect for the atmospheric circulation and the climate of　Chi- na. The results indicate that the SST monthly abnormality changes Walker Circulation,can induce 30-60 days low-frequency oscillation in middle and high latitude area,and When the abnormality had disappeared,the later-effect for climate of China shall also exist,the prima- ry character in most place of China is cooler and few rain,but in the east-north China is hot- ter.
