摘    要:采用SSTA、风场、OLR以及中国160站降水、气温等资料,根据赤道中东太平洋SSTA的逐季变化,将ENSO循环过程在夏季的位相分为5种型。对其相应的Walker环流的显著性检验发现,A型与C型夏季的差别最为显著。夏季要素场合成分析发现。A型与C型的情形差别最明显。A型夏季的要素场与弱夏季风年的相似;C型夏季的要素场与强夏季风年的相似。

关 键 词:厄尔尼诺  夏季  位相  季风  降水  气温

Abstract:In terms of global SSTA,wind,OLR data and precipitation,temperature in China,five catalogues are defined of the phases in summer of ENSO cycle based on seasonal SSTA in equatorial central and eastern Pacific.It is found that the difference in Walker circulation is the most significant between Type A ang Type C.Further evidents show that the Walker circulation,the Hadely cell,subtropical high in western Pacific and the east Asian monsoon are week(strong) in summers of Type A(C),with lower(higher) temperature and more(less) rainfall in the reaches of the Yangtze River.
Keywords:ENSO cycle  phase  east Asian summer monsoon  precipitation  temperature
