摘要
利用一个耦合海气模式，用数值试验方法分析了１９８２／１９８３ＥＮＳＯ期间的暖池和赤道辐合带（ＩＴＣＺ和ＳＰＣＺ）的相互作用对大气表面流场和散度场的影响。结果指出，ＥＮＳＯ高峰期和成熟期ＳＰＣＺ比ＩＴＣＺ更重要（即ＥＮＳＯ高峰期和成熟期ＳＰＣＺ与暖池相互作用比ＩＴＣＺ与暖池相互作用更强烈）；ＥＮＳＯ的形成初期和衰减期ＳＰＣＺ和ＩＴＣＺ同样重要．
By using a linear and stationary atmospheric model (Luo and Jiang, 1994, Zebiax and cane , 198z) and the initial d4ta coming from zebiak and bine (1987), the innuence of interaction between the shift of the warm POol and that of the equatorial covergence zone (ITCZ and SPCZ) on atmospheric surface stream field and divergence field during 1982/1983 ENSO is analysed with the numerical experiments. The resultS show that SPCZ is more important than ITCZ during the developing and mature stages of ENSO. The interaction between the warm pool and SPCZ is stronger than that between the warm pool and ITCZ In the two singes, SPCZ is as important as ITCZ during the initial and collapsing phases.
