实际气候系统中包含了行星尺度、洋盆尺度和局地海气相互作用的过程.一层大气的Zebiak-Cane(ZC)模式仅仅描写了局地海气相互作用.于是,行星尺度的Hadely环流异常和洋盆尺度的Walker环流异常需要引进到ZC模式中.通过在ZC模式中引进Hadley异常的改进,结果表明改进的模式不仅能对1970～1990年,而且也能对1991～1995年的赤道东太平洋海温异常作出提前9～10个月的预报. The actual climate system includes the processes of planetary scale, oceanic scale and local ocean-atmosphere interaction. The first-level atmospheric Zebiak-Cane (ZC) model only describes the local sea-air interaction. Thus, the planetary-scale Hadely circulation Abnormal and oceanic scale Walker circulation anomalies need to be introduced into ZC model.By introducing Hadley anomaly improvement in ZC model, the results show that the improved model not only can be used for the years from 1970 to 1990, but also for the equatorial east of 1991 ~ 1995 Pacific SST anomaly to make 9 to 10 months in advance forecast.
