| 摘 要： | 应用ＥＯＦ（经验正交函数）迭代方案，考虑多时次历史资料，在全球海区海温与四川盆地气温非同步联系的基础上，以海温为预报因子进行了夏季气温的长期预报。结果表明：西太平洋高温区等关键海区海温的异常对未来四川盆地夏季气温变化有重要影响，由此建立的引入多时次海温的ＥＯＦ迭代长期温度预报方法，具有较强的预报能力

| Abstract: | Based on the empirical orthogonal function(EOF) iteration scheme,the multi time historical data and the asynchronous relationship between the SST over oceans and the air temperature in Sichuan basin,long term experiments of the prediction of the summer temperature have been done by using SST predictor.The results show that the anomalies of SST over key sea regions have important influences on the variation summer temperature in Sichuan basin.Thus,the established long term temperature forecast method with multi time SST predictors based on EOF iteration scheme has a definite capability for forecast. |
