The climate pattern known as the El nino-southern Oscillation, or "ENSO" for short, is the biggest cause of large-scale climate variability in the tropics.
根据1951—1990年的北半球五个遥相关型的逐月强度指数以及南方涛动指数，建立了一个用于厄尔尼诺统计诊断的判别模型。
Based on the monthly data of five teleconnection pattern indices in Northern Hemisphere and SOI during the years of 1951 -1990, the discriminant model for diagnosing el Nino event is presented.
结果表明，南方涛动指数异常偏负(弱)以及厄尔尼诺事件的滞后影响对湘潭汛期洪涝的短期气候预报有很好的指示性。
The results showed that, anomalously small (weak) SOI and the lag effect of El Nino are good indications to the short-term climate prediction of Xiangtan flooding in flood period.
