从长期预报角度出发，分析了厄尔尼诺和反厄尔尼诺事件这一短期气候异常的强信号与黄河中游汛期暴雨的关系。结果表明：在厄尔尼诺最大影响年相当暴雨日数较少，在反厄尔尼诺最大影响年相当暴雨日数较多。
From the perspective of long-term forecasting, this paper analyzes the relationship between El Niño and Anti-El Nino events, a strong signal of short-term climatic anomalies and torrential rain over the middle reaches of the Yellow River. The results show that the number of rainstorm days in the year with the largest impact of El Niño is relatively small, and the number of rainstorm days with the largest impact in the anti-El Niño season is relatively large.
