    摘要 2020年6-7月, 长江流域出现了创纪录的持续性特大暴雨. 观测资料表明, 与西北太平洋异常反气旋 (WNPAC) 相关的南风异常和与东北亚异常高压相联系的东北风异常交汇, 从而导致该持续性暴雨的发生. 进一步的观测和模式研究表明, 超强的 WNPAC 由赤道太平洋的 La Niña 型海温异常和热带印度洋的暖海温异常共同强迫产生. 与传统的中太平洋型 (CP) El Niño 的缓慢衰减不同, 2020 年初 CP El Niño 快速衰减, 到初夏演变为 La Niña. ENSO 的快速位相转换对 WNPAC 的形成发挥着关键的作用. 同时, 与 CP El Niño 相关的印度洋年际尺度海温异常叠加了年代际分量, 导致热带印度洋海温出现极端增暖. 数值试验表明, 热带印度洋和太平洋的热源对 WNPAC 的形成和维持均有贡献. 持续的东北亚高压异常则是中纬度静止 Rossby 波列的一部分, 由印度、 热带东太平洋和热带大西洋的热源共同强迫产生.
