Climate change is causing more frequent and intense precipitation extremes; however, these changes are difficult to project. This paper shows that observations of the increased frequency of extreme precipitation events over the past four decades can be used to reduce uncertainty in future climate model projections by 20–40%.

减少模拟暴雨发生增加的不确定性

气候变化正在导致更加频繁和强烈的极端降水；然而，这些变化很难预测。本文表明，对过去 40 年极端降水事件频率增加的观测可用于将未来气候模型预测的不确定性降低 20-40%。
