风和降水复合（CWP）极端事件会导致沿海地区社会经济损失显著增加。本研究利用耦合模式相互比较项目的模式输出，在全球范围内受热带气旋影响的沿海地区，调查了气候变化对CWP事件的潜在影响。我们确定了极端风和降水事件之间依赖性较高的全球热点。在气候变化下，结果显示，与个别风极端事件相比，降水极端事件大幅增加。气候变化下的CWP事件的可能性表明，在北大西洋，东亚和南亚的大多数沿海地区增加（约40%-50%）。这项研究的结果可以帮助确定气候变化下的热点地区，并进一步帮助减少未来灾害对脆弱沿海地区的影响。
Compound wind and precipitation (CWP) extreme events can cause a significant increase in socio‐economic loss in coastal regions. This study investigated the potential impact of climate change on CWP events using Coupled Model Intercomparison Project model outputs for the coastal areas impacted by tropical cyclones on a global scale. We identified global hotspots of higher dependence between extreme wind and precipitation events. Under climate change, the results show a substantial increase in precipitation extremes compared to individual wind extreme events. The likelihood of CWP events under climate change indicates an increase (about 40%–50%) in most coastal regions in North Atlantic, East, and South Asia. The results of this study can help to identify hotspot regions under climate change and further assist in minimizing the impact of future disasters in vulnerable coastal areas.
