Compound wind and precipitation (CWP) extreme events can result in increased socio-economic loss in coastal regions. This study found that climate change is expected to significantly increase precipitation extremes compared to wind extremes, leading to an increase in the likelihood of CWP events in coastal regions of the North Atlantic, East Asia, and South Asia.
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.
