英文摘要	Compound wind and precipitation extremes (CWPEs) can severely impact natural and socioeconomic systems. However, our understanding of CWPE future changes, drivers, and uncertainties under a warmer climate is limited. Here, by analyzing the event both on oceans and landmasses via state-of-the-art climate model simulations, we reveal a poleward shift of CWPE occurrences by the late 21st century, with notable increases at latitudes exceeding 50 degrees in both hemispheres and decreases in the subtropics around 25 degrees. CWPE intensification occurs across approximately 90% of global landmasses, and is most pronounced under a high-emission scenario. Most changes in CWPE frequency and intensity (about 70% and 80%, respectively) stem from changes in precipitation extremes. We further identify large uncertainties in CWPE changes, which can be understood at the regional level by considering climate model differences in trends of CWPE drivers. These results provide insights into understanding CWPE changes under a warmer climate, aiding robust regional adaptation strategy development. Concurrent wind and precipitation extremes (CWPEs), a typical case of compound weather events, can cause flooding and strong winds that can paralyze public transportation, trigger power outages, and destroy houses and shelters. Furthermore, CWPE over the ocean can endanger the shipment of goods and its logistics. Yet, our understanding of the projected changes, underlying drivers, and uncertainties under a warmer climate is limited. Here, analyzing for the first time CWPEs both on global oceans and landmasses allows us to reveal a poleward shift of CWPEs at the global scale in response to climate change. We show that changes in precipitation extremes play a dominant role in determining the future changes in the frequency and intensity of CWPEs. Furthermore, at the regional level, we reveal substantial uncertainties in projections due to differences between the used climate models. We illustrate that these uncertainties are due to model differences in trends of CWPE drivers and argue that they should be addressed explicitly in impact assessments for guiding the development of robust adaptation strategies. An intensification and poleward shift of compound wind and precipitation extremes (CWPEs) will occur in a warmer climate Most changes in frequency and intensity of CWPEs stem from changes in precipitation extremes Substantial uncertainties at the regional level in projections of CWPEs are due to structural model differences
