| 英文摘要 | Compound events (CEs) pose great challenges to disaster risk management as they can amplify risks to globally interconnected socio-economic systems. Identifying the hotspots of CEs and understanding their impact factors are critical for developing targeted climate adaptation strategies. Here, we analyzed 12 types of CEs, the pairwise combinations of seven different hazards (e.g, heatwave, drought and extreme precipitation) and one precondition (i.e., antecedent soil moisture), using global observations and reanalysis datasets of hydrometeorological variables across 520 major river basins during 1980-2019. The hotspots of CE were revealed based on their return periods, and the frequencies and seasonality of CEs in each continent were further explored. Lastly, the impact factors were determined among multiple atmospheric circulation variability modes using the odds ratio (OR) value. The results indicate that CE hotspots are mainly located in basin of Eastern Asia, Eastern North America, Western North America, the Mediterranean, and Northern Australia. Compound drought-heatwave events (D-H), compound antecedent soil moisture-extreme precipitation events (M-P) and spatially compound extreme precipitation events (spat.P) generally occur more frequently than other CEs, accounting for 12.97 similar to 27.05%, 5.22 similar to 22.92% and 15.68 similar to 21.13% of all compound events in the six continents, respectively. Among them, M-P and spat.P show strong seasonality only in Asia and the South-West Pacific. The El Ni & ntilde;o-Southern Oscillation (ENSO), Arctic Oscillation (AO), and North Pacific Pattern (NP) are the important impact factors of most CEs and are statistically associated with the occurrences of CEs, with 42.19 similar to 84.83%, 33.80 similar to 71.14%, and 0.79 similar to 25.35% of CEs occurring during ENSO, AO, and NP anomalies, respectively. These findings reveal the spatial heterogeneity of CEs driven mainly by atmospheric circulation anomalies, which could provide a basis for basin-scale climate risk management. |
