Abstract: To gain a comprehensive view on the characteristics and changing trend of compound extreme climate events in the Changjiang River Basin, we systematically reviewed the progress of researches on definitions, classifications, indices, identification methods and historical results of compound events in the Changjiang River Basin based on a bibliometric analysis.The main conclusions are: ① Compound events can be defined as two or more events occurring simultaneously or successively, which may amplify the impact, or even lead to extreme consequences.Based on spatiotemporal combinations, 4 types of compound extreme climate events can be categorized in the Changjiang River Basin: same location-same time (e.g.compound dry and hot events, extensive cold-precipitation-freezing events), same location-different time (e.g.drought-flood abrupt alternations, flood-heatwave abrupt alternations), different location-same time, different location-different time.The former two types encompass relative richer research, and the last two types have been researched insufficiently.② The empirical way to identify a compound event is applying a certain index and a peak-over-threshold (POT) approach in both China and abroad; around 26 indices and more than 30 identification methods are frequently applied in the scientific literatures.③ Changjiang River Basin is a hotspot for compound events.Since the 21st century, flood-heatwave abruption alternation events have been increasing the fastest in frequency, followed by compound dry and hot events and drought-flood abrupt alternation events.The extensive cold-precipitation-freezing event does not show an evident increase but gets more extreme.④ Future research and business efforts should focus on improving the monitoring and assessment system for compound events in the Changjiang River Basin, exploring the interactions and relationships among various factors, and understanding the underlying weather systems, driving factors, and physical mechanisms to enhance predictive capabilities.Meanwhile, it is also suggested to reinforce the interdisciplinary research and impact assessment of compound events on sensitive sectors (e.g.water resources, electricity).
