Abstract The intensification of compound hot-dry events due to climate change is a pressing concern, underscoring the need for precise analysis. However, impact different dry indicators on projections these has not been quantitatively evaluated, nor its importance compared with other sources uncertainty. Here we examine sensitivity projected changes in indicators. We use data from 22 Coupled Model Intercomparison Project Phase 6 (CMIP6) models characterize global conditions based precipitation, runoff, soil moisture, and multivariate index combining variables through trivariate copulas. Our findings reveal large differences likelihood across While model uncertainty remains primary source event projections, associated also substantial, surpassing scenario specific regions.

Under climate change, China faces intensifying compound extreme events with serious socio-economic ramifications, yet their future variations remain poorly understood. Here, we estimate historical hotspots and changes of two typical events, i.e., sequential heatwave precipitation (SHP) concurrent drought (CDH) across China, leveraging a bivariate bias correction method to adjust projections from global models. Results show substantial increases in frequency, duration, magnitude for both the durations projected double nationwide. The are more evident under higher emission scenarios, could be largely underestimated if neglecting variable dependence during process. will escalate exposure China's major urban clusters, among which Guangdong-Hong Kong-Macao face highest risk. Our findings underscore necessity carbon controls, call adaptive measures mitigate threats induced by rising hazards changing climate.

Compound dry and hot events (CDHEs) are among the most destructive compound extremes. Under global warming, changes in precipitation, temperature their dependence make profound contributions to CDHEs. In this paper, of these three factors explicitly quantified based on a novel mathematical method. Specifically, time series precipitation employed identify CDHEs then attributed by using partial derivatives-based sensitivity analysis. Based Climatic Research Unit Time-Series (CRU TS), case study is devised for major river basins (MRBs) world. The results highlight that from period 1921-1970 1971-2020, did occur more frequently across MRBs. tended largest contribution, followed between temperature.
