Abstract

This dataset provides the data needed to reproduce the results by Brunner et al. 2025. Namely, a list of days with spatially compounding drought-flood events with the corresponding weather regimes and a list of days with spatially compounding dry-wet events with the corresponding weather regimes.
These events were extracted from a large-sample dataset of 4299 catchments in Europe with streamflow and precipitation data for the period 1981-2020: Brunner, M., B. Anderson (2024). Hydrologic and meteorologic extremes and transitions for 4299 catchments in Europe, HydroShare, http://www.hydroshare.org/resource/41dac0a2caf24ce0924ec7fe35b27aa1.

This dataset provides the data needed to reproduce the results by Brunner et al. 2025 (WRR). Namely, a list of days with spatially compounding drought-flood events with the corresponding weather regimes and a list of days with spatially compounding dry-wet events with the corresponding weather regimes.
These events were extracted from a large-sample dataset of 4299 catchments in Europe with streamflow and precipitation data for the period 1981-2020: Brunner, M., B. Anderson (2024). Hydrologic and meteorologic extremes and transitions for 4299 catchments in Europe, HydroShare, http://www.hydroshare.org/resource/41dac0a2caf24ce0924ec7fe35b27aa1.
The raw weather regime data are available through Zenodo: Grams, C. M., Büeler, D., and Hauser, S. (2025). Year‐round North Atlantic‐European Weather Regimes [Dataset]. Zenodo. https://zenodo.org/records/17080146.
