Supplementary material for the paper "Thunderstorm Environments in Europe". - R code to reproduce the core analysis (reproducing_calculations.R) - Data for each domain (data_domain*.csv) - csv-files of the two tables in the paper (means_clusters.csv and means_domains.csv). - Domain definitions (domains.csv). - A precise variable description (era5_vars.csv) - README for more information. Summary of the corresponding paper: Two thunderstorm environments are described for Europe: Mass-field thunderstorms, which occur mostly in summer, over land, and under similar meteorological conditions, and wind-field thunderstorms, which occur mostly in winter, over the sea, and under more diverse meteorological conditions. Our descriptions are independent of static thresholds and help to understand why thunderstorms in unfavorable seasons for lightning pose a particular risk to tall infrastructure such as wind turbines.
