Short summary

Supercell thunderstorms are among Europe's most damaging storms. Using high-resolution climate data, we compare left-moving (LM) and right-moving (RM) supercells. RMs have larger areas of intense rainfall, hail, and lightning, while LMs are smaller but can reach similar intensities and occur in warmer, less stable conditions. In a warmer climate, supercell hazards intensify, especially for LMs. A regional analysis shows how regional climates further influence storm conditions and hazards.
