Abstract. Supercell thunderstorms are among the most hazardous and damaging weather phenomena in Europe. However; little information is available on the relationship between supercell morphology and environmental conditions in Europe. We dissect supercell morphology; the changes in environmental conditions; and the subsequent changes in associated hazardous weather using numerical simulations of the current and a warmer (+3 °C) climate at 2 km grid resolution. Comparing right- (RM) and left-moving (LM) storms; we find that RMs have a more coherent storm structure and larger high-intensity areas; and their motion deviates stronger from the mean flow compared to LMs. LMs occur in a narrower range of environmental conditions; namely in hotter and less stable environments compared to RMs. Overall; in the warmer climate the pre-storm environment becomes less stable; and deep-layer shear increases. Accordingly; hazards associated with supercells such as lightning; wind gusts; intense precipitation; and hail size all increase. RMs and LMs reach similar hazard intensities; while RMs tend to have larger high-hazard areas than LMs. The relative increase in hazard severity in the warmer climate is more pronounced for LMs; particularly for hail area and lightning intensity. A regional decomposition across Europe indicates LMs tend to occur in warmer; more unstable conditions than RMs; and that these regional differences are generally greater than the differences in storm environments between LMs and RMs.
