“…A narrow cut‐off low over the center‐eastern of France evolving into a quasi‐omega atmospheric pattern on 30 August 2022, favored the development of a short‐wave trough over northeastern Spain (Figure S1 in Supporting Information ). The supercell storm developed in the Pyrenees due to orographic lift and highly unstable environment (Farnell et al., 2023). The SST and the SST anomaly reach the highest values in comparison to the climatology of a 3‐week percentile rank centered on the event day (Figures 1b and 1c).…”

A severe hailstorm that occurred in Spain on 30 August 2022, caused material and human damage, including one fatality due to giant hailstones up to 12 cm in diameter. By applying a pseudo‐global warming approach, here we evaluate how a simultaneous marine heatwave (and anthropogenic climate change) affected a unique environment conductive to such giant hailstones. The main results show that the supercell development was influenced by an unprecedented amount of convective available energy, with significant contributions from thermodynamic factors. Numerical simulations where the marine heatwave is not present show a notable reduction in the hail‐favorable environments, related mainly to modifications in thermodynamic environment. Our simulations also indicate that the environment in a preindustrial‐like climate would be less favorable for convective hazards and thus the hailstorm event would likely not have been as severe as the observed one, being possible to perform a novel attribution of such kind.
