“…The Spanish Supercell Data set (Martín et al., 2021) and the European Severe Weather Database (ESWD; Dotzek et al., 2009) observations are here used to analyze a climatological background and uniqueness of the Gerona giant hail event. The Spanish Supercell Data set (Calvo‐Sancho et al., 2022; Martín et al., 2021) encompasses the period from 2011 to 2022 with a total of 286 documented supercell observations. The data set includes Supporting Information to the events whenever available, such as hail diameter or tornado intensity.…”

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.

“…Otras organizaciones, como ESTO-FEX (European Storm Forecast Experiment), TORRO (Tornado and Storm Research Organization) o SevereWeatherEurope, dedican cada vez más recursos al seguimiento y predicción de los eventos supercelulares. En España existen múltiples casos de estudio de situaciones supercelulares [7][8][9][10][11][12][13][14][15][16][17], pero hasta el año 2020 no se disponía de estudios sistemáticos de caracterización ni climatología alguna de este tipo de tormentas [18]. Sin embargo, entre los aficionados a los fenómenos meteorológicos adversos, los cazatormentas vienen haciendo un gran trabajo colaborativo de seguimiento y constatación de los casos ocurridos en nuestro país desde hace aproximadamente 15 años.…”

“…Gracias a esa colaboración, en el foro de Meteored (https://foro.tiempo.com/tiempo-severo-b89.0/) se ha generado una base de datos con los eventos supercelulares registrados desde el año 2003, y de manera sistemática desde 2011, hasta el 2020. Se puede encontrar una descripción de ese trabajo colaborativo en Martín et al [18], donde se describe la base de datos de supercélulas registradas y se lleva a cabo un análisis de la distribución espacial de supercélulas en España en el periodo 2014-2019.…”

Abstract. Severe convective storms, in particular supercells, are occasionally responsible for a large number of property losses and damage in Spain. This paper aims to study the synoptic configurations and pre-convective environments in a dataset of 262 supercells during 2011–2020 in Spain. The events are grouped into supercells with hail (diameter larger than 5 cm) and without hail and the results are compared. ERA5 reanalysis is used to study the synoptic configurations and proximity atmospheric profiles related to the supercell events at the initial time. In addition, temperature, convective available potential energy, convective inhibition, lifting condensation level, level of free convection, height of freezing level, wind shear and storm-relative helicity are obtained for each event. Results show that supercells are more frequent on the Mediterranean coast during the warm season. Some of the variables analyzed present statistically significant differences between hail and non-hail events. In particular, supercells with hail are characterized by higher median values of most-unstable convective available potential energy than supercells without hail.
