Joint Seminar: From Supercell Climate Trends to Heatwave-Linked Thunderstorm Outbreaks: Severe Convection Across Europe
Supercell thunderstorms and severe convective outbreaks pose significant hazards in Europe. This seminar highlights two aspects: supercell trends under climate change and the relationship between convective outbreaks and heatwaves. Kilometer-scale climate simulations reveal widespread supercell activity across Europe, with hotspots near mountain ranges. A future climate simulation indicates increased supercell activity in central and eastern Europe, a shift to higher altitudes, and reduced activity in western Europe. These findings underscore the potential impacts of climate change on severe convection. Looking into large-scale drivers of severe convection, reanalysis data show that most severe convective environments are linked to warm anomalies and slow upper-level wave patterns, often related to downstream heatwaves. Conversely, a majority of heatwaves are associated with upstream severe convection, potentially amplifying their intensity. These insights indicate shared large-scale drivers and feedbacks shaping Europe's severe weather.
