Characterisation of Thunderstorms with Multiple Lightning Jumps

open access: yesAtmosphere, 2022
Several works have shown that lightning jumps are precursors of severe weather in deep-convective thunderstorms. Since 2017, the Meteorological Service of Catalonia has operationally run an algorithm that identifies lightning jumps (LJs) in real time. It
