Cover Story: In the climate change context, lightning-ignited wildfires are an increasing hazard in the Mediterranean Basin. Although lightning activity can be predicted, the challenge remains in forecasting the thunderstorm’s probability of ignition. The ERA5 reanalysis was used to select the best predictors to forecast lightning-ignited wildfires. The results show that they tend to be associated with dry thunderstorms, characterised by weak updrafts, high-based clouds, and relatively dry air at lower levels, favouring the occurrence of “dry lightning”, which is associated with less than 2.5 mm of rainfall. Comparison with similar studies indicates a considerable degree of universality, suggesting the potential of these thermodynamic and kinematic parameters to be applied more widely. View this paper
