Estimates of lightning ground flash density in Australia and its relationship to thunder-days
A method of deriving lightning ground flash density from CIGRE lightning flash counter registrations based on the detection efficiency of the instrument, independent of the latitudinal variation of cloud flash-to-ground flash ratio is presented.

Cloud-to-ground lightning and Mesoscale Convective Systems [PDF]
This work analyzes some physical and microphysical properties of Mesoscale Convective Systems (MCSs) and cloud-to-ground lightning. Satellite data from the GOES-10 infrared and NOAA-18 and TRMM microwave channels and lightning information from the ...

Effects of Side Bileaders on Parent Positive Leader
Abstract Side bileaders are commonly induced near a progressing positive leader, yet their effects on the parent positive leader remain poorly understood. Here we investigate their effects by combining high‐speed video with LF/VLF lightning channel mapping.

Lightning mapping observations of downward lightning flashes to wind turbines [PDF]
Negative downward leaders that produced lightning strokes to wind turbines are identified by means of the Lightning Mapping Array data of the Ebro Valley Laboratory (NE Spain). Four cases are analyzed together with weather radar imagery.

Event‐Level Attribution of Wildfire Ignition Cause: A Machine‐Learning Approach
Abstract Wildfire ignition causes, namely human or lightning, largely determine fire behavior and impacts, but are sparsely reported worldwide. Event‐level fire causes have been inferred regionally using high‐accuracy lightning observations, but global generalization remains limited.

Rapid evolution of energetic lightning strokes in Mediterranean winter storms
The occurrence of winter lightning concentrates in a few specific regions in the world, including the Mediterranean, where electromagnetic signatures of this interesting dangerous phenomenon have not yet been studied in detail. We investigate the initial

Fast Breakdowns Observed in the Initial Leaders of Two Energetic Compact Strokes
Abstract We have observed 1 fast positive breakdown (FPB) and 20 fast negative breakdowns (FNBs) for the first time in the initial leader of two energetic compact strokes (ECSs) using a broadband interferometer. It was found that the FPB propagated upward over a distance of 30 m with a speed of 1.2×107m/s $1.2\times {10}^{7}\mathrm{m}/\mathrm{s ...
