Small‐Scale Discharges Observed Near the Top of a Thunderstorm
GEOPHYSICAL RESEARCH LETTERS
24 april 2023
Olaf Scholten, Brian Hare, Joseph R. Dwyer, Ningyu...
We have used the LOw‐Frequency ARray (LOFAR) to image a few lightning flashes during a particularly severe thunderstorm. The images show an e...
Ultra‐Slow Discharges That Precede Lightning Initiation
GEOPHYSICAL RESEARCH LETTERS

Christopher Francis F. Sterpka, Joseph R. Dwyer, N...
We report on ultra‐slowly propagating discharge events with speeds in the range 1–13 km/s, much lower than any known lightning pro...
The Meter-Scale Structure of Recoil Leaders as Observed by LOFAR
PHYSICS OF STREAMERS, LEADERS, AND THE LIGHTNING DISCHARGE: HIGH-RESOLUTION OBSERVATIONS AND MODELING II ORAL
atmospheric and space electricity | 14 december 2022
Brian Hare, Olaf Scholten, Stijn Buitink, Joseph R...
The propagation mechanism of dart leaders and recoil leaders (dart leaders that do not reach ground) is poorly understood. We will present multiple re...
