Despite being one of the most familiar and widely recognized natural phenomena, lightning
remains relatively poorly understood. Even the most basic questions of how lightning is …

The VHF Broadband Digital Interferometer developed by Osaka University has been
improved to allow continuous sampling over the entire duration of a lightning flash and to …

Lightning is a dangerous yet poorly understood natural phenomenon. Lightning forms a
network of plasma channels propagating away from the initiation point with both positively …

Lightning flashes develop as a bidirectional tree, with a negative and a positive end
propagating simultaneously into cloud charges of the opposite polarity. In recent years, this …

We report on a terrestrial gamma ray flash (TGF) that occurred on 15 August 2014 coincident
with an altitude‐triggered lightning at the International Center for Lightning Research and …

Despite the significant progress in the understanding of the phenomenon of lightning and
the physics behind it, locating and mapping its occurrence remain a challenge. Such …

The dissonant development of positive and negative lightning leaders is a central question
in atmospheric electricity. It is also the likely root cause of other reported asymmetries …

Using a high‐speed video camera operated at 150,000 frames per second, we have
documented the upward propagation of an initial positive leader from a 325 m …

We have been developing an LF sensor network called Broadband Observation network for
Lightning and Thunderstorm (BOLT), to image the structure of lightning discharges in 3D …

Simultaneous data from two interferometers separated by 16 km and synchronized within
100 ns were collected for a thunderstorm near Langmuir Lab on October 23, 2018. Analysis …
