A detailed study of the complete sequence of VHF radiation events during intracloud (IC)
flashes in Florida has shown that IC flashes often have a bilevel structure connected by a single …

Radio frequency observations of cloud‐to‐ground lightning in Florida have been analyzed
to document a number of features of the lightning. The observations have been made using …

Observations of radio emissions from thunderstorms were made during the summer of 1996
using two arrays of sensors located in northern New Mexico. The first array consisted of …

A long-standing but fundamental question in lightning studies concerns how lightning is
initiated inside storms, given the absence of physical conductors. The issue has revolved …

Tropospheric thunderstorms have been reported to disturb the lower ionosphere, at altitudes
of 65–90 km, by convective atmospheric gravity waves 1 , 2 , 3 , 4 , 5 and by electric field …

A radio interferometer system is described which utilizes multiple baselines to determine the
direction of lightning radiation sources with an angular resolution of a few degrees and with …

Atmospheric electric field change (sferic) waveforms were detected at Los Alamos Sferic
Array stations in association with terrestrial gamma‐ray flashes (TGFs). Five TGF sferic …

The Los Alamos Sferic Array (LASA) recorded VLF/LF electric-field-change signals from over
ten million lightning discharges during the period from 1998 to 2001. Using the differential-…

We report the observation with the North Alabama Lightning Mapping Array (LMA) related to
a terrestrial gamma‐ray flash (TGF) detected by RHESSI on 26 July 2008. The LMA data …

This paper presents detailed comparisons between terrestrial gamma‐ray flashes (TGFs)
detected by the RHESSI satellite and the lightning processes observed by the Los Alamos …
