Abstract
The most powerful optical emissions from lightning have been described
as “superbolts” since the 1970s. In 2019, Holzworth et al. (2019)
applied the superbolt label to the most energetic Radio Frequency (RF)
emissions measured by the World Wide Lightning Location Network (WWLLN).
In this study, we compare the WWLLN energies to optical measurements by
the photodiode detector (PDD) on the Fast On-orbit Recording of
Transient Events (FORTE) satellite and the Geostationary Lightning
Mappers (GLMs) on NOAA’s Geostationary Operational Environmental
Satellites (GOES) to assess whether WWLLN high energy events coincide
with optical superbolts. We find no overlap between traditional
superbolts and WWLLN high energy events. Optical superbolts are not
energetic to WWLLN, while WWLLN superbolts are not optically bright.
Additionally, the top WWLLN sources occur in a different meteorological
context than superbolts. Despite some similarities in their overall
global patterns of occurrence, WWLLN high energy events correspond to a
different phenomenon.
