Return stroke peak current versus charge transfer in rocket‐triggered lightning [PDF]

Journal of Geophysical Research: Atmospheres, 2010
We examined data on 117 return strokes in 31 rocket‐and‐wire‐triggered lightning flashes acquired during experiments conducted from 1999 through 2004 at the International Center for Lightning Research and Testing at Camp Blanding, Florida, in order to compare the peak currents of the lightning return strokes with the corresponding charges transferred ...

D‐Region Changes and Wave Activity Detected From Unusually Strong VLF Anomalies Associated With the January 2022 Tonga Volcanic Eruption

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract We present unusually strong daytime signal amplitude anomalies of 11.1 dB on JJI and 12.6 dB on VTX very low‐frequency (VLF) transmitter signals recorded at Suva, Fiji, due to the powerful Hunga Tonga–Hunga Ha'apai (HTHH) volcanic eruption (VE) on 15 January 2022 around 04:00 UT.

Discussions on a long gap discharge to an EHV transmission tower by a rocket triggered lightning experiment [PDF]

The triggered lightning experiments using a rocket have been carried out on a winter mountain in Japan since 1986. For the four years from 1986 to 1989, 39 rockets were launched and 19 of them triggered lightning strikes.

Pandemic, paternalism, and the (im)possibilities of citizenship in China

American Ethnologist, Volume 52, Issue 4, Page 401-413, November 2025.
Abstract How did Chinese citizens imagine their political subjectivity under the zero‐COVID regime? Our patchwork netnography of social media discussions (2020–22) analyzes how China's pandemic governance generalized and intensified “biopolitical paternalism”—a mode of rule that fused security, care, and economic rationality under the figure of a ...

Broad band interferometric measurement of rocket triggered lightning in Japan

Geophysical Research Letters, 1997
A broad band interferometer to investigate the location of radio sources due to lightning flashes in two dimension has been manufactured and evaluated during the Rocket Triggered Lightning Experiment in Japan. Having high digitization rate, a broad band interferometer is not able to record the entire radiation process emitted by a lightning discharge ...

Correlated Lightning Mapping Array (LMA) and Radar Observations of the Initial Stages of Florida Triggered Lightning Discharges [PDF]

, 2012
We characterize the geometrical and electrical characteristics of the initial stages of nine Florida triggered lightning discharges using a Lightning Mapping Array (LMA), a C-band SMART radar, and measured channel-base currents.

Characterizing upward lightning with and without a terrestrial gamma-ray flash

, 2018
We compare two observations of gamma-rays before, during, and after lightning flashes initiated by upward leaders from a tower during low-altitude winter thunderstorms on the western coast of Honshu, Japan.

Downward Terrestrial Gamma‐Ray Flash Associated With a Positive Cloud‐to‐Ground Lightning Flash

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract We observed a terrestrial gamma‐ray flash (TGF) shortly after the return stroke in a positive cloud‐to‐ground (+CG) flash during a 2025 winter thunderstorm in the Hokuriku region of Japan. The event was observed with multiple gamma‐ray detectors and radio antenna systems.
