For the first time, the connection between energetic in cloud pulse and terrestrial gamma‐ray flashes is confirmed in the Gamma-Ray Observation of Winter Thunderclouds experiment in Japan.
Charged by thunderstorms and other weather phenomena, the global electrical circuit connects the entire planet.
Thunderstorms present a variety of hazards, including emissions of ionizing radiation. An international group of scientists met at an Armenian observatory to share their findings.
The microphysics of the frequent, and frequently positive, lightning of Hokuriku winter clouds was investigated by systematic, in situ observation of individual precipitation particle type and charge.
As thunderstorm updrafts strengthen, electrification of clouds can heat the lower ionosphere, explaining prolonged disturbances to radio waves in the rarefied atmospheric layer.
Two lightning flashes were observed in the same location: One produced a bright gamma-ray flash with about 1000 counts per millisecond, but the other did not.

Satellite measurements confirm hundred-year-old observations collected by boat.
A new technique can remotely sense strong electrical fields within storm clouds.
