Analysis of Blue Corona Discharges at the Top of Tropical Thunderstorm Clouds in Different Phases of Convection
Dimitriadou, Krystallia; Chanrion, Olivier; Neubert, Torsten; Protat, Alain; Louf, Valentin; Heumesser, Matthias; Husbjerg, Lasse; Köhn, Christoph; Østgaard, Nikolai; Reglero, Victor (Journal article; Peer reviewed, 2022)We report on observations of corona discharges at the uppermost region of clouds characterized by emissions in a blue band of nitrogen molecules at 337 nm, with little activity in the red band of lightning leaders at 777.4 ... -
Observation of Blue Corona Discharges and Cloud Microphysics in the Top of Thunderstorm Cells in Cyclone Fani
Li, Dongshuai; Neubert, Torsten; Husbjerg, Lasse Skaaning; Zhu, Yanan; Chanrion, Olivier; Lapierre, Jeff; Luque, Alejandro; Köhn, Christoph; Heumesser, Matthias; Dimitriadou, Krystallia; Stendel, Martin; Kaas, Eigil; Olesen, Emilie Petrea; Liu, Feifan; Østgaard, Nikolai; Reglero, Víctor (Journal article; Peer reviewed, 2023)Blue corona discharges are often observed at the top of thunderclouds. They are bursts of streamers, but the cloud conditions that enable them are not well known. Here we present observations by the Atmosphere-Space ... -
Observations of Blue Corona Discharges in Thunderclouds
Husbjerg, Lasse Skaaning; Neubert, Torsten; Chanrion, Olivier; Dimitriadou, Krystallia; Li, Dongshuai; Stendel, Martin; Kaas, Eigil; Østgaard, Nikolai; Reglero, Victor (Journal article; Peer reviewed, 2022)Blue electric streamer discharges in the upper reaches of thunderclouds are observed as flashes of 337.0 nm (blue) with faint or no emissions of 777.4 nm (red). Analyzing 3 years of measurements by the Atmosphere-Space ... -
Spectral Observations of Optical Emissions Associated With Terrestrial Gamma-Ray Flashes
Heumesser, Matthias; Chanrion, Olivier; Neubert, Torsten; Christian, Hugh J.; Dimitriadou, Krystallia; Gordillo-Vazquez, Francisco J.; Luque, Alejandro; Pérez-Invernón, F. J.; Blakeslee, Richard J.; Østgaard, Nikolai; Reglero, Victor; Köhn, Christoph (Journal article; Peer reviewed, 2021)The Atmosphere-Space Interactions Monitor measures Terrestrial Gamma-Ray Flashes (TGFs) simultaneously with optical emissions from associated lightning activity. We analyzed optical measurements at 180–230, 337, and 777.4 ...
