Sprite discharges on Venus and Jupiter‐like planets: A laboratory investigation
[1] Large sprite discharges at high atmospheric altitudes have been found to be physically similar to small streamer discharges in air at sea level density. Based on this understanding, we investigate possible sprite discharges on Venus or Jupiter‐like planets through laboratory experiments on streamers in appropriate CO2‐N2 and H2‐He mixtures. First, the scaling laws are experimentally confirm...
متن کاملSprite discharges on Venus, Jupiter and Saturn: a Laboratory Investigation in Planetary Gas Mixtures
Lightning was detected on several planets in the solar system, where it could also produce sprites in the upper layers of these atmospheres. Large sprite discharges at mesospheric altitudes on Earth have been found to be physically similar to streamer discharges in air at sea level density. Based on this understanding, we investigate possible sprite discharges on the Gas Giant planets and on Ve...
متن کاملDetectability of sprites above lightning storms on the giant planets
Large sprite discharges at mesospheric altitudes on Earth have been found to be physically similar to streamer discharges in air at sea level density. Based on this understanding, we investigate possible sprite discharges on the Gas Giant planets through laboratory experiments on streamers in H2-He gas mixture. Streamer diameters, radiance, and emission spectra are investigated and compared to ...
متن کاملOn the inception of streamers from sprite halo events produced by lightning discharges with positive and negative polarity
[1] In the sprite halo events produced by cloud‐to‐ground lightning discharges, the spatial offsets, long delays, and polarity asymmetry related to the inception of sprite streamers are yet to be explained consistently with observations. In the present work, we use a two‐dimensional model and a high‐resolution one‐dimensional plasma fluid model accounting for electron impact ionization, dissoci...
متن کاملRed sprite discharges in the atmosphere at high altitude: the molecular physics and the similarity with laboratory discharges
An overview of the general phenomenology and physical mechanism of large-scale electrical discharges termed ‘sprites’ observed at high altitude in the Earth’s atmosphere above thunderstorms is presented. The primary emphasis is placed on summarizing available experimental data on various emissions documented to date from sprites and interpretation of these emissions in the context of similar da...
