An image of an unusual luminous electrical discharge over a thunderstorm 250 kilometers from the observing site has been obtained with a low-light-level television camera. The discharge began at the cloud tops at 14 kilometers and extended into the clear air 20 kilometers higher. The image, which had a duration of less than 30 milliseconds,resembled two jets or fountains and was probably caused by two localizd electric charge concentrations at the cloud tops. Large upward discharges may create… 

Upward Electrical Discharges From Thunderstorm Tops

A variety of storm top electrical discharges have been observed using several types of low-light imagers, film, and the human eye. Recently, a video recorded an unprecedented, bright blue upward

Electrical discharge from a thundercloud top to the lower ionosphere

A video recording of a blue jet propagating upwards from a thundercloud to an altitude of about 70 km is reported, taken at the Arecibo Observatory, Puerto Rico, to speculate that it may be common and therefore represent an unaccounted for component of the global electric circuit.

Elves : Lightning-induced transient luminous events in the lower ionosphere

Observations of optical phenomena at. high alti- tude a, bove thunderstorms using a multichannel high-speed photometer and image intensified CCD cameras were carried out at Yucca Ridge Field Station

Gigantic jets between a thundercloud and the ionosphere

Observations of five gigantic jets that establish a direct link between a thundercloud and the ionosphere at 90 km elevation indicate that the extremely-low-frequency waves were generated by negative cloud-to-ionosphere discharges, which would reduce the electrical potential between ionosphere and ground.

As part of a collaborative campaign to investigate Transient Luminous Events (TLEs) over South America, coordinated optical, ELF/VLF, and lightning measurements were made of a mesoscale thunderstorm

Lightning‐driven electric fields measured in the lower ionosphere: Implications for transient luminous events

[1] Transient luminous events above thunderstorms such as sprites, halos, and elves require large electric fields in the lower ionosphere. Yet very few in situ measurements in this region have been

The Lightning Discharge

It is considered that the potential required to cause a lightning discharge is only a small percentage of that hitherto believed necessary, namely, of the order of 5 x 107 volts as compared with Wilson's 1 x 109 to 6 x 109 volts.
