For over a century, numerous undocumented reports have appeared about unusual large-scale luminous phenomena above thunderclouds and, more than 80 years ago, it was suggested that an electrical discharge could bridge the gap between a thundercloud and the upper atmosphere. Since then, two classes of vertically extensive optical flashes above thunderclouds have been identified—sprites and blue jets. Sprites initiate near the base of the ionosphere, develop very rapidly downwards at speeds which… Expand

Gigantic jets between a thundercloud and the ionosphere
TLDR
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. Expand
Upward electrical discharges from thunderstorms
Blue jets, gigantic jets, cloud-to-cloud discharges and cloud-to-ground lightning are all electrical discharges from thunderclouds. An analysis of numerical simulations and observations of theseExpand
Thunderstorm clouds may discharge directly to the ionosphere in spectacular luminous jets – the largest electric discharges of our planet
[1] Thunderstorm clouds may discharge directly to the ionosphere in spectacular luminous jets – the largest electric discharges of our planet. The properties of these “giants,” such as theirExpand
Upward electrical discharges observed above Tropical Depression Dorian
TLDR
Close-distance observation of seven upward discharges from thunderstorms including one starter, two jets and four gigantic jets above Tropical Depression Dorian indicates that all events are of negative polarity, suggesting they are initiated in the same thundercloud charge region. Expand
The properties of a gigantic jet reflected in a simultaneous sprite: Observations interpreted by a model
[1] Thunderstorm clouds may discharge directly to the ionosphere in spectacular luminous jets – the largest electric discharges of our planet. The properties of these “giants,” such as theirExpand
Gigantic jet discharges evolve stepwise through the middle atmosphere
TLDR
The first such images are reported, showing a step-wise evolution of gigantic jets during their rising phase, as magnetic field signals tracking the charge transfer and optical Geostationary Lightning Mapper data are matched unambiguously to the precisely timed final jump process in a gigantic jet.

Recent Results from Studies of Electric Discharges in the Mesosphere
The paper reviews recent advances in studies of electric discharges in the stratosphere and mesosphere above thunderstorms, and their effects on the atmosphere. The primary focus is on the spriteExpand
Thunderstorm charge structures producing gigantic jets
Gigantic jets are atmospheric electrical discharges that propagate from the top of thunderclouds to the lower ionosphere. They begin as lightning leaders inside the thundercloud, and the thundercloudExpand
Blue Jets: Upward Lightning
Blue jets are beams of blue light propagating from the tops of active thunderclouds up to altitudes of ∼50 km. They resemble tall trees with quasi-vertical trunk and filamentary branches. TheirExpand
A gigantic jet event observed over a thunderstorm in mainland China
Gigantic jet (GJ) is a type of large-scaled transient discharge which occurs above thunderstorms. It connects the thunderstorms and ionosphere directly. Compared with the other transient luminousExpand

Television Image of a Large Upward Electrical Discharge Above a Thunderstorm System
TLDR
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 and resembled two jets or fountains and was probably caused by two localizd electric charge concentrations at the cloud tops.

Blue Jets: their relationship to lightning and very large hailfall, and their physical mechanisms for their production
Abstract Blue jets are narrow cones of blue light that appear to propagate upward from the cloud tops at speeds of about 100 km/s to terminal altitudes of about 40 km ( Wescott et al. 1995 ). In thisExpand
