Gigantic jets with negative and positive polarity streamers
[1] The ISUAL gigantic jets (GJs) are categorized into three types from their generating sequence and spectral properties. Generating sequence of the type I GJs resembles that reported previously; after the fully developed jet (FDJ) established the discharge channel, the ISUAL photometers registered a peak that was from a return‐stroke‐like process. The associated ULF (ultra‐low‐frequency) sfer...
متن کاملBlue jets and gigantic jets
An overview of general phenomenology and proposed physical mechanisms of large scale electrical discharges termed ‘blue jets’ and ‘gigantic jets’ observed at high altitude in the Earth’s atmosphere above thunderstorms is presented. The primary emphasis is placed on summarizing available experimental data on the observed morphological features of upward jet discharges and on the discussion of re...
متن کاملRadar and lightning analyses of gigantic jet-producing storms
[1] An analysis of thunderstorm environment, structure, and evolution associated with six gigantic jets (five negative polarity, one positive) was conducted. Three of these gigantic jets were observed within detection range of very high frequency lightning mapping networks. All six were within range of operational radars and two-dimensional lightning network coverage: five within the National L...
متن کاملModel of UV flashes due to gigantic blue jets
Analysis of UV flashes observed by the UV detector on board the ‘Tatiana’ microsatellite suggests, based on their location, pulse width and energy of the source of the photons, that the flashes were generated by gigantic blue jets (GBJs). Presented in this paper is a numerical model of UV flashes due to a bunch of long streamers which form a leader, a prong such as that observed in a GBJ. Using...
متن کاملUpward electrical discharges observed above Tropical Depression Dorian
Observation of upward electrical discharges from thunderstorms has been sporadically reported in the scientific literature. According to their terminal altitudes, they are classified as starters (20-30 km), jets (40-50 km) and gigantic jets (70-90 km). They not only have a significant impact on the occupied atmospheric volumes but also electrically couple different atmospheric regions. However,...
