Only then does a brilliant white lightning leader crawl slowly from the top of the cloud, reaching about 10% of the height of the gigantic jet before fading. They were first recorded on October 21, 1989, on a monochrome video of a thunderstorm on the horizon taken from the Space Shuttle as it passed over Australia. They last for only a few microseconds.

They are not related to lightning.[27]. "Full report on the uncontrolled free fall of a stratospheric balloon payload provoked by a Sprite", Fractal Models of Blue Jets, Blue Starters Show Similarity, Differences to Red Sprites, "The Role of the Space Shuttle Videotapes in the Discovery of Sprites, Jets, and Elves", Fractal models of blue jets, blue starters show similarity, differences to red sprites, "Chinese Science Bulletin 2012, Vol. Lightning phenomena: sprites, elves and blue jets There are different types of lightning (or electrical discharges) that occur well above the realm of the thunderstorms that we experience in the troposphere (the lowest layer of earth’s atmosphere as it runs as high as about 17 km above earth’s surface). TROLLs, (Transient Red Optical Luminous Lineaments) occur after strong sprites, and appear as red spots with faint tails, and on higher-speed cameras, appear as a rapid series of events, starting as a red glow that forms after a sprite tendril, that later produces a red streak downward from itself. Blue jets appear blue in color and go from the tops of clouds to a height of about 50 kilometers. Transient luminous events have also been observed in far-ultraviolet images of Jupiter's upper atmosphere, high above the altitude of lightning-producing water clouds.[1][2]. Sprites are flashes of bright red light that occur above storm systems. These were taken in a series of 1994 aircraft flights to study sprites. [18][19] The jets lasted under a second, with shapes likened by the researchers to giant trees and carrots. Months after the accident, an investigation concluded that a "bolt of lightning" traveling upward from the clouds provoked the incident. They often occur in clusters, lying 50 kilometres (31 mi) to 90 kilometres (56 mi) above the Earth's surface. They appear blue to the naked eye, can last for up to several hundreds of milliseconds and are cone-shaped. Examples may be seen in the clip 'Blue Jets & Blue Starters – the video', Phillips, T. (October 25, 2019). [24] From 35 miles, Holmes's video shows a blue streamer reach up from the top of a thunderstorm to the ionosphere, becoming red at the top. The preferred usage is transient luminous event (TLE), because the various types of electrical-discharge phenomena in the upper atmosphere lack several characteristics of the more familiar tropospheric lightning. Sprites have been witnessed thousands of times. [17] The jet was located above a thunderstorm over an ocean, and lasted under a second. The positive end of the leader network fills the negative charge region before the negative end fills the positive charge region, and the positive leader subsequently exits the cloud and propagates upward.

(Date of Image: Unknown), Credit: Victor Pasko, Penn State University. More about this Image The event was recorded using a monochrome, low-light video system, but the researchers all agree that the phenomena was seen visually as blue in color. The first video recording of a TLE was captured accidentally on July 6, 1989 when researcher R.C Franz left a camera running overnight to view the night sky. Scientists do not yet know if this is a new phenomenon. Also Available:Download the high-resolution JPG version of the image. "GJ event that was clearly recorded in eastern China (storm center located at 35.6°N,119.8°E, near the Huanghai Sea)". In a similar process to how blue jets form, the higher charge region is discharged by the leader network before the same occurs in the lower charge region, and one end of the leader network propagates upward from the cloud toward the ionosphere. Retrieved from, "Juno Discovers Sprites and Elves on Jupiter", "Sprites and Elves in the Atmosphere | Penn State University". They were later dubbed 'pixies'. Blue jet lightning. [11] They are also brighter than sprites and, as implied by their name, are blue in color. They are less than 100 meters across. Although jets are considered to be a type of upper-atmospheric lightning, it has been found that they are components of tropospheric lightning and a type of cloud-to-air discharge that initiates within a thunderstorm and travel upwards. Um bestimmt davon ausgehen zu können, dass die Auswirkung von Blue jet lightning tatsächlich nützlich ist, müssen Sie sich die Ergebnisse und Meinungen zufriedener Leute im Internet anschauen.Es gibt unglücklicherweise nur ziemlich wenige klinische Tests dazu, da diese ungemein kostspielig sind und üblicherweise nur Medikamente umfassen. The majority of these images, which include the first color imagery, are associated with a single thunderstorm. Gigantic jets between a thundercloud and the ionosphere. Blue starters are considered to be a weaker form of blue jets. Although jets are considered to be a type of upper-atmospheric lightning, it has been found that they are components of tropospheric lightning and a type of cloud-to-air discharge that initiates within a thunderstorm and travel upwards. (690 KB) Gigantic jets reach higher altitudes than blue jets, and the upper portion of the jet changes color from blue to red. Blue jets are believed to be initiated as "normal" lightning discharges between the upper positive charge region in a thundercloud and a negative "screening layer" present above this charge region. The storm center was located at 33°S, 60°W, near the city of Rosario. [6] The phenomena were named after the mischievous sprite, e.g., Shakespeare's Ariel or Puck,[7] and is also an acronym for Stratospheric/mesospheric Perturbations Resulting from Intense Thunderstorm Electrification. See also. Their green glow has been hypothesized by its observers to come from excited oxygen atoms, much as how auroras appear green, however, this is unconfirmed. The electrical contact may represent an important component of the global electrical circuit, says Basu. Blue jets are beams of blue light propagating from the tops of active thunderclouds up to altitudes of ∼50 km. P1.39 The Discovery of Red Sprites as an Opportunity For Informal Science Education. Blue jets develop on the tops of cloud formations at altitudes of 12 to about 26 miles high. This is the first image ever captured of blue jet lightning. They are not connected to lightning strikes. The two main types of jets are blue jets and gigantic jets. Close encounter with a gigantic jet. [31], Rare transient luminous events that occurs over tops of thunder storms, C. T. R. Wilson (1924) "The electric field of a thundercloud and some of its effects,", Earle R. Williams (November 2001) "Sprites, elves, and glow discharge tubes,". By 2007, fewer than a hundred images had been obtained. Upper-atmospheric lightning or ionospheric lightning are terms sometimes used by researchers to refer to a family of short-lived electrical-breakdown phenomena that occur well above the altitudes of normal lightning and storm clouds. [12], Blue starters were discovered on video from a night time research flight around thunderstorms[13] and appear to be "an upward moving luminous phenomenon closely related to blue jets. Blue jets occur much less frequently than sprites. In rund 40 km Höhe entstehen auf ähnliche Weise auch weiß-bläuliche, stichflammenähnliche Entladungen, „Blue Jets“ (dt. Gnomes are small, brief spikes of light that point upward from a thunderstorm cloud's anvil top, caused as strong updrafts push moist air above the anvil. Unsere Redakteure begrüßen Sie zu Hause auf unserem Testportal. [25] They occur in the ionosphere 100 km (62 mi) above the ground over thunderstorms. The global rate of TLE occurrence has been estimated from satellite (FORMOSAT-2) observations to be several million events per year. Blue starters are considered to be a weaker form of blue jets. [27][28], Pixies were first observed during the STEPS program during the summer of 2000, a multi-organizational field program investigating the electrical characteristics over thunderstorms on the High Plains. Their apparent speeds are in the range of 10 s to 100 s km/s. The terms red sprites and blue jets gained popularity after a video clip was circulated following an aircraft research campaign to study sprites in 1994. TLEs generally last anywhere from less than a millisecond to more than 2 seconds. The next known video recordings of a TLE were taken in 1989, when the Shuttle Mission STS-34 was conducting the Mesoscale Lightning Observation Experiment. „blaue Strahlen“), die Zehntelsekunden dauern und im Bereich der Stratosphäre aus der Wolkenoberdecke regelrecht herausspringen. 57 DOI: 10.1007/s11434-012-5486-3", https://spaceweatherarchive.com/2019/10/25/close-encounter-with-a-gigantic-jet/, ELVES, a primer: Ionospheric Heating By the Electromagnetic Pulses from Lightning, "Red sprites and blue jets explained - New discovery! C-sprites (short for “columniform sprites”) is the name given to vertical columns of red light. Walter A. Lyons and Michey D. Schmidt (2003). The acronym ELVES (“Emission of Light and Very Low Frequency perturbations due to Electromagnetic Pulse Sources”) refers to a singular event which is commonly thought of as being plural. The jet was initially observed to be traveling up at around 50,000 m/s (110,000 mph; 180,000 km/h) at a speed similar to typical lightning, increased to 160,000 and 270,000 m/s (360,000–600,000 mph; 580,000–970,000 km/h), but then split in two and sped upward with speeds of at least 2,000,000 m/s (4,500,000 mph; 7,200,000 km/h) to the ionosphere where it then spread out in a bright burst of light. The attribution of the accident to a sprite was made retroactively, since this term was not coined until late 1993. The color is believed to be due to a set of blue and near-ultraviolet emission lines from neutral and ionized molecular nitrogen. Huge Mystery Flashes Seen In Outer Atmosphere, http://webarchive.loc.gov/all/20020914103454/http://elf.gi.alaska.edu/, The Endless, Short film inspired by Sprite, https://en.wikipedia.org/w/index.php?title=Upper-atmospheric_lightning&oldid=1001571655, Short description is different from Wikidata, Articles with unsourced statements from February 2014, Creative Commons Attribution-ShareAlike License, This page was last edited on 20 January 2021, at 08:06. Wilson predicted that electrical breakdown should occur in the atmosphere high above large thunderstorms. It was taken at Arecibo Observatory in Puerto Rico, a National Science Foundation (NSF)-supported facility. [26] This refers to the process by which the light is generated; the excitation of nitrogen molecules due to electron collisions (the electrons possibly having been energized by the electromagnetic pulse caused by a discharge from an underlying thunderstorm). On October 21, 1989 TLE'S were recorded during the Shuttle orbits 44 and 45. A smaller variation of blue jets are According to Sunanda Basu, a program director in NSF's Division of Atmospheric Sciences (which funded the research), the video is the first ground-based evidence of a direct electrical discharge from a thundercloud top to the lower edge of the Earth's ionosphere. Upper-atmospheric lightning is believed to be electrically induced forms of luminous plasma. It was previously believed that blue jets were not directly related to lightning flashes, and that the presence of hail somehow led to their occurrence. TLEs have been captured by a variety of optical recording systems, with the total number of recent recorded events (early 2009) estimated at many tens-of-thousands. [27] They are about 200 meters wide, and have a maximum of 1 kilometer in height. [8] They normally are colored reddish-orange or greenish-blue, with hanging tendrils below and arcing branches above. Where blue jets are believed to initiate between the upper positive charge region and a negative screening layer directly above this region, gigantic jets appear to initiate between the upper positive and lower negative charge regions in the thundercloud. They are triggered by the discharges of positive lightning between the thundercloud and the ground. More about this Image A team of researchers at Arecibo captured video evidence from the ground of this lightning phenomenon known as blue jet. Unsere Redakteure haben uns der Aufgabe angenommen, Verbraucherprodukte verschiedenster Variante ausführlichst auf Herz und Nieren zu überprüfen, damit Sie zuhause schnell den Blue jet lightning sich aneignen können, den Sie zuhause haben wollen. [citation needed], On August 13, 2016, photographer Phebe Pan caught a clear wide-angle photo of a gigantic jet on a wide-angle lens while shooting Perseid meteors atop Shi Keng Kong peak in Guangdong province [21] and Li Hualong captured the same jet from a more distant location in Jiahe, Hunan, China. In contrast, other types of TLEs are not electrically connected with tropospheric lightning—despite being triggered by it. When reviewing the video taken, two finger-like vertical images appeared in two frames of the film. C-sprites exhibiting tendrils are sometimes called “carrot sprites”. Blue jet lightning - Wählen Sie dem Sieger der Tester. In contrast, other types of TLEs are not electrically connected with tropospheric lightning—despite being triggered by it. Other types of TLEs include sprite halos, ghosts, blue jets, gigantic jets, pixies, gnomes, trolls, blue starters, and ELVESs. On September 14, 2001, scientists at the Arecibo Observatory photographed a gigantic jet—double the height of those previously observed—reaching around 70 km (45 mi) into the atmosphere. [15] "Blue starters appear to be blue jets that never quite make it," according to Dr. Victor P. Pasko, associate professor of electrical engineering.[16]. Their color was a puzzle for some time, but is now believed to be a red hue.
