There is anecdotal evidence of sightings of upper atmosphere lightning, or Transient Luminous Events (TLEs), at least as far back as the 1730s, while proper visual reports of sightings go back to 1886. They often occur in clusters, lying 50 kilometres (31 mi) to 90 kilometres (56 mi) above the Earth's surface. It is headquartered in Redwood City, California. China's big jet – not the passenger kind. The phenomena were named after the mischievous sprite, e.g., Shakespeare's Ariel or Puck, and is also an acronym for Stratospheric/mesospheric Perturbations Resulting from Intense Thunderstorm Electrification. It was previously believed that blue jets are not directly related to lightning flashes, and that the presence of hail somehow leads to their occurrence. They're rather rare. The upper part resembles a sprite while the lower half is jet-like. Other types of TLEs include sprite halos, blue jets, gigantic jets, blue starters, and ELVESs. There are several types of TLEs, the most common being sprites. Special viewing sites are needed to see sprites, as they always hide above thunderstorms. They bear whimsical names like sprites, elves, gnomes and more. Sprites occur a fraction of a second after strong lightning strokes, soaring upward to an altitude of nearly 100 kilometers. If ordinary lightning seems pretty ordinary, upper atmosphere lightning is something else – an entire ZOO of various types of upper atmosphere electrical discharges. A TLE was later identified, appearing in only two frames of the film. The annual December meetings of the American Geophysical Union have been reunions of the close-knit sprite community since 1994. That ELVES was discovered in the Shuttle Video by the Mesoscale Lightning Experiment (MLE) team at Marshall Space Flight Center, AL led by the Principal Investigator, Otha H."Skeet" Vaughan, Jr. ELVES is a whimsical acronym for Emissions of Light and Very Low Frequency Perturbations due to Electromagnetic Pulse Sources. Lightning strike. The first sprites were observed in Brazil, a major thunderstorm playground, using instrumented balloons and planes. Oct 28, 2020. ELVES were first recorded on another shuttle mission, this time recorded off French Guiana on October 7, 1990. Upper-atmospheric lightning. , Ichimoku Kink? The Sprite Watchers home page gives advice on how to look for them. A few photos give the further detail that the tops of these lights shade to blue. Hy? ) C-sprites exhibiting tendrils are sometimes called carrot sprites. The two main types of jets are blue jets and gigantic jets. Sprites have since been witnessed thousands of times. The most common TLE is the sprite—a flash of red light directly above large thunderstorms. The jet was located above a thunderstorm over an ocean, and lasted under a second. Blue starters were discovered on video from a night time research flight around thunderstorms and appear to be "an upward moving luminous phenomenon closely related to blue jets." TLE or Transient Luminous Event, that involve upper atmospheric lightning. The majority of these images, which include the first color imagery, are associated with a single thunderstorm. They last about a millisecond and are followed by sprites, which seem to grow right from their disks. These transient luminous events or TLEs are similar to lightning. Topics similar to or like Upper-atmospheric lightning. Their effects high in the atmosphere in … The Imager is an intensified CCD system operating in the visible wavelength region with a filter wheel to select from six positions with filters. In the 1920s, the Scottish physicist C.T.R. Lyons is still looking for new lights. MIME type Image/png. Thunderstorms fill the sky with lights above as well as beneath the clouds. your own Pins on Pinterest 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. Their color was a puzzle for some time, but is now believed to be a red hue. Upper-atmospheric lightning: | | ||| | Representation of upper-atmospheric lightning and elec... World Heritage Encyclopedia, the aggregation of the largest online encyclopedias available, and the most definitive collection ever assembled. Blue jets occur much less frequently than sprites. Other researchers take storm-jumper planes into the turbulent night skies to capture the elusive flashes. ELVES (Emission of Light and Very Low Frequency perturbations due to Electromagnetic Pulse Sources) often appear as a dim, flattened, expanding glow around 400 km (250 mi) in diameter that lasts for, typically, just one millisecond. When talking about lightning, appearances of different lightning which occur along with thunderstorms will emerge in the minds of the people and these lightning occur in the troposphere. Sprites are plentiful in the American Midwest, where great thunderstorms are common, but they are reported in many other places. 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.
