Elves 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. They occur in the ionosphere 100 km (62 mi) above the ground over … See more Upper-atmospheric lightning and 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 … See more In the 1920s, the Scottish physicist C.T.R. Wilson predicted that electrical breakdown should occur in the atmosphere high above large thunderstorms. In ensuing decades, high altitude electrical discharges were reported by aircraft pilots and discounted by See more 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 travels upwards. In contrast, other types … See more • Homepage of the Eurosprite campaign, itself part of the CAL (Coupled Atmospheric Layers) research group • March 2, 1999, University of Houston: UH Physicists Pursue Lightning-Like Mysteries See more There are several types of TLEs, the most common being sprites. Sprites are flashes of bright red light that occur above storm systems. C-sprites (short for “columniform sprites”) is the name given to vertical columns of red light. C-sprites exhibiting tendrils are … See more Sprites are large-scale electrical discharges which occur high above a thunderstorm cloud, or cumulonimbus, giving rise to a quite varied range of visual shapes. They are … See more • Weather portal • Spaceflight portal • Aurora • Heat lightning • Schumann resonances • Sprite (lightning) See more WebFrom their original design as elderly gnomes [1] with large noses, ears and hats, Snap, Crackle and Pop were reimagined with younger and more proportional features in 1949. Some time after 1955, their gnome-like oversized ears became more proportional yet pointed, as seen in common portrayals of elves.

WebMay 21, 2024 · The wavelength at ELF frequencies exceeds 10,000 km. A radar using that large a wavelength will not be able to locate anything very precisely. In addition, radiating and receiving radio signals efficiently requires an antenna size of a significant fraction of a wavelength; probably too big to fit on a submrarine.
