The fascinating realm of red lightning will astounds you! Fifteen amazing forms of red electrical discharges that brilliantly illuminate the sky are investigated in this paper. From uncommon sprites to elusive jets, every phenomena provides a different window through nature’s might. Discover the science underlying these vibrant displays and find out why both storm chasers and experts find them to still be fascinating. You have seen what number of these scarlet spectacles?
1. Red Sprites: Dancing Jellyfish in the Sky
Often characterised as like enormous jellyfish hovering in the high atmosphere, red sprites are among the most mysterious kinds of red lightning. Usually at heights between 50 and 90 km, these transient flashes of crimson light happen well above thunderstorms. Red sprites soar upward from the top of thunderclouds towards the edge of space, unlike ordinary lightning, which runs from cloud to earth.
Red sprites have first been seen on video in 1989 and have since attracted close scientific attention. With the naked eye, they are difficult to see since they happen in clusters and last barely a fraction of a second. Their unusual red hue results from the interaction of electrical discharges with nitrogen molecules in the rarefied air of the top atmosphere.
Specialised high-speed cameras are used by storm chasers and atmospheric researchers to record these elusive events. Although red sprites are now somewhat common, happening thousands of times daily worldwide, most people hardly ever see them because of their short lifetime and high altitude. Have you ever had the good fortune to see these ethereal crimson dancers in the nighttime heavens?
2. Blue Jets: The Sapphire Cousins of Red Lightning
Although blue jets are not red itself, they are strongly associated with red lightning events and frequently coexist with them. Rising from the summits of thunderclouds, these little, cone-shaped bursts of blue light reach stratosphere heights of up to 50 km. Given only a few tenths of a second, blue jets are even more elusive than red sprites.
Excitation of neutral and ionised molecular nitrogen produces blue jets’ azure colour. Blue jets are hypothesised to be started by the electrical breakdown between the top positive charge zone and the negative screening layer above the cloud, unlike red sprites which are triggered by positive cloud-to- ground lightning strikes.
Blue jets, according to scientists, might be very important in the global electrical circuit since they serve to balance the charge distribution between the ionosphere and the ground. Though they are rather important, blue jets remain one of the least known types of upper atmospheric lightning; many issues regarding their origin and consequences are unresolved.
3. ELVES: Expanding Rings of Red Light
Another interesting kind of red lightning phenomena is ELVES, short for Emission of Light and Very Low Frequency Perturbations owing to Electromagnetic Pulse Sources. About 100 kilometres above the ground of Earth, at the base of the ionosphere, these fast growing rings of red light arise.
Strong lightning strikes produce the electromagnetic pulse that causes ELVES. Red light is emitted in the lower ionosphere by this pulse producing a transient heating effect. One of the biggest transient luminous occurrences in the atmosphere, the ring-shaped discharge can spread to a diameter of up to 400 kilometres in less than a millisecond.
ELVES are quite difficult to see from the ground despite their great mass because of their high altitude and very brief lifetime. First seen in 1992 on low-light video cameras aboard the Space Shuttle, they With an estimated 35 incidents per minute worldwide, satellite observations since then have shown that ELVES occur far more frequently than formerly believed.
