Graduate student Christopher Sterpka remembers the first time he saw ball lightning, as a 9- or 10-year-old staying at his grandparents'' house in West Hartford, Conn.
However, ball lightning is rarely observed and much less well understood. It is estimated that only one in a million lightning strikes produces the ball lightning phenomenon. Despite this, there are more than 10,000 written accounts of the bright, spherical lights in the sky, which linger for seconds longer than a true lightning bolt. ...
Ball lightning is a rare and mysterious form of atmospheric electrical phenomenon that appears as a floating, glowing sphere. Most report involve thunderstorms, but sometimes it appears in connection with other electrical events. Unlike the familiar streaks of lightning, ball lightning is a luminous, spherical or pear-shaped object.
Encyclopædia Britannica, Inc. Ball lightning, according to observers, manifests as a bright hissing orb of lightning ranging from 1 to 100 centimeters in diameter that appears during thunderstorms, often levitating above the ground and moving regardless of wind intensity or direction.Often colored red, orange, yellow, or blue, ball lightning has been described as sometimes entering …
Ball Lightning in beta wasn''t that good, but that has everything to do with the way the ability scales, compared to others.Like, take chain lightning, that ability starts off strong and scales fast with damage modifiers. But the thing with Ball Lightning, is that it scales with attack speed and really is there for the amount of lucky hit or ...
What is Ball Lightning? Ball lightning is a highly unusual and poorly understood atmospheric phenomenon characterized by the appearance of luminous, spherical objects during thunderstorms. These glowing balls of light typically range in size from golf balls to basketballs and can vary in color from red and orange to white or even blue.
In this book, well documented cases of ball lightning are described and used to unravel some aspects of this mysterious form of atmospheric electricity. Throughout the book, the author discusses the various facets of the problem in …
Ball lightning has been extensively reported, usually in association with thunderstorms, by chance observers who constitute perhaps five percent of the adult U.S. …
Reports of what ball lightning looks like vary widely, but most accounts share common characteristics. Witnesses often describe it as a bright, glowing sphere that is often colored red, orange, yellow, or blue.The size of the sphere can also vary, with some accounts describing it as smaller than a golf ball, while others report it as being larger than a beach ball.
Ball lightning 2,3,4,5 exhibits very diverse characteristics, such as close association with ordinary lightning, globate structure with steady glow for 1–5 seconds and...
The main characteristics of ball lightning are well established. They include its general appearance (shape, size range, brightness, etc.), its peculiar motion and, less …
Energilagring er lagring av produsert energi for bruk på et senere tidspunkt. I et energiforsyningssystem oppstår det et behov for å lagre energi når det ikke er sammenfall mellom produksjon og forbruk av energi. En enhet som lagrer energi blir …
Energilagring är avgörande för att vi ska kunna bygga en pålitlig och effektiv energiförsörjning. När en allt större andel av vår energianvändning utgörs av el, växer behovet av att kunna lagra energi och hämta ut den vid behov. I den här artikeln ska vi utforska olika typer av energilagringssystem och deras potential att forma ...
The text by Barry defined the difference between bead lightning (a string of luminous lightning segments) and ball lightning, and his work followed in a similar style to that of Singer''s.This is a very detailed book with thorough chapters on deduced ball lightning characteristics, photographs, and laboratory experiments.
A compilation of 17 observations of ball lightning showing the most energetic effects is presented along with estimates of their energy content. These observations were …
Energilagring är idag ett effektivt sätt att temporärt lagra överskottsenergi från till exempel vindkraft, industrier och kraftvärmeproduktion. Energilagring kan buffra och flytta överskottsenergi från sommar till vinter. Detta möjliggör en större andel förnybar energi i våra energisystem, vars elproduktion från sol- och vindkraftverk är mer ojämn och årstidsberoende.
1. 3 seconds of real-time video slowed down to show the ball lightning''s evolution in shape, color, and brightness and its associated spectrum.. One popular theory is that ball lightning is caused when lightning striking the ground vaporizes some of the silicate minerals in soil. Carbon in the soil strips the silicates of oxygen through chemical reactions, creating a gas …

A sphere of pulsating lightning appears in an unoccupied space of your choice within range and lasts for the duration. A creature that comes within 10 feet of the sphere for the first time on a turn must make a Dexterity saving throw, with disadvantage if it is wearing armor made of metal. The creature takes 1d8 lightning damage on a failed save, or half as much damage on a successful …
Research on ball lightning has languished up to now due to, in particular, the extreme difficulty of obtaining instrumented data on the phenomenon. But as we will describe below, the popularity of fixed and mobile video recording devices and systematic observations with the use of scientific instruments, in particular, in the gamma-ray range ...
Ball lightning, a rare aerial phenomenon in the form of a luminous sphere that is generally several centimetres in diameter. It usually occurs near the ground during thunderstorms, in close association with cloud-to-ground lightning. …
What is ball lightning? Scientists have been trying to figure that out for hundreds of years, and now it seems they may finally be close to solving one of Earth''s most intriguing natural mysteries.
Whether ball lightning will ever be captured reliably on camera remains to be seen, but Texas State''s Stephan hopes that by collecting anecdotes he can piece together the kinds of conditions ...
Ball Lightning vs. Lightning: What''s the Difference? Ball lightning and regular lightning are both electrical phenomena, but they differ in appearance and behavior. Lightning is a sudden, intense flash of light that occurs during thunderstorms, typically in the form of a jagged, branching bolt. Ball lightning, however, is a rare phenomenon ...
When Chen''s parents are incinerated before his eyes by a blast of ball lightning, he devotes his life to cracking the secret of mysterious natural phenomena. His search takes him to stormy mountaintops, an experimental military weapons lab, and an old Soviet science station. The more he learns, the more he comes to realize that ball lightning is just the tip of an entirely new …
Ball Lightning is very mana hungry, and as a result we have to pack the build with ways to restore our mana. The main way we do this is by generating crackling energy with Ball Lightning and passively picking it up which grants 12 mana per pickup. Luckily for us, the cracklings get generated at our feet so it happens passively.
The reason for the low emissive power in the optical range characteristic for the atmospheric ball lightning is explained by the absence of electron transitions in the outer proton …
In 1936, a man named Morris saw a red ball lightning the size of an orange enter a water barrel which contained 18 liters of water, which proceeded to boil. That would yield an energy density at about 6000 J/cm^3. In 1972, 30 people in a Hungarian factory saw a football sized ball lightning enter a water pit and boil about 120 liters away.
