According to science, the blue sky is a result of the dispersion of light. However, it may come as a surprise that lighting also presents a diverse range of colors.
Before anything else, it is important to have a grasp of the scientific principles that govern lightning.
Definition of Lightning
According to definition, lightning is a prominent discharge of electricity from a cloud. This occurs when there is a notable difference in charge between a particular area of the cloud and another surface, typically the atmosphere, a structure, another part of the same cloud, or another cloud, in order to overcome air resistance.
As previously stated, Lightning comes in a diverse range of colors such as Red, Yellow, Green, Cyan, Blue, and Violet. While it is primarily white, it often displays a hint of another color along the edges.
In addition to white, the three most notable colors that can be observed are blue, yellow, and violet. The temperature of the lightning determines the color of the bolt. The colder the lightning, the further the color will be on the spectrum.
One of the most concerning and uncommon colors of lighting is green, which is a potential indicator of an approaching tornado. This phenomenon typically happens in the evening as the sun moves closer to the horizon. While the sky may take on a reddish hue during sunset, its predominant color is blue. When red light shines on a blue object, it can create the illusion of green. Additionally, if there is a thundercloud that reaches a height of 12 miles, green lighting may be observed.
Let’s delve deeper and gain a better understanding of what occurs when the sky turns green.
What is the significance of the green light in the sky?
The image of a green lightning bolt can be seen in this photograph, captured by the camera lens.
According to storm spotters, green lightning is a notable occurrence, however, it does not necessarily indicate the presence of a tornado. The formation of a green cloud is only possible if the cloud is exceptionally deep, which typically happens in thunderstorm clouds. These storms are known to produce destructive weather phenomena such as hail and tornadoes. The occurrence of green lightning is a signal that the cloud is significantly tall, and since thunderclouds are the tallest type of clouds, this green color serves as a warning that there is a possibility of large hail or a tornado approaching.
The eruption of the Chaiten volcano in Chile was a rare event that captured the attention of many, as it was the only known instance of green lightning being captured on camera. This unique occurrence was caused by the eruption spewing volcanic ash into the atmosphere, which is known to sometimes produce lightning bolts, also known as volcanic lightning. The photographer, Carlos Gutierrez, was able to capture this astonishing sight in a photograph.
However, how does that suggest a connection to a tornado?
Various Types of Lightning
It is intriguing to note that green lights are not the sole indicator of a natural disaster. Different colors of light can signify various situations.
The color of lightning can also vary depending on the atmospheric conditions within the clouds and air.
Upon discovering the various hues of light, I became curious as to which one holds the greatest strength.
White: the dominant color of lightning
The color white is considered to be the most perilous when it comes to lightning. It indicates a combination of low moisture levels and high levels of dust in the air. It is a well-known fact that being struck by lightning can have severe repercussions. Direct contact with lightning can lead to cardiac and respiratory arrest, memory loss, epilepsy, and severe burns on the entire body.
In my investigation of lightning, I also discovered that there exist uncommon forms of lightning. It may interest you to learn about the four most uncommon types of lightning.
1. Phenomenon of Ball Lightning
According to National Geographic, ball lightning is exactly what its name implies – not a mysterious phenomenon. Over the years, there have been numerous accounts of glowing orbs, approximately the size of a grapefruit, spinning steadily and hovering above the ground during thunderstorms. In some instances, the ball has been reported to pass through closed windows or even abruptly appear. However, it typically disappears after ten seconds.
2. Characters
Sprites are tiny beings that reside underground. These creatures resemble red jellyfish and can be seen gliding above thunderstorms. Initially appearing as orbs of light, they eventually descend in a stream-like manner. These phenomena are believed to be a result of lightning strikes occurring beneath storm clouds, leading to an accumulation of electrical charges above them.
3. Magical Beings of the Forest
Elves and sprites share many similarities. Both are known for their agility and weightlessness. These ethereal beings are often spotted soaring high in the sky during daytime. While sprites are known for their playful hoop dances, elves are often seen forming rings or halos. Despite their small appearance, elves can reach an impressive size of 185 miles (300 kilometers).
4. Black Lightning
Dark lightning, unlike typical lightning, releases minimal visible light. It consists of fast-moving electrons that disrupt air particles and release harmful gamma rays, whereas regular lightning is composed of slower electrons that conduct electricity between clouds or the ground.
Nature’s creativity knows no bounds!
Throughout our lives, we have been warned of the dangers of lightning and the need for caution. However, it was never mentioned that lightning could also possess such stunning beauty. Our blog thoroughly explores the various colors and rare forms of lightning. This has sparked my interest in other unusual phenomena of nature. As you continue reading, I am already delving into researching other fascinating events in nature.
