Why is sprite lightning red?

Sprites or red sprites are large-scale electrical discharges that occur high above thunderstorm clouds, or cumulonimbus, giving rise to a quite varied range of visual shapes flickering in the night sky. They are usually triggered by the discharges of positive lightning between an underlying thundercloud and the ground.

Why red sprite is red?

Red sprites are thought to be caused by a rare but intense form of lightning called positive lightning. Whereas most cloud-to-ground lightning has a negative electric charge, positive lightning has a positive charge.

How rare is a red sprite?

Red sprites occur at altitudes of about 50 miles into the atmosphere and account for only 5 percent of all lightning phenomena. In fact, red sprites were only first photographed in 1989, and recordings like this one captured in a video by photographer Scott McPartland are extremely rare.

What color are lightning sprites?

Sprites are colored reddish-orange in their upper regions, with bluish hanging tendrils below, and can be preceded by a reddish halo.

What is a red sprite in weather?

Red sprites are large but weak luminous flashes that appear directly above an active thunderstorm system and are coincident with powerful positive cloud-to-ground lightning strokes.

What is the rarest color of lightning?

Green lightning is a rare phenomenon that can be seen during a thunderstorm. Someone who has seen green lightning is extremely lucky as green lightning strikes are rarely seen. It is so rare that the only photograph of a green lightning strike is one from when the Chaiten volcano in Chile erupted.

Is red lightning hotter than blue?

The color spectrum in this case start with infared which is red and the coolest up to ultraviolet which appears violet and is the hottest. Lightning also can take on a range of colors, depending on conditions in the clouds and in the air. Typically, blue lightning within a cloud indicates the presence of hail.

Why is there red lightning?

A red lightning is a form of electrical discharge in the upper atmosphere associated with thunderstorms. A wide electric field that gets generated by several lightning strokes ionizes the air high on top of the cloud. This then emits that light you can see in photos.

Is red lightning real?

Red lightning doesn't exist in the literal sense, according to the National Weather Service. The closest known phenomena is something called a red sprite, which occurs high in the atmosphere “directly above an active thunderstorm,” NOAA says.

How hot is red lightning?

It can reach temperatures approaching 30,000 K (55,000 °F). This is five times hotter than the surface of our sun!

Is blue lightning real?

When an unexpected event happens people describe it as a “bolt from the blue”. The phrase is actually based on real weather phenomena where a lightning bolt will strike an area with no overhead clouds. While bolts from the blue don't originate from blue sky, they occur infrequently, are unexpected, and can be deadly.

What is a jellyfish sprite?

Sometimes during a thunderstorm, you can glimpse tentacles of jellyfish-shaped lightning drooping down from space. This phenomenon is called a red sprite — it's a type of electrical discharge that happens up to 50 miles into the atmosphere.

Can lightning exist space?

Lightning as we know it in air cannot happen in vacuum because lightening depends crucially on the generation of positive ions and negative electrons by ionization of molecules of the air in high electric fields (and eventually high temperatures) and the ensuing impact ionization typical for a gas discharge.

Are sprites real?

If you're looking for sprites or elves dancing in the forest after dark, you might be disappointed—but in a way, they do exist. What are known as “sprites” and “elves” are actually Transient Luminous Events (TLEs) that emerge from the upper atmosphere when thunderstorms are brewing and lightning strikes.

Who discovered red sprites?

A team of scientists headed by Walter Lyons at the Massachusetts Institute of Technology studied readings from a national system of lightning ground strike detectors and discovered that red sprites correlate with positively charged ground strikes, which make up about 10 percent of lightning and are many times more ...

What are lightning 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 thunderstorms.

What is the rarest lightning?

ball lightning, also called globe 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.

Is there purple lightning?

Purple or lilac-tinted lightning bolt is often caused by high atmospheric humidity; which means the thunderstorm is accompanied by high-precipitation. Yellow lightning is uncommon; however, they tend to be cooler than the blue, lilac and white. They're caused to due to a high concentration of dust in the air.

Is blue lightning rare?

These colorful flashes are called blue jets and they can stretch 30 miles into the stratosphere. Blue jets can only be seen from the ground under rare circumstances because they're brief and are typically obscured by clouds.

Is Pink lightning real?

In snowstorms, where it is somewhat rare, pink and green are often described as colors of lightning. Haze, dust, moisture, raindrops and any other particles in the atmosphere will affect the color by absorbing or diffracting a portion of the white light of lightning.

How hot is white lightning?

This flow of electrons through the lightning bolt creates a very hot plasma, as hot as 50,000 degrees, that emits a spectrum of electromagnetic energy. Some of this radiation is in the form of radio waves and gamma rays.

How hot is violet lightning?

How Hot Is Purple Lightning? Purple lightning is often seen during thunderstorms and it's one of the more moderate forms of lightning with temperatures reaching up to 55,000 degrees Fahrenheit!

Is there Black lightning?

Scientists have just begun to understand a strange phenomenon known simply as "dark lightning". Different from regular lightning, dark lightning is a release of high-energy gamma radiation—sources include supernovae and supermassive black holes—that is completely invisible to the human eye.

Is purple lightning rare?

The rare purple lightning strike occurs far higher in the atmosphere than normal lightning – and has only rarely been caught on film. The flash of 'ionospheric lightning' stands out against the deep blue of a night sky behind, while the raging storm lights up the clouds below.

What is dark lightning?

Dark lightning is a burst of gamma rays produced during thunderstorms by extremely fast moving electrons colliding with air molecules. Researchers refer to such a burst as a terrestrial gamma ray flash.
