What is fork lightning?

Cloud-to-Ground (CG) Lightning

In CG lightning, a channel of negative charge, called a stepped leader, will zigzag downward in a 'forked' pattern - hence it is sometimes called forked lightning. This stepped leader is invisible to the human eye, and travels to the ground in a millisecond.

What does it mean to fork lightning?

Forked lightning is lightning that divides into two or more parts near the ground.

What is the difference between fork lightning and sheet lightning?

People describe lightning as 'sheet' or 'forked', but the only difference between the two is where they take place. Forked lightning is the shape we see when the bolt hits the ground, and sheet lightning is lightning that occurs within a cloud, lighting it up sheet-style (so we only see the flashes, not the bolts).

What are the 3 types of lightning?

There are three common types of lightning: cloud to ground, cloud to cloud and cloud to air. Cloud to ground lightning is the most dangerous. The ground is mainly consisted of positively charged particles while the bottom of violent storm clouds have negative charged particles.

What is the rarest type of 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.

7 Incredible lightning types | Amazing Weather

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.

Does dark lightning exist?

Dark lightning is the most energetic radiation produced naturally on Earth, but was unknown before 1991. While scientists now know that dark lightning naturally occurs in thunderstorms, they do not know how frequently these flashes take place or whether visible lightning always accompanies them.

What is lightning without thunder called?

Heat lightning, also known as silent lightning, summer lightning, or dry lightning (not to be confused with dry thunderstorms, which are also often called dry lightning), is a misnomer used for the faint flashes of lightning on the horizon or other clouds from distant thunderstorms that do not appear to have ...

What is a jet lightning?

Jets. 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.

What is red lightning?

Sprites, also known as red lightning, are electrical discharges that appear as bursts of red light above clouds during thunderstorms.

Does fork lightning hit the ground?

Lightning can strike the ground, the air, or inside clouds, but there are roughly 5 to 10 times more cloud flashes than there are cloud-to-ground flashes. In CG lightning, a channel of negative charge, called a stepped leader, will zigzag downward in a 'forked' pattern - hence it is sometimes called forked lightning.

What is Spider lightning?

Spider lightning refers to long, horizontally traveling flashes often seen on the underside of stratiform clouds. Spider lightning is often linked to +CG flashes.

What is the 30 30 rule for lightning?

Don't forget the 30-30 rule. After you see lightning, start counting to 30. If you hear thunder before you reach 30, go indoors. Suspend activities for at least 30 minutes after the last clap of thunder.

What does forked no lightning mean?

Because Their Words Had Forked No Lightning

In his second stanza Thomas describes the wise men whose words forked no lighting. The meaning of this is that their words weren't able to leave their desired mark on the world.

How is heat lightning created?

In reality, heat lightning is simply a lightning flash produced by a distant thunderstorm. Hills, trees or even the curvature of the earth prevent the observer from seeing the actual lightning bolt, which is why it appears to be "out of thin air."

How many coulombs are in a lightning bolt?

An average bolt of negative lightning carries an electric current of 30,000 amperes (30 kA), and transfers 15 C (coulombs) of electric charge and 1 gigajoule of energy. Large bolts of positive lightning can carry up to 120 kA and 350 C.

What is blue lightning?

A "Bolt from the Blue" is a cloud to ground lightning flash which typically comes out of the back side of the thunderstorm cloud, travels a relatively large distance in clear air away from the storm cloud, and then angles down and strikes the ground.

What is space lightning?

A streak of purple "lightning" sprawls across the cosmos in a gorgeous new image from NASA. Light and energy twist and turn in an explosive relationship between a stellar corpse known as a white dwarf and a variable red giant star called R Aquarii (R Aqr) orbiting each other out in space.

What are elves lightning?

Elves are huge red halos that occur high in the atmosphere at around 100 km above active thunderstorms. They can be up to 400 km in diameter and last only about a millisecond. Surprisingly, the existence of elves was predicted before one was actually observed.

Why is the lightning green?

Green lightning does indicate that the cloud is extremely tall, and because thunderclouds are the tallest clouds, green is a warning sign that large hail or a tornado is on the way. Green lightning has only been photographed once when the Chaiten volcano in Chile erupted. Spewing an ash cloud into the atmosphere.

Does lightning make noise?

Thunder is the sound caused by a nearby flash of lightning and can be heard for a distance of only about 10 miles from the lightning strike. The sound of thunder should serve as a warning to anyone outside that they are within striking distance of the storm and need to get to a safe place immediately!

Is lightning hotter than the sun?

In fact, lightning can heat the air it passes through to 50,000 degrees Fahrenheit (5 times hotter than the surface of the sun).

Is there lightning in the ocean?

Lightning doesn't strike the ocean as much as land, but when it does,it spreads out over the water, which acts as a conductor.

What is the speed of lightning?

1. The speed of lightning. While the flashes we see as a result of a lightning strike travel at the speed of light (670,000,000 mph) an actual lightning strike travels at a comparatively gentle 270,000 mph.

Can lightning invisible?

But scientists recently discovered something mind-bending about lightning: Sometimes its flashes are invisible, just sudden pulses of unexpectedly powerful radiation. It's what Joseph Dwyer, a lightning researcher at the Florida Institute of Technology, has termed dark lightning.
