What is invisible 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.
Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds. "Sheet lightning" describes a distant bolt that lights up an entire cloud base. Other visible bolts may appear as bead, ribbon, or rocket lightning.
In the most common type of cloud-to-ground lightning (CG), a channel of negative charge, called a stepped leader, will zigzag downward in roughly 50-yard segments in a forked pattern. This stepped leader is invisible to the human eye, and shoots to the ground in less time than it takes to blink.
Lightning is caused by the accumulation of charges in the cloy s. Some objects can be charged by rubbing with other objets. The electrical charge produced by rubbing is called static charge. There are two ]rinds of charges-positive charge and negative charge.
Lightning is a naturally occurring electrostatic discharge during which two electrically charged regions, both in the atmosphere or with one on the ground, temporarily neutralize themselves, causing the instantaneous release of an average of one gigajoule of energy.
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.
Lightning is a sudden electrostatic discharge that occurs typically during a thunderstorm. This discharge occurs between electrically charged regions of a cloud (called intra-cloud lightning or IC), between two clouds, or between a cloud and the ground.
Lightning can be explained in terms of charges produced due to rubbing. During a thunderstorm, the air currents move upwards and the water droplets move downwards. And this is caused due to the separation of charge due to this vigorous motion.
Cause of lightning
During thunderstorm, when a charged cloud passes over an uncharged cloud, uncharged cloud acquires opposite charge by induction and the two clouds attract. When they combine with each other, they produce a large amount of heat, light and sound also known as lightning.
Technically, there is no such thing as heat lightning! Those flashes of light are real lightning strikes from a thunderstorm. However, those thunderstorms can be quite far away, tens and sometimes even hundreds of miles away, which is why you don't hear the thunder.
Is Black lightning a real thing?
However, the weather phenomenon referred to as "dark lightning" occurs much less frequently. According to NASA, dark lighting is a mostly invisible burst of energy inside of thunderstorms that fills the sky with gamma rays. It is widely considered the most energetic radiation produced naturally on Earth.
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.
Lightning conductor is a metal rod placed on a building and connected with the ground below to protect the building from being damaged by lightning. Its purpose is to offer a low resistance path to lightening and allow it to pass to the ground without impacting the building.
Lightning happens when the negative charges (electrons) in the bottom of the cloud are attracted to the positive charges (protons) in the ground.
Lightning is one of nature's most spectacular shows, and it is caused by static electricity. An electric charge is produced when raindrops in clouds freeze into ice particles and crash together. This electric charge builds up and then discharges (releases) into the atmosphere as lightning.
Like regular lightning, red lightning is caused by a build-up of electrical charge in clouds, but in this case the excess charge is released to the ionosphere — around 50 miles (81 kilometers) up — rather than to the ground. Sprites are usually red in colour, and can range in shape between a jellyfish and a carrot.
The distinctive blue-white color of lightning is caused by light emitted as the electrons drop back to their original energy states. Seen from above, lightning storms also produce less well-known emissions of blue or red light above the clouds, known as jets and sprites.
In fact, lightning can heat the air it passes through to 50,000 degrees Fahrenheit (5 times hotter than the surface of the sun). When lightning strikes a tree, the heat vaporizes any water in its path possibly causing the tree to explode or a strip of bark to be blown off.

Whereas negative lightning produces 300 million volts and 30,000 amps, positive lightning can produce nearly a billion volts and 300,000 amps. It's rarer, but it's also more deadly.
What is another name for lightning?
A single streak of lightning can be called a lightning bolt or just a bolt. Since thunder and lightning typically go together, this is sometimes called a thunderbolt or even a thunderstroke. The bright light released is sometimes called a flash of lightning.
A category 1 storm has winds between 74 and 95 miles per hour. A category 5 hurricane has wind speeds of 157 miles per hour or higher. No storm is completely predictable. But meteorologists use tools to forecast weather patterns.
Storm: When the wind blows at a low speed in a gentle manner, it is called a breeze. But, when the wind blows violently at high speed, then it is called a storm. A storm is a low-pressure system.
A rotating column of high-speed winds that appears as a dark funnel-shaped cloud reaching from the sky to the ground is called a tornado. A tornado may form within a cyclone. A tornado forms due to the effect of low pressure in the eye of a cyclone.
The cold air has ice crystals. The warm air has water droplets. During the storm, the droplets and crystals bump together and move apart in the air. This rubbing makes static electrical charges in the clouds.
Lightning conductor does not allow the charge to accumulate on a building. It transfers all the charges to the earth, protecting the building from being struck by lightning.
Direct Strike
A person struck directly by lightning becomes a part of the main lightning discharge channel. Most often, direct strikes occur to victims who are in open areas. Direct strikes are not as common as the other ways people are struck by lightning, but they are potentially the most deadly.
No, it is not possible to have thunder without lightning. Thunder starts as a shockwave from the explosively expanding lightning channel when a large current causes rapid heating. However, it is possible that you might see lightning and not hear the thunder because it was too far away.
When lightning strikes, different particles will scatter this light and cause the strike to appear as blue, pink, purple, white or even a brown-ish tint.
ball lightning, also called globe lightning, a rare aerial phenomenon in the form of a luminous sphere that is generally several centimetres in diameter.
Is white lightning possible?
White lightning is a sign of low humidity or a little amount of moisture in the air. White is the color of lightning that most often ignites forest fires.
“Superbolts” are the most powerful lightning on Earth, with discharges so strong that they cannot be reproduced in the laboratory. The bolts also display geographic and seasonal attributes opposite that of regular lightning, adding to their mystery.

The radiation in these invisible blasts can carry a million times as much energy as the radiation in visible lightning, but that energy dissipates quickly in all directions rather than remaining in a lightning bolt. This is what scientists are calling dark lightning and it is invisible to the human eye.

Heat lightning, also referred to as silent lightning or summer lightning, is not a thing. The inaccurate term is often used for the faint flashes of lightning on the horizon or other clouds from distant thunderstorms that do not appear to have the accompanying sounds of thunder.
The term heat lightning is commonly used to describe lightning from a distant thunderstorm just too far away to see the actual cloud-to-ground flash or to hear the accompanying thunder.
Silent lightning, otherwise known as heat lightning, is when lightning occurs but is not followed by the expected roll of thunder. When lightning is silent it is likely that it comes from a distant thunderstorm that is too far away for people to hear any noise.
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.
Can lightning form diamonds?
Lightning storms turn methane into soot (carbon) which as it falls hardens into chunks of graphite and then diamond.
Sometimes lightning may be seen but there is no thunder heard. This is either because thunder is rarely heard more than 20 km away or because the atmospheric conditions lead to sound bending upwards and away from the surface.
If you see lightning but don't hear thunder, it is because the thunder is too far away. Sometimes, people refer to this as heat lightning because it most often occurs in the summer , but it is no different from regular lighting.
Dry lightning, which can spark fires, is common in Northern California, study shows - The Washington Post.

As for being struck by heat lightning, the odds are very low so long as it remains too far away to see the lightning path and hear thunder. However, if the storm is moving in your direction and continues to produce lightning, it is of course possible to be struck.
Because of the heat they generate, flashes with continuing current are sometimes referred to as hot lightning while flashes containing only return strokes are referred to as "cold lightning."
An observer may see nearby lightning, but the sound from the discharge is refracted over their head by a change in the temperature, and therefore the density, of the air around him. As a result, the lightning discharge seems to be silent.
Dry thunderstorm refers to thunder and lightning that occur without bringing rain to the ground. In fact, the thunder-bearing clouds do produce rain but the rain droplets have evaporated in the air before reaching the ground.
