The three main kinds of lightning are distinguished by where they occur: either inside a single thundercloud , between two different clouds, or between a cloud and the ground.

Many other observational variants are recognized, including " heat lightning ", which can be seen from a great distance but not heard; dry lightning , which can cause forest fires ; and ball lightning , which is rarely observed scientifically.

Humans have deified lightning for millennia. Idiomatic expressions derived from lightning, such as the English expression "bolt from the blue", are common across languages.

The details of the charging process are still being studied by scientists, but there is general agreement on some of the basic concepts of thunderstorm electrification.

In that area, the combination of temperature and rapid upward air movement produces a mixture of super-cooled cloud droplets small water droplets below freezing , small ice crystals, and graupel soft hail.

The updraft carries the super-cooled cloud droplets and very small ice crystals upward. At the same time, the graupel, which is considerably larger and denser, tends to fall or be suspended in the rising air.

The differences in the movement of the precipitation cause collisions to occur. When the rising ice crystals collide with graupel, the ice crystals become positively charged and the graupel becomes negatively charged; see Figure 2.

The updraft carries the positively charged ice crystals upward toward the top of the storm cloud. The larger and denser graupel is either suspended in the middle of the thunderstorm cloud or falls toward the lower part of the storm.

The result is that the upper part of the thunderstorm cloud becomes positively charged while the middle to lower part of the thunderstorm cloud becomes negatively charged.

The upward motions within the storm and winds at higher levels in the atmosphere tend to cause the small ice crystals and positive charge in the upper part of the thunderstorm cloud to spread out horizontally some distance from the thunderstorm cloud base.

This part of the thunderstorm cloud is called the anvil. While this is the main charging process for the thunderstorm cloud, some of these charges can be redistributed by air movements within the storm updrafts and downdrafts.

In addition, there is a small but important positive charge buildup near the bottom of the thunderstorm cloud due to the precipitation and warmer temperatures.

The actual discharge is the final stage of a very complex process. The science of lightning is called fulminology , and the fear of lightning is called astraphobia.

Many factors affect the frequency, distribution, strength and physical properties of a typical lightning flash in a particular region of the world.

These factors include ground elevation, latitude , prevailing wind currents, relative humidity , and proximity to warm and cold bodies of water.

To a certain degree, the proportions of intra-cloud, cloud-to-cloud, and cloud-to-ground lightning may also vary by season in middle latitudes.

Because human beings are terrestrial and most of their possessions are on the Earth where lightning can damage or destroy them, CG lightning is the most studied and best understood of the three types, even though IC and CC are more common types of lightning.

Lightning's relative unpredictability limits a complete explanation of how or why it occurs, even after hundreds of years of scientific investigation.

This occurs from both the mixture of warmer and colder air masses , as well as differences in moisture concentrations, and it generally happens at the boundaries between them.

The flow of warm ocean currents past drier land masses, such as the Gulf Stream , partially explains the elevated frequency of lightning in the Southeast United States.

Because large bodies of water lack the topographic variation that would result in atmospheric mixing, lightning is notably less frequent over the world's oceans than over land.

The North and South Poles are limited in their coverage of thunderstorms and therefore result in areas with the least amount of lightning.

Since the base of a thunderstorm is usually negatively charged, this is where most CG lightning originates. This region is typically at the elevation where freezing occurs within the cloud.

Freezing, combined with collisions between ice and water, appears to be a critical part of the initial charge development and separation process.

During wind-driven collisions, ice crystals tend to develop a positive charge, while a heavier, slushy mixture of ice and water called graupel develops a negative charge.

Updrafts within a storm cloud separate the lighter ice crystals from the heavier graupel, causing the top region of the cloud to accumulate a positive space charge while the lower level accumulates a negative space charge.

Because the concentrated charge within the cloud must exceed the insulating properties of air, and this increases proportionally to the distance between the cloud and the ground, the proportion of CG strikes versus cloud-to-cloud CC or in-cloud IC discharges becomes greater when the cloud is closer to the ground.

In order for an electrostatic discharge to occur, two preconditions are necessary: firstly, a sufficiently high potential difference between two regions of space must exist, and secondly, a high-resistance medium must obstruct the free, unimpeded equalization of the opposite charges.

The atmosphere provides the electrical insulation, or barrier, that prevents free equalization between charged regions of opposite polarity.

It is well understood that during a thunderstorm there is charge separation and aggregation in certain regions of the cloud; however, the exact processes by which this occurs are not fully understood.

As a thundercloud moves over the surface of the Earth, an equal electric charge , but of opposite polarity, is induced on the Earth's surface underneath the cloud.

This is known as an image charge. The induced positive surface charge, when measured against a fixed point, will be small as the thundercloud approaches, increasing as the center of the storm arrives and dropping as the thundercloud passes.

The referential value of the induced surface charge could be roughly represented as a bell curve. The oppositely charged regions create an electric field within the air between them.

This electric field varies in relation to the strength of the surface charge on the base of the thundercloud — the greater the accumulated charge, the higher the electrical field.

The best studied and understood form of lightning is from cloud to ground CG. Although more common, intra-cloud IC and cloud-to-cloud CC flashes are very difficult to study given there are no "physical" points to monitor inside the clouds.

Also, given the very low probability of lightning will strike the same point repeatedly and consistently, scientific inquiry is difficult even in the areas of high CG frequency.

In a process not well understood, a bidirectional channel of ionized air, called a " leader ", is initiated between oppositely-charged regions in a thundercloud.

Leaders are electrically conductive channels of ionized gas that propagate through, or are otherwise attracted to, regions with a charge opposite of that of the leader tip.

The negative end of the bidirectional leader fills a positive charge region, also called a well, inside the cloud while the positive end fills a negative charge well.

Leaders often split, forming branches in a tree-like pattern. The resulting jerky movement of the leaders can be readily observed in slow-motion videos of lightning flashes.

It is possible for one end of the leader to fill the oppositely-charged well entirely while the other end is still active. When this happens, the leader end which filled the well may propagate outside of the thundercloud and result in either a cloud-to-air flash or a cloud-to-ground flash.

In a typical cloud-to-ground flash, a bidirectional leader initiates between the main negative and lower positive charge regions in a thundercloud.

The weaker positive charge region is filled quickly by the negative leader which then propagates toward the inductively-charged ground.

The positively and negatively charged leaders proceed in opposite directions, positive upwards within the cloud and negative towards the earth.

Both ionic channels proceed, in their respective directions, in a number of successive spurts. Each leader "pools" ions at the leading tips, shooting out one or more new leaders, momentarily pooling again to concentrate charged ions, then shooting out another leader.

The negative leader continues to propagate and split as it heads downward, often speeding up as it gets closer to the Earth's surface.

The electric current needed to establish the channel, measured in the tens or hundreds of amperes , is dwarfed by subsequent currents during the actual discharge.

Initiation of the lightning leaders is not well understood. The electric field strength within the thundercloud is not typically large enough to initiate this process by itself.

One theory postulates that showers of relativistic electrons are created by cosmic rays and are then accelerated to higher velocities via a process called runaway breakdown.

As these relativistic electrons collide and ionize neutral air molecules, they initiate leader formation. Another theory involves locally enhanced electric fields being formed near elongated water droplets or ice crystals.

When a stepped leader approaches the ground, the presence of opposite charges on the ground enhances the strength of the electric field. The electric field is strongest on grounded objects whose tops are closest to the base of the thundercloud, such as trees and tall buildings.

If the electric field is strong enough, a positively charged ionic channel, called a positive or upward streamer , can develop from these points.

This was first theorized by Heinz Kasemir. As negatively charged leaders approach, increasing the localized electric field strength, grounded objects already experiencing corona discharge exceed a threshold and form upward streamers.

Once a downward leader connects to an available upward leader, a process referred to as attachment, a low-resistance path is formed and discharge may occur.

Photographs have been taken in which unattached streamers are clearly visible. The unattached downward leaders are also visible in branched lightning, none of which are connected to the earth, although it may appear they are.

High-speed videos can show the attachment process in progress. Once a conductive channel bridges the air gap between the negative charge excess in the cloud and the positive surface charge excess below, there is a large drop in resistance across the lightning channel.

Electrons accelerate rapidly as a result in a zone beginning at the point of attachment, which expands across the entire leader network at up to one third of the speed of light.

A large electric charge flows along the plasma channel, from the cloud to the ground, neutralising the positive ground charge as electrons flow away from the strike point to the surrounding area.

This huge surge of current creates large radial voltage differences along the surface of the ground. Called step potentials, [ citation needed ] they are responsible for more injuries and deaths in groups of people or of other animals than the strike itself.

The electric current of the return stroke averages 30 kiloamperes for a typical negative CG flash, often referred to as "negative CG" lightning.

In some cases, a ground to cloud GC lightning flash may originate from a positively charged region on the ground below a storm.

These discharges normally originate from the tops of very tall structures, such as communications antennas. The massive flow of electric current occurring during the return stroke combined with the rate at which it occurs measured in microseconds rapidly superheats the completed leader channel, forming a highly electrically conductive plasma channel.

The core temperature of the plasma during the return stroke may exceed 50, K, causing it to radiate with a brilliant, blue-white color.

Once the electric current stops flowing, the channel cools and dissipates over tens or hundreds of milliseconds, often disappearing as fragmented patches of glowing gas.

The nearly instantaneous heating during the return stroke causes the air to expand explosively, producing a powerful shock wave which is heard as thunder.

High-speed videos examined frame-by-frame show that most negative CG lightning flashes are made up of 3 or 4 individual strokes, though there may be as many as Each re-strike is separated by a relatively large amount of time, typically 40 to 50 milliseconds, as other charged regions in the cloud are discharged in subsequent strokes.

Re-strikes often cause a noticeable " strobe light " effect. To understand why multiple return strokes utilize the same lightning channel, one needs to understand the behavior of positive leaders, which a typical ground flash effectively becomes following the negative leader's connection with the ground.

Positive leaders decay more rapidly than negative leaders do. For reasons not well understood, bidirectional leaders tend to initiate on the tips of the decayed positive leaders in which the negative end attempts to re-ionize the leader network.

These leaders, also called recoil leaders , usually decay shortly after their formation. When they do manage to make contact with a conductive portion of the main leader network, a return stroke-like process occurs and a dart leader travels across all or a portion of the length of the original leader.

The dart leaders making connections with the ground are what cause a majority of subsequent return strokes. Each successive stroke is preceded by intermediate dart leader strokes that have a faster rise time but lower amplitude than the initial return stroke.

Each subsequent stroke usually re-uses the discharge channel taken by the previous one, but the channel may be offset from its previous position as wind displaces the hot channel.

Since recoil and dart leader processes do not occur on negative leaders, subsequent return strokes very seldom utilize the same channel on positive ground flashes which are explained later in the article.

The electric current within a typical negative CG lightning discharge rises very quickly to its peak value in 1—10 microseconds, then decays more slowly over 50— microseconds.

The transient nature of the current within a lightning flash results in several phenomena that need to be addressed in the effective protection of ground-based structures.

Rapidly changing currents tend to travel on the surface of a conductor, in what is called the skin effect , unlike direct currents, which "flow-through" the entire conductor like water through a hose.

Hence, conductors used in the protection of facilities tend to be multi-stranded, with small wires woven together. This increases the total bundle surface area in inverse proportion to the individual strand radius, for a fixed total cross-sectional area.

The rapidly changing currents also create electromagnetic pulses EMPs that radiate outward from the ionic channel.

This is a characteristic of all electrical discharges. The radiated pulses rapidly weaken as their distance from the origin increases. However, if they pass over conductive elements such as power lines, communication lines, or metallic pipes, they may induce a current which travels outward to its termination.

The surge current is inversely related to the Surge impedance Devices known as surge protectors SPD or transient voltage surge suppressors TVSS attached in parallel with these lines can detect the lightning flash's transient irregular current, and, through alteration of its physical properties, route the spike to an attached earthing ground , thereby protecting the equipment from damage.

Three primary types of lightning are defined by the "starting" and "ending" points of a flash channel. There are variations of each type, such as "positive" versus "negative" CG flashes, that have different physical characteristics common to each which can be measured.

Different common names used to describe a particular lightning event may be attributed to the same or to different events. Cloud-to-ground CG lightning is a lightning discharge between a thundercloud and the ground.

It is initiated by a stepped leader moving down from the cloud, which is met by a streamer moving up from the ground. CG is the least common, but best understood of all types of lightning.

It is easier to study scientifically because it terminates on a physical object, namely the Earth, and lends itself to being measured by instruments on the ground.

Of the three primary types of lightning, it poses the greatest threat to life and property since it terminates or "strikes" the Earth.
