What causes trigger lightning?
Upward triggered lightning usually occurs in response to a natural lightning flash, but on rare occasions can be “self-triggered”—usually in winter storms with strong winds. Lightning can also be triggered by aircraft flying through strong electric fields. If the plane is below the cloud, then a CG flash could result.
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.
It is hypothesised that triggered lightning strikes may occur when a helicopter flies: into a positively charged base of a Cb cloud. under the positively charged anvil of a Cb cloud. from a positively charged region of cloud to a negatively charged one.
It helps you accurately time your lightning shots.
A lightning trigger does not only detect a lightning event and activate your camera to take a photo. If it is a smart trigger, it can offer more than that. In fact, a smart trigger can help you time your shots.
Lightning is visible as a flash of light because of both incandescence (due to its high temperature it glows blue-white) and luminescence (excitation of nitrogen gas in the atmosphere). Nitrogen, the dominant gas in the atmosphere, is excited by this strong flow of energy, its electrons moving to higher energy states.
What is lightning? Lightning is a giant spark of electricity in the atmosphere between clouds, the air, or the ground. In the early stages of development, air acts as an insulator between the positive and negative charges in the cloud and between the cloud and the ground.
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.
There is an accumulation of positive charges near the ground also. When the magnitude of the accumulated charges becomes large, the air cannot resist their flow. As a result, negative and positive charges meet producing a streak of bright light and sound, called lightning.
Myth: Structures with metal, or metal on the body (jewelry, cell phones,Mp3 players, watches, etc), attract lightning. Fact: Height, pointy shape, and isolation are the dominant factors controlling where a lightning bolt will strike. The presence of metal makes absolutely no difference on where lightning strikes.
Lightning can be artificially generated on a small scale, either by electrostatic machines, impulse generators or even the simple scuffing of one's feet on carpeted floor on a winter day.
Can lightning be trapped?
A high power laser could be used to form an ionized column of gas, which would act as an atmospheric conduit for electrical discharges of lightning, which would direct the lightning to a ground station for harvesting.
Currently, the best camera trigger in the market is the MIOPS Smart Trigger. The MIOPS Smart Trigger is a combination of a versatile camera and flash trigger in a single unit. The unique thing about this trigger is that it comes in many advanced triggering modes such as lightning, sound, laser and time-lapse.
According to a doctor, the injuries could have been much worse had it not been for the fact that they were walking hand in hand. "These two were lucky they that they were holding hands. It helped to diffuse the electrical current that ran through their bodies," Dr.
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.
Created when positive and negative charges in the atmosphere equalize, lightning is neither solid, liquid, nor gas; it's the fourth state of matter, known as plasma.
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.

Areas of heavy rain that are a bit farther out from the tornado sometimes spiral inward toward the area of rotation, like the spiral bands that extend outward from the eye of a hurricane. Some tornadoes feature a single main funnel cloud. Others have multiple small funnels that rotate around each other.
A tornado is violent, twisted funnelof high speed wind. A cyclone consists of a low pressure areaIt is formed when a funnel like columnwith high pressure all around.

What is a lightning conductor Class 8?
A lightning conductor is used to save big buildings from the damage by lightning flashes. A lightning conductor consists of a number of pointed conductors fixed to the top of a building and connected to a thick copper wire. This wire runs down the side of the building and ends on a metal plate buried in the ground.
One major study from 2014 estimated that, if warming continues at its current pace, the number of lightning strikes in the U.S. could increase by as much as 50 percent by the end of the century, with each additional 1 degree Celsius of warming generating about 12 percent more strikes.
Lake Maracaibo in Venezuela is the place on Earth that receives the most lightning strikes. Massive thunderstorms occur on 140-160 nights per year with an average of 28 lightning strikes per minute lasting up to 10 hours at a time. That's as many as 40,000 lightning strikes in one night!
Because lightning tends to hit tall objects, trees are likely targets. They're especially prone to lightning strikes because electricity seeks the path of least resistance, and the sap and moisture inside a tree make it a better conductor than the surrounding air.
The heat produced when lightning moves over the skin can produce burns, but the current moving through the body is of greatest concern. While the ability to survive any lightning strike is related to immediate medical attention, the amount of current moving through the body is also a factor.
Although the vast majority of lightning strike victims survive, the effects can be serious and long-lasting. Survivors have experienced debilitating injuries, burns and ongoing disability, including symptoms like seizures and memory loss.
Of every 10 people struck, nine will survive. But they could suffer a variety of short- and long-term effects: cardiac arrest, confusion, seizures, dizziness, muscle aches, deafness, headaches, memory deficits, distractibility, personality changes and chronic pain, among others.
While no place is 100% safe from lightning, some places are much safer than others. The safest location during a thunderstorm is inside a large enclosed structure with plumbing and electrical wiring. These include shopping centers, schools, office buildings, and private residences.
You may also feel a physical tingling sensation throughout your body, especially in your extremities. This is often the gut feeling that people get when they "sense" that something is impending. If your hair is standing up, you may have only a few seconds to protect yourself from lightning.
Shockwave Damage to Your Home
A direct hit from a lightning bolt is so powerful that it can split stone, brick, cinderblock, and concrete with ease. If lightning strikes your home, the sheer force of the bolt can wreak havoc on your chimney, causing cracks and fractures or possibly flying shrapnel.
What causes lightning to spark?
The ground's positive charge concentrates around anything that sticks up - trees, lightning conductors, even people! The positive charge from the ground connects with the negative charge from the clouds and a spark of lightning strikes.
But wildfires can also spark lightning—a phenomenon that has puzzled scientists for decades. Now, researchers have revealed a key cause of this phenomenon: air pollution. Dirtier air means more lightning above wildfires—and more rain, too.
When You See Lightning, Count The Time Until You Hear Thunder. If That Is 30 Seconds Or Less, The Thunderstorm Is Close Enough To Be Dangerous – Seek Shelter (if you can't see the lightning, just hearing the thunder is a good back-up rule). Wait 30 Minutes Or More After The Lightning Flash Before Leaving Shelter.
Negative charges gather near the base of the cloud, while positive charges build in the top of the cloud. This allows electric fields to form and grow between the cloud and the ground and within the cloud itself - all necessary conditions for lightning to occur.
Thunder is a direct result of lightning. 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.
