Upside-down lightning strikes exist and pose a great threat to wind turbines!
Upward lightning strikes initiate on the ground and head skyward. These discharges, which usually begin at the top of tall and slender structures, pose a real risk for wind turbines. An EPFL study analyzes the mechanisms underlying this poorly understood phenomenon.

A United States park ranger was hit by lightning on seven different occasions and survived all of them. He died from a self-inflicted gunshot wound at the age of 71 over an unrequited love!
Roy Cleveland Sullivan was a United States park ranger in Shenandoah National Park in Virginia. Between 1942 and 1977, Sullivan was hit by lightning on seven different occasions and survived all of them. For this reason, he gained a nickname "Human Lightning Conductor" or "Human Lightning Rod". Sullivan is recognized by Guinness World Records as the person struck by lightning more recorded times than any other human being. He died from a self-inflicted gunshot wound at the age of 71 over an unrequited love.

On July 13, 1977, New York City endured a 25-hour blackout after lightning strikes power lines, prompting widespread arson, looting, and riots. The blackout was to many a metaphor for the gloom that had already settled on the city. An economic decline, coupled with rising crime rates and the panic-provoking (and paranoia-inducing) Son of Sam murders, had combined to make the late 1970s New York’s Dark Ages.

Animals get struck by lightning, too.
Lightning strikes about 100 times every second of the day, mainly in warmer regions of the world. About 240,000 people are injured by lightning every year, and 24,000 die after being struck. But humans aren’t the only victims of lightning — animals are, too, though reports of such deaths are far rarer than the deaths themselves.

...Lightning strikes Catatumbo River in northern Venezuela 280 times per hour, 260 nights per year!
A lightning storm rages almost constantly at the mouth of the Catatumbo River in northern Venezuela, with bolts striking up to 280 times per hour for 10 hours a day, on 260 nights every year. That's 28 lightning strikes per minute for those nights - and about 1.2 million lightning strikes each year.
Venezuela, home of the delicious pabellón criollo, has been experiencing the Catatumbo lightning for hundreds of years now. It comes from storm clouds that amass more than 3,200 feet above the spot where the Catatumbo River flows into Lake Maracaibo. According to meteorologists, winds going across the lake and its surrounding swamps are likely responsible for the storms. The swamps are plains surrounded by mountains - the Andes (home of the first cultivation of quinoa), the Perijá Mountains, and the Cordillera de Mérida - and the combination of heat and moisture in the area creates electrical charges that - when met with wind destabilized by the mountain ridges - turns into lightning and thunderstorms.
Light flashes from the storm can be seen up to 25 miles away, earning the phenomenon the nickname "The Maracaibo Beacon," and it's been used by ships for navigation as a result.
The frequency of the lightning strikes changes both within the year and from one year to the next. October's wet season is peak time for the storms, while they generally calm down in January and February. In fact, there was a break in the storm due to a drought between January and March of 2010, and locals feared that the phenomenon was over for good.
The Catatumbo lightning holds a special place in the heart of Venezuelans, because it may have been partially responsible for the nation's independence. An attempted surprise attack led by British navigator Sir Francis Drake on the Spanish army was spoiled by the bright lightning one night in 1595, a story that was later recounted in Lope de Vega's epic La Dragontea a few years later. Years later, in the early nineteenth century, the Spanish army itself attempted a sneak attack on Maracaibo in order to take back the country towards the end of the Venezuelan War of Independence. Again, the Catatumbo lightning lit up the landscape, thwarting the invasion and allowing Venezuela's beloved revolutionary hero, Simón Bolívar, and his fleet to win one of the last and most important battles in the wars against the Spanish for independence.
The Catatumbo lightning has also been responsible for producing more ozone at the mouth of the Catatumbo than any other place in the world. Scientists have expressed doubt, however, that this will have any effect on the world's ozone layer, due to the lightning's instability. Its effect on tourism, however, is not in doubt, as sightseers have flocked to the region to join nighttime tours to see the lightning. It's a great addition to any South American itinerary.

An incredible 45 day storm turned California into a 300-mile-long sea — and it could happen again.
A massive 19th century storm in the pacific United States opened up a 300-mile-long sea that stretched through much of the central part of California. For 43 days, from late 1861 to early 1862, it rained almost nonstop in central California. Rivers running down the Sierra Nevada mountains turned into torrents that swept entire towns away.

Volcano eruptions can produce lightning!
Mount Etna spectacularly exploded on the 3rd of December 2015 for the first time in two years, sending a plume of volcanic ash scorching through the sky. The cloud was lit up with the astonishing sight of a "dirty thunderstorm", which causes lightning to streak through a cloud of ash. This natural wonder occurs when tiny fragments of rock, ash and ice rub together to produce static electricity.

Storm sank 4 ships on Lake Erie in 1916
Some call it Lake Erie’s “perfect storm,” one so powerful 100 years ago that it caused four ships to sink within 18 hours.
In all, 49 lives were lost in the lake’s Canadian waters, but those crew members are being remembered right here in Toledo.
“This massive [storm] affected communities across the lake,” said Carrie Snowden, archaeological director for the Toledo-based National Museum of the Great Lakes, and who is giving a presentation about the storm during a lecture series today. “This storm is Lake Erie’s own perfect storm; this coming together of different weather fronts to create something horrific on top of Lake Erie. The human loss is of greater significance.”

Tiny lightning bolt explosions can vaporise the moon’s thin soil
Mini-lightning may flash in the coldest craters on the moon, melting and vapourising soil. All that sparking could have altered the surface as much as impacts from incoming rocks and dust.
The outer layer of the moon is a sort of history book recording the interactions between the moon and the rest of the solar system. To correctly interpret that history, we need to understand the mechanisms that shape it.

Lightning Makes For A Terrible Renewable Energy Source
Lightning is an impressive, energetic force of nature — so why aren't we using all that raw power to run our homes? Two reasons:
For one thing, lightning is unpredictable and really, really fast.
The second part of the answer: It's hot and loud and bright, but lightning doesn't carry as much energy as you might think.

..that ship-emitted particles and increase lightning?
MODERN, broad-beamed merchant vessels are well able to withstand the rough and tumble of the waves, but sailors still prefer to avoid storms at sea if they can. Containers may come loose in heavy weather and there is always a chance of lightning knocking out communications. It is therefore ironic that some storms may be caused by ships themselves. That, at least, is the conclusion reached by Joel Thornton of the University of Washington, in Seattle, and his colleagues in a paper just published in Geophysical Research Letters. They demonstrate that lightning strikes the Indian Ocean and the South China Sea almost twice as often along shipping lanes as it does other areas of these waters.
Dr Thornton and his team considered 1.5bn strikes recorded in this part of the world by the World Wide Lightning Location Network (an international collaboration led by Dr Thornton’s colleague, Robert Holzworth) between 2005 and 2016. As the map shows, those strikes that happened over the ocean were concentrated in places most plied by ships. In particular, the shipping lane that passes from the south of Sri Lanka to the northern entrance of the Straits of Malacca, and thence down the straits to Singapore, positively glows with lightning. (Its westward extension to the Suez canal was outside the study area.) So do the lanes from Singapore and the western part of Malaysia that head north-east across the South China Sea.
Neither changes in vertical wind shear nor differences in horizontal air movements seem likely to be causing this concentration of thunderstorms, for other measurements suggest that these weather-modifying phenomena are the same inside shipping lanes as they are in neighbouring parts of the atmosphere immediately outside those lanes. Nor does it seem plausible that the ships themselves (admittedly made of metal, and also the tallest structures on what is otherwise a flat surface) are responsible for attracting all the extra strikes involved. Though the area of the lanes is small compared with the whole ocean, it is vast compared with the area actually occupied by vessels. Most of the extra bolts are hitting the sea rather than craft sailing across it.
The most likely explanation is particulate pollution emitted by the ships using the shipping lanes. Marine diesel burned offshore is generally high in sulphur, and its combustion produces soluble oxides of that element which act as nuclei for the condensation of cloud-forming droplets. Typical marine clouds in unpolluted areas are composed of large droplets and do not rise to high altitude, but Dr Thornton and his team reckon that smaller droplets, of the sort that condense around oxides of sulphur, might more easily be carried upward by convection—forming, as they rose, into towering storm clouds that would act as nurseries of lightning bolts.
As to what can be done about this extra lightning, change may already be in hand. At the moment, standard “bunker” fuel has an average sulphur content of 2.7%. From 2020 that should fall to 0.5% if refiners and shipowners obey rules being introduced by the International Maritime Organisation, the body responsible for trying to impose order on the world’s shipping.
Ships are also being sailed more efficiently, often by slowing them down, which reduces the amount of fuel consumed per nautical mile. That is how Maersk Line—one of the world’s biggest container-ship operators—has cut its fleet’s fuel consumption by 42% since 2007.
On top of this, ship propulsion is becoming more efficient, as heat-recycling systems and new types of engine are introduced. In a few decades, therefore, the storminess of shipping lanes may have returned to normal. In the meantime, for any who may doubt humanity’s ability to affect the weather, Dr Thornton’s work provides strong evidence that it can.

Earthquake lightning?
What was that strange light in the sky?
Many people overnight reported seeing strange lights in the sky, a phenomenon that has been reported for centuries before, during, and after earthquakes.
Seismologists aren't in agreement about the causes of the hotly-debated phenomenon - called earthquake lights or, sometimes, earthquake lightning.
And, of course, it's not clear whether the lights overnight in New Zealand were the phenomenon, or something else.
One theory suggests dormant electrical charges in rocks are triggered by the stress of the Earth's crust and plate tectonics, transferring the charge to the surface where it appears as light.
Historical reports include globes, or orbs, of glowing light, floating just above the ground or in the sky.
Much like tidal research, it is an area that is notoriously difficult to investigate. Tidal stresses and their effects on the Earth are minute, but measurable, although many seismologists remain unconvinced by theories of "tidally triggered" earthquakes.
With "earthquake light", the phenomenon is also notoriously difficult to observe, study, and measure.
GNS seismologist Caroline Holden said there were anecdotal reports of lights in the sky.
"Unfortunately, we cannot measure this phenomena or its extent with our instruments to provide a clear explanation," she said.
The phenomenon has been documented for centuries.
Hypotheses have suggested the movement of rocks could generate an electric field, others suggest quakes can lead to rocks conducting electromagnetic energy and a subsequent build up of electric charges in the upper atmosphere.
Yet another theory suggests a link between the electric charge, or current, released by the earth ripping and buckling below the surface, and the magnetic properties of rock.
The charge appears as light, so the theory goes.
People reported similar strange lights in the sky during the 2011 Christchurch earthquake.
In 1888, before a large quake around the Hanmer region, a strange glow in the sky was reported by observers.
One recent study documented hundreds of sightings of strange light, glowing, and aurora-like reports, from 1600 to the 19th century.
The study in the Seismological Research Letters suggested a charge builds up in rock inside the Earth's crust and, as it becomes rapidly unstable in a quake, expands outward.
In an earthquake, the electrical charge transfers from below the surface to the surface, or above, depending on the conductivity of the rock - appearing as light.
"When such an intense charge state reaches the Earth's surface and crosses the ground–air interface, it is expected to cause [an electric transmission and breakdown] of the air and, hence, an outburst of light.
"This process is suspected to be responsible for flashes of light coming out of the ground and expanding to considerable heights at the time when seismic waves from a large earthquake pass by."
The study said some seismologists also think the theory could account for other phenomena, such as changes to electrical fields, strange fog, haze, clouds, and low-frequency humming or radio frequency emission.
In the study, the researchers found the light was more often associated with a type of quake in which tectonic plates are wrenched apart, known as a "rift" earthquake
