Lightning can strike at sea!

In a rare incident of its kind, a coastguard diver and a citizen were killed after they were struck by a lightning bolt off Khairan beach of Kuwait on the 8th of May 2016. The Interior Ministry said in a statement that a jet ski of citizen Saad Khaled Al-Shereeda broke down and a coastguard boat was dispatched to rescue him. The ministry added that the coastguard diver, Abdullah Othman Al-Doussary, jumped in the water to help the man, but they were both struck by lightning and were killed instantly. In October last year, an Asian was killed by lightning in northern Kuwait during a freak storm. It is estimated that 6,000 to as many as 24,000 people are killed around the world by lightning strikes every year.

Why is lightning white?

Static charges form in a storm composed of ice crystals and liquid water drops. Turbulent winds inside the storm cause particles to rub against one another, causing electrons to be stripped off, making the particles either negatively or positively charged. The charges get grouped in the cloud, often negatively charged near the bottom of the cloud and positively charged up high. This is an electric field and because air is a good insulator, the electric field becomes incredibly strong. Eventually a lightning bolt happens and the flow of electrons neutralizes the electric field. This flow of electrons through the lightning bolt creates a very hot plasma, as hot as 50,000 degrees, that emits a spectrum of electromagnetic energy. Some of this radiation is in the form of radio waves and gamma rays. Instruments that measure these electromagnetic waves allow us to detect lightning bolts that are very far away. Visible light is also part of the spectrum of energy. At these temperatures, laws of physics state that most of the visible light will be at a wavelength perceived as the color blue, although all wavelengths will be emitted. The notion of color applies to our perception of what we see, not to the light itself. When we talk about the color of light, we really mean the color we sense with our eyes and then interpret with our mind. Thus, while the peak energy is at blue wavelengths, the intensity of all the colors tends to saturate our eyes, leading us to perceive the color white – which includes all wavelengths in the visible spectrum. Over the last 20 years scientists have discovered that lightning also shoots upward out of the top of thunderstorms into the upper atmosphere. These lightning types have distinctive colors, including red sprites and blue jets.

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.”

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.

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.

Lightning knocked out Internet on Cayman’s Island!

A lightning strike along one of the submarine cables that connects Cayman’s Internet to the rest of the world knocked out Internet service for many on Grand Cayman Tuesday evening. The lightning hit a landing station at the U.S. end of the Maya-1 cable system between Cancun, Mexico and Hollywood, Florida, on Tuesday afternoon, affecting Internet access and some phone service in Cayman, according to local telecom companies and regulators.

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.

On the 21st of August 2011, a thunderstorm forced the Pope to cut short his speech!

On the 21st of August 2011, a thunderstorm forced the pope to cut short his speech to an estimated 1 million young pilgrims gathered at a Madrid airfield to mark World Youth Day. As rain soaked the crowd and lightning lit up the night sky on Saturday, the 84-year-old pontiff skipped the bulk of the speech and delivered brief greetings in half a dozen languages.

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 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.

...what a moonbow is?

Moonbows, also known as lunar rainbows, are the dimmer cousin of more common daylight rainbows, made possible from the refraction of raindrops by moonlight, rather than sunlight. Moonbows are so rare because moonlight is not usually bright, and the alignment of conditions needed for them don't happen often. According to Atmospheric Optics, a bright near-full moon must be less than 42 degrees above the horizon, illuminating rain on the opposite side of a dark sky.

Lightning caused deaths are fewer every year, at least in the US!

This decade will go down in weather history as one of the wildest in modern times. Since 2010, we’ve seen both the widest and strongest tornado on record touch down in Oklahoma. Mexico felt the wrath of the strongest hurricane ever recorded in terms of wind speed. The American West is enduring a years-long drought with no end in sight. But it’s not all bad news. This decade is also on track to see the lowest number of lightning deaths we’ve ever recorded in the United States, and that’s quite the accomplishment.

A man was blown out of boots after being hit by a lightning bolt!

A man in Atlanta, USA was lucky to be alive after he was struck by lightning, blowing him right out of his work boots. Sean O’Connor was doing yard work Saturday when he was struck by a bolt of lightning and knocked unconscious. According to the 30-year-old, the sun was shining and there appeared to be no threat of storms when he began working in his yard.

Animals can have storm phobia!

According to WbMD, storm phobia is very real and should be taken seriously. Loyal masters are often awaken in the middle of the night – not from the thunder – but from the uninvited pet jumping in the bed looking for comfort from the storm. Cases of storm phobia in pets can be much more severe and should not be ignored. They say some pets have been known to “claw through drywall, chew carpets, or break through windows in their escalating panic.”

Almost half of drivers speed to avoid hail storms!

According to research from RACQ nearly half of Queensland, Australia drivers will speed to avoid hail damage to their cars. The motoring club and insurer's research revealed 47% of motorists admitted to speeding to avoid hail damage to their cars - up from 44% last year. The research also found female drivers were more likely to speed (54.2%) than males (52%) when a storm hits.
