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.

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.

...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.

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.

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.”

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.

Lightning protection tents exist!
The probability of getting struck by lightning is statistically very rare, but alas, storm-attributed deaths and injuries stretch into the low thousands on an annual basis. About 96% of those struck were in open environments when hit. A majority — as you may expect — come from frequent participators in outdoor activities such as hiking, camping, and climbing. Industrial designer kama jania’s ‘bolt’ line of tents was created to increase the safety of those unfortunate to be in the wrong place when the weather turns.

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.

A 36-year-old diver was killed after lightning struck his oxygen tank!
A 36-year-old diver was killed off a Florida beach after lightning struck his oxygen tank, authorities have said. The man was diving with three others off a boat near Deerfield Beach on Sunday. When he surfaced, ‘lighting struck his tank,’ said Deerfield Beach fire Chief Gary Fernaays. ‘He was approximately 30 feet from the boat at the time.’

…thundersnow???
In the midst of a bizarre winter, Montrealers were treated to a rare sight on Monday night — a winter thunderstorm. Montrealers Jolyane Limoges and Pierre-Marc Doucet managed to capture the phenomenon during a snow squall, and post it on YouTube. The phenomenon is known as thundersnow — it's like a normal thunderstorm, but with snow as the primary form of precipitation. Thundersnow events happen when a mass of cold air settles on top of warm air, coupled with moist air closer to the ground.

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.

A teenage girl survived a terrifying lightning strike, saved by her iPod wire!
A teenage girl survived a terrifying lightning strike after she was saved by the wire of her iPod. Schoolgirl Sophie Frost and her boyfriend Mason Billington, both 14, stopped to shelter under a tree when a storm struck as they were walking near their homes. They were struck by a lightning but survived! Doctors believe Sophie survived the 300,000-volt surge only because it travelled through the gadget’s wire, diverting it away from her vital organs.

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.”

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.
