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.

Lightning is one of the most destructive forces in nature. But for all the folklore and legends amassed over human history on lightning, we know surprisingly little about the inner workings of this powerful phenomenon, including something as simple as how the current that flows through a thunder-inducing flash is related to the temperature of the strike. "The basic physics of lightning, such as lightning initiation and lightning propagation, is not fully understood at this point," said Robert Moore, a lightning researcher from University of Florida in Gainesville. "We know the basics, but not the details. So when anybody makes headway, it is major news." Lightning causes more than $5 billion in damages every year in the U.S., as well as more fatalities than hurricanes. "A direct hit from a lightning strike can melt a power cable or start a forest fire, where the amount of heat from the lightning plays a major role," said Xiangchao Li, a scientist from China who specializes in lightning research. Li and his team discovered a mathematical relationship between the current intensity and the temperature inside lightning. Their result was published last month in the journal Scientific Reports. Although there are approximately 100,000 lightning strikes on Earth every single day, the randomness of the occurrences makes it difficult for scientists to study them in an effective or systematic way. So until Thor, the Norse god of lightning as well as other meteorological events, joins a lightning research team, scientists are left to their own devices. Luckily such a device does exist. Known as an impulse current generator system, the device can create artificial lightning with currents up to tens of thousands of amperes. For perspective, a household or automotive fuse is usually rated well below a hundred amperes, and an electric current of just a few amperes can easily kill you. A natural lightning strike typically carries around 20-30,000 amperes of current. Certainly there are other factors such as size and setting of natural lightning that cannot be replicated in a laboratory, but just in terms of sheer current output, the lightning generated by the device can really give Thor a run for his money. By using their artificial lightning system, Li and his team were able to dial up lightning strikes at will, with currents between 5,000 to 50,000 amperes. This resulted in artificial lightning strikes with temperatures as high as 17,000 F, twice as hot as the surface of the Sun. This creates a new problem -- at such high temperatures, a normal thermometer would explode. And even if it didn't, it wouldn't react quickly enough to register the temperature of the lightning strike. Fortunately, there is "light" in "lightning." Li and his team were able to record the lightning's temperature within a millisecond by measuring the intensity of the light at various wavelengths. After striking lightning at the same place over and over again, they concluded that the relationship between the current and temperature of lightning is a highly logarithmic one, meaning that the temperature difference between lightning strikes with 1,000 and 10,000 amperes is similar to those with 10,000 and 100,000 amperes. This result provides solid evidence for previous theoretical predictions that lacked the support of data. "The next step would be to compare with measurements from rocket triggered lightning, or natural lightning, which can be done throughout the U.S. or China," Moore suggested. That's right, rocket-triggered lightning. Essentially a glorified version of Benjamin Franklin's wired kite, scientists today have ways to siphon natural lightning from the sky by launching an electrically grounded rocket, as shown in the video below. With a better understanding of the physics of lightning, scientists can help engineers to improve current protocols and infrastructures to better deal with lightning -- from weather warning systems to the design of power grids. Perhaps we can one day limit the power of Thor to only smiting Loki on the silver screen.

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.”

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.

The 1991 Ice Storm was one of the most damaging storms in Rochester history. It all began 25 years ago on Thursday. We took a look back with a woman who experienced it herself. For residents in our area that were around, the ice storm that began 25 years ago was an event unlike most had ever seen before and the memories of that storm are still as vivid and fresh as they were in 1991.

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.

The place most likely to be struck by lightning in the world is one spot above Lake Maracaibo in Venezuela, according to new data. Over this mountain lake, there was a lightning show an astounding 297 days out of 365 days a year, on average. Even more surprising, the lightning strikes didn't occur just over the massive lake, but at one particular spot -- the point where the lake empties into the Catatumbo River, researchers said Dec. 14 at the annual meeting of the American Geophysical Union.

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.

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.
