Volcanoes and lightning storms are awe-inspiring, fear-inducing feats of nature. Put them together and you have a truly terrifying event. Volcanic lightning is a mysterious phenomenon that generally occurs at the early stages of a volcanic eruption, and its taken scientists many years to determine its exact cause. It happens in two places: close to the ground in dense ash clouds, and high up near the stratosphere in the plume of volcanic smoke. For volcanic lightning near the ground, research suggests the cause is the rubbing together of individual ash particles, which builds up enough static electricity to generate a lightning bolt. Sky-high volcanic lightning has a more surprising cause: ice. Scientists think that as the plume of ash and water vapor rises from the volcano, ice begins to form in its highest layers. From there, lightning forms the same way it does in a thundercloud: ice crystals colliding build up enough of an electric charge to trigger a lightning strike. Want to see volcanic
Peer and Kendl firmly believe that lightnings magnetic fields have a similar effect on humans as the TMS, and that a good percentage of ball lightning reports belong with pink elephants and still blue waters floating across the horizon of an arid desert.. In the words of John Abrahamson, a chemist and ball lightning expert at the University of Canterbury in New Zealand:. "The researchers make a convincing argument that some ball lightning reports are spurred by hallucinations, but I cannot believe that most of the images reported as ball lightning are due to this brain influence… The colors of light seen by the subjects in the experiment were white, gray, or in unsaturated colors, but. ball lightning has been reported in a variety of colors, including orange, green, and blue.". Eli Jerby, an engineer at Tel Aviv University in Israel, whose laboratory has produced something very similar to a lightning ball, agrees with Abrahamson. He says:. "While hallucinations could explain some cases, the ...
Total lightning probability forecasts for 26 mostly springtime days and 27 summertime days were analyzed for their usefulness and economic value. The mostly springtime forecast days had a relatively high number of severe weather reports compared with the summertime forecast days. The lightning forecasts were made with a dynamic lightning forecast scheme (DLS), and each forecast dataset used lightning assimilation to hasten convective initiation and, in most cases, to improve short-term forecasts. A spatial smoothing parameter σ of 48 km yielded more skillful, reliable, and economically valuable hourly forecasts than other values of σ. Mostly springtime forecasts were more skillful and had more hours of useful skill than summertime forecasts, but the latter still demonstrated useful skill during the first two forecast hours. The DLS forecasts were compared to those obtained with the "McCaul" diagnostic scheme, which diagnoses lightning flash data. The DLS had significantly higher fractions ...
The probability of lightning striking a particular object situated on the earth (ground) is found by multiplying the object s lightning-attractive area by the local ground-flash density (lightning strikes to ground per km2 per year). The following example considers a low structure surrounded by 12 tall, grounded metal light poles.. Caveats: It must be understood that calculations used for determining strike probability are based upon empirical relationships, generally accepted by the research community as reasonably representing the lightning phenomenon. The method presented here provides a reasonable estimate but should not be considered the final word. Other, more complicated geometric methods can be used but, considering the capricious nature of lightning, it is unlikely they would provide significantly improved results.. A complete cloud-to-ground lightning event, referred to as a flash, consists of one or more return strokes. Return strokes are high-peak-amplitude (tens to hundreds of ...
redOrbit Meteorologist Joshua Kelly. The week of June 24-June 30 is noted as "Lightning Safety Week". So what are some things that you can do when you hear the first crackle of thunder? One of the first things to do is take cover inside a shelter such as a house, garage or even patio. The next thing you can do to help prevent injury is not run for cover under a tree or object outside that can easily be attracted to lightning. A third thing is try to avoid using appliances and electronics that are plugged into the wall during a thunderstorm as lightning is attracted to these types of objects.. There are many types of lightning that spread through the sky during a thunderstorm. The one that is seen in the image above is the most significant one to humans on Earth and that is "Cloud to Ground Lightning" which is when the lighting is released from the cloud and strikes directly towards the Earth´s Surface.. One fact about lightning is that it is warmer than the Sun´s surface, so if it directly ...

NASAs Cassini spacecraft captured an image of lightning striking within a huge storm that encircled Saturns northern hemisphere, providing scientists with a great opportunity to see how weather plays out at different places in our solar system.. Pasadena, California - Saturn was playing the lightning storm blues. NASAs Cassini spacecraft has captured images of last years storm on Saturn, the largest storm seen up-close at the planet, with bluish spots in the middle of swirling clouds. Those bluish spots indicate flashes of lightning and mark the first time scientists have detected lightning in visible wavelengths on the side of Saturn illuminated by the sun.. "We didnt think wed see lightning on Saturns day side - only its night side," said Ulyana Dyudina, a Cassini imaging team associate based at the California Institute of Technology in Pasadena. "The fact that Cassini was able to detect the lightning means that it was very intense.". Images can be found at http://www.nasa.gov/cassini, ...

Did you know the highest number of people being struck by lightning occurs in the summer? A lightning strike has the temperature of 50,000 degrees Fahrenheit which is hotter than the surface of the Sun, but fortunately most people who are hit by lightning survive. Less than 10% die each year from a lightning strike, still approximately 58 people do. Even though most dont die when struck by lightning, they do deal with severe and long term effects.. Lightning can travel up to 10 miles from a storm. If you can hear thunder you are in an area where you can be hit by lightning. If you feel your hair beginning to stand, this is a bad sign. Seek shelter immediately, but stay away from trees and metal objects such as a shed. Get low and stay low, do not become the highest surface around. The best shelter is in a house. Realize you can still be in harms way. Lightning can travel through windows, doors and wires. So stay away from the windows or doors and do not use the telephone. Most lightning ...

2000-10-27 04:00:00 PDT Milpitas -- A lightning strike left 24,000 South Bay customers without electricity for more than two hours last night, Pacific Gas and Electric Co. officials said. The power failure hit about 20,000 customers in Milpitas and 4,000 in northern San Jose. Repair scrambled to remedy the power failure last night, said Jonathan Franks, a PG&E spokesman. Lightning struck a transmission line or substation in the area at 4:55 p.m., he said. Power was restored at 7:15 p.m. Milpitas and San Jose police reported no major problems because of to the power failure.
A more "down to Earth" explanation was proposed in a 1999 Letter to Nature: John Abrahamson and James Dinniss conjectured that a ball lightning may be caused by the burning of small particles created when a normal lightning strikes on soil. The stroke of the lightning would vaporise and reduce silica in the soil into pure silicon vapour. As this vapour cools, they suggested, the silicon condenses into a floating aerosol bound by electric charges on its surface and forming some kind of bubble. Like the magnesium in the flashlight of an old-fashioned photographer, the pure silicon immediately burns in the oxygen of the surrounding air. This then creates the bright light and the smell of the ball lightning phenomenon, which then would be not an electric discharge, but a chemical reaction ...

An important weather challenge is to forecast lightning within a 20 mile radius of the launch complexes, 1-8 hours before a first strike, depending on the operation being supported. For instance a Shuttle landing requires a 90 minute lightning forecast, whereas the movement of solid rocket boosters requires a four hour forecast, and the movement of the Shuttle to the launch pad requires an 8 hour forecast. Benefits of better forecasts include the safety of personnel and protection of multi-billion dollar rocket launching systems, payloads, and supporting infrastructure. Accurate lightning forecasts can save $1M by avoiding either a 24 hour launch delay or the need to land the Space Shuttle at another facility and transport it back to KSC ...

TAMPA -- Its all coming back now. That familiar anticipation. The tingling in the veins, followed by the quickening of the pulse. And then the three-to-zip score. Yup, the Lightning is back in the playoffs. Its been seven years, two ownership changes, one move across the bridge and a roster upheaval since the Lightning last saw the postseason. And, yet, Game 1 feels awfully familiar. Remarkable how long the wait seemed and how quickly the answer arrived. It took one period to get anxious, two periods to get impatient and three periods to wonder if a sellout was such a good idea after all. Oh, maybe it wasnt all that bad. Seven years ago, in that inaugural playoff game against the Flyers, it took about 42 seconds for the Lightning to spot its elders a 3-0 lead. This time, the fellas lasted darn near 42 minutes before being passed by faith and cross checked by reality. "The guys know now what the intensity level is in the playoffs," said captain Dave Andreychuk. "Theyll know better next game." ...
In their open-access paper for Geology, Kimberly Genareau and colleagues propose, for the first time, a mechanism for the generation of glass spherules in geologic deposits through the occurrence of volcanic lightning. The existence of fulgurites -- glassy products formed in rocks and sediments struck by cloud-to-ground lightning -- provide direct evidence that geologic materials can be melted via natural lightning occurrence.
Think of the ice at Amalie Arena as a giant windshield.. Now think of the Tampa Bay Lightning as a bug.. Splat.. Got it?. The Lightning, playing so well as of late, were clobbered at home in Thursday nights game, losing 5-0 to the Toronto Maple Leafs. The Bolts, who had just passed the Leafs in the standings, now are playing chance once again.. Lightning coach Jon Cooper said it was his teams defense, which had been good lately, that led to the defeat.. "The thing that was missing was the defending of shots," said Cooper. "Thats the thing we werent doing. There is a spot 10 feet out, this little 10×10 area in front of our net. That was the only area of the ice we didnt play. Clearly, thats the most important part (on the ice.) Weve been so good defending as of late. Thats why weve had success, and tonight, we didnt (defend.)

Jan. 19, 2002: Pascal Rheaume, a forward for the NHLs Atlanta Thrashers, set career highs and franchise records with four goals and five points in a single game against the Florida Panthers. That night, the spotlight had finally fallen on another member of the Rheaume family. And no one was happier than Pascals older sister. "I got a message on my phone about the game," said Manon Rheaume, formerly of the Tampa Bay Lightning. "I was so excited, I couldnt go to bed." There was a time when Manon was the focus of the medias attention. Her name was scrawled into the history books on Sept. 23, 1992, when she stepped on the ice to play goalie for the Lightning in a preseason game, becoming the first and only woman to play in a major mens sports league. The decade that has passed since Rheaumes debut has brought an explosion of womens sports: professional leagues in womens basketball and soccer, and womens softball and ice hockey have become Olympic events.
