Most people know to unplug computers to prevent lightning damage but some are injured by lightning using hardwired video games, a U.S. researcher says. Dr. Mary Ann Cooper, director of the lightning injury research program at the University of Illinois at Chicago, notes an increasing number of people injured indoors using Play Stations and other such video games. Cell phones, iPods and other wireless devices do not attract lightning but they may distract people from paying attention to the...

U.S. scientists say they have detected the first direct evidence of lightning occurring on Mars. University of Michigan researchers said they found signs of electrical discharges during dust storms on the red planet. The bolts were dry lightning, Professor Chris Ruf said. What we saw on Mars was a series of huge and sudden electrical discharges caused by a large dust storm, Ruf said. Clearly, there was no rain associated with the electrical discharges on Mars. However, the implied...

U.S. scientists are using high-energy particles from space in an attempt to solve one of nature's mysteries -- how thunderstorms create lightning. Florida Institute of Technology researchers Joseph Dwyer and Hamid Rassoul, with Martin Uman from the University of Florida, have developed a technique to remotely measure thunderstorm electrical fields on the ground. They said by measuring small radio pulses made by cosmic-rays passing through the storms, they might be able to reconstruct the...

Experts say passenger jets are hit by lightning every 1,000 hours (on average twice a year) and the risk from the bolts of electricity continues to be an increasing problem, AFP reported. However, after the disappearance of an Air France jet in the Atlantic with the feared loss of 228 lives, technical experts say lightning alone could not have caused it to crash into the ocean. The A300-200 jet was likely hit by lightning as it passed through a violent storm on the flight from Rio de Janeiro...

Trying to find how thunderstorms create lightning Florida Institute of Technology researchers are trying to solve one of the great mysteries in nature: how thunderstorms make lightning. Because, in principle, lightning is a big spark it should behave like other sparks"”like the ones created when we touch a door knob on a dry day. Scientists have accumulated evidence, however, that lightning sometimes behaves in very un-spark-like ways. Lightning can start in regions of thunderstorms...

Lightning may provide scientists with crucial insight into predicting the intensity of Earth's deadliest storms. Each year, hurricanes pose threats of devastation around the world, and while forecasters have become better equipped to predict their pathways, they often find it difficult to gauge the storms' intensity in advance. Colin Price of Tel Aviv University in Israel and colleagues analyzed the correlation of growth of maximum winds and lightning frequency every 6 hours. Their study...

Collect first data on lightning during volcano's initial eruption Researchers hit the jackpot in late March, when, for the first time, they began recording data on lightning in a volcanic eruption--right from the start of the eruption. Using a multi-station, ground-based Lightning Mapping Array, the scientists advanced our understanding of electrical activity during a volcanic eruption. Portable Lightning Mapping Arrays are now set up in several areas of the country, and are becoming...

In legend, sprites are trolls, elves and other spirits that dance high above our ozone layer. But scientists at Tel Aviv University have discovered that some very real "sprites" are zipping across the atmosphere as well, providing a possible explanation for those other legendary denizens of the skies, UFOs. Thunderstorms, says Prof. Colin Price, head of the Geophysics and Planetary Sciences Department at Tel Aviv University, are the catalyst for a newly discovered natural phenomenon he calls...

Mu researcher releasing weather balloons during winter storms in search of phenomenon The job of one University of Missouri researcher could chill to the bone, but his research could make weather predicting more accurate. Patrick Market, associate professor of atmospheric science in the College of Agriculture, Food and Natural Resources, is chasing storms in the dead of winter in order to release weather balloons that will produce data about the little-known phenomenon of thundersnow. "One of...

When we think of thunderstorms we have to remember the deadliest part of those storms and that is the lightning that occurs with them. Lightning is found in many forms. The first type of lightning is known as cloud to cloud meaning that the electric charge travels from one cloud to the other. The second type of lightning is the Cloud to Air meaning the lighting moves from the cloud and enters the clear air of the sky. A third type of lightning is the cloud to ground. This is the most...

A lightning rod is a metal conductor mounted on the top of a building and connected through a wire to the ground to protect the building from lightning. The rod should conduct the electricity from a lightning strike down through the wire instead of passing through the building. The rod is just a single component in the lightning protections system along with rooftop conductors and multiple conductive paths. Benjamin Franklin invented the lightning rod in 1749. The taller the building the...

Heat Lightning is actually faint flashes of lightning reflecting outward from distant thunderstorms. These flashes usually do not produce thunder as the storm is sometimes too far away to be heard. The term heat lightning got its name because it often occurs on hot summer nights and does not produce audible thunder. One reason heat lightning can be seen so far away is due to the reflection of the light bouncing off water particles in moist, humid air and as light is scattered throughout the...
