Authorities are asking residents in some parts of south Australia to evacuate their homes as an impending heat wave prompted the nation to issue its first "catastrophic" brush fire warning. Unseasonably hot and dry weather combined with strong winds to fan scores of blazes in the country's southeastern states, many of which were sparked by overnight lightning strikes. Nathan Rees, New South Wales state premier, says, "It has never been this hot, dry or windy in combination in November ever...

TAU discovers an accurate tool for tracking solar rotation Sunspots, which rotate around the sun's surface, tell us a great deal about our own planet. Scientists rely on them, for instance, to measure the sun's rotation or to prepare long-range forecasts of the Earth's health. But there are some years, like this one, where it's not possible to see sunspots clearly. When we're at this "solar minimum," very few, if any, sunspots are visible from Earth. That poses a problem for scientists in a...

Every year, scientists learn something new about the inner workings of lightning. With satellites, they have discovered that more than 1.2 billion lightning flashes occur around the world every year. (Rwanda has the most flashes per square kilometer, while flashes are rare in polar regions.) Laboratory and field experiments have revealed that the core of some lightning bolts reaches 30,000 Kelvin (53,540 ºF), a temperature hot enough to instantly melt sand and break oxygen...

A powerful lightning storm in Saturn's atmosphere that began in mid-January 2009 has become the Solar System's longest continuously observed thunderstorm.  It broke the record duration of 7.5 months set by another thunderstorm observed on Saturn by NASA's Cassini spacecraft between November 2007 and July 2008. The observations of the thunderstorm will be presented by Dr Georg Fischer of the Austrian Academy of Sciences at the European Planetary Science Congress in Potsdam, Germany, on...

A freak bolt of lightning struck a 56-year-old cyclist in Englewood, Colo., even though no electrical storms were reported in the area, authorities say. Perry Schellpfeffer, an Englewood police spokesman, told The Denver Post the unidentified victim was hit by the lightning Wednesday afternoon. His injuries were not considered life-threatening. There were some clouds and it was thundering a little, but there wasn't any kind of lightning storm, Schellpfeffer said. Among U.S. states, Colorado...

GENEVA, August 31 /PRNewswire/ -- The dataset will provide lightning information throughout the globe to serve the world's meteorological institutions and other weather-dependent users. Consisting of lightning sensors distributed throughout the globe, the coverage and performance of Vaisala's Global Lightning Dataset (GLD360) is unique, global, and real-time. GLD360 outperforms satellite lightning detection by enabling uniform global coverage and by providing the timeliest...

U.S. scientists say they've captured a one-second image and the electrical fingerprint of a gigantic lightning jet that flowed 40 miles upward from a storm. While not occurring every time a thunderstorm develops, the rarely seen, highly charged meteorological events can flash up to the lower levels of space, or the ionosphere, Duke University scientists said. They are substantially larger than their downward striking cousins. Despite poor viewing conditions as a result of a full moon and a...

Duke University researchers have captured images of lightning bolts shooting upwards. The rare phenomenon, known as "gigantic jets," was photographed during tropical storm Cristobal last year. The gigantic jets shot more than 40 miles high, Duke Professor Steven Cummer and colleagues wrote in the journal Nature Geoscience. "Despite poor viewing conditions as a result of a full moon and a hazy atmosphere, we were able to clearly capture the gigantic jet," said Cummer. "What we were able to...

Utilizing fractal patterns similar to those created by lightning strikes, Victor Ugaz, associate professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University, has created a network of microchannels that could advance the field of tissue engineering by serving as a three-dimensional vasculature for the support of larger tissue constructs, such as human organs.Ugaz's work, which was undertaken with colleague Arul Jayaraman and appears in the July online version...

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...
