Climate Models Help Researchers Understand Atmospheric Electricity
2013-10-04 08:51:04

April Flowers for redOrbit.com - Your Universe Online A detectable electrification of the air is caused by electrical currents born from thunderstorms. These currents flow through the atmosphere around the globe, even in places with no thunderstorm activity. Until recently, however, science has not had a good explanation for how conductivity varies throughout the atmosphere and how that may affect the path of the electrical currents. A new study led by the University of Colorado...

New Work May Be Key To Avoiding Large-scale Power Outages
2013-09-27 12:40:33

American Institute of Physics Streamers may be great for decorating a child's party, but in dielectrics, they are the primary origin of electric breakdown. They can cause catastrophic damage to electrical equipment, harm the surrounding environment, and lead to large-scale power outages. Understanding streamers and the mechanisms behind their initiation, acceleration and branching is necessary to devise better solutions to avoid them. As recently reported in the Journal of Applied...

Super-rapid Intensification Of Supertyphoon Usagi
2013-09-20 11:22:06

NASA The radar on the Tropical Rainfall Measuring Mission (TRMM) satellite captured an image of Supertyphoon Usagi near the end of a 24-hour period in which Usagi intensified by 65 knots. This is more than twice the commonly used 30-knot threshold for defining rapid intensification. The TRMM data was used to create a 3-D image. The data was collected at 1035 UTC/6:35 a.m. EDT on Thursday, September 19, 2013, when Usagi was at category 3 on the Saffir-Simpson hurricane intensity scale. ...

NASA Firestation To Track Strange Things Produced By Thunderstorms
2013-09-11 12:32:12

[ Watch the Video: Firestation To Investigate Thunderstorm Tops ] Lee Rannals for redOrbit.com - Your Universe Online A new experiment aboard the International Space Station (ISS) is looking into the strange things that come from the tops of thunderstorms. The experiment, called "Firestation" consists of a package of sensors designed to explore how the Earth mimics a supernova during thunderstorms. About 50 times a second bolts of lightning heat up the air to a temperature five times...

Air Force Scientists Share Insights About Lab-Created Ball Lightning
2013-08-20 13:15:52

Lee Rannals for redOrbit.com - Your Universe Online Ball lightning is a phenomenon that has puzzled some of the best minds for generations, including Aristotle and Nikola Tesla. Now, scientists from the US Air Force Academy say they have some new insights into reproducing the rare form of lightning in the laboratory. The phenomenon consists of a floating, glowing ball that drifts eerily through the sky and then explodes violently. It sometimes can injure people and damage buildings....

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...
