NOTE: RCM data is susceptible to a phenomena called anomalous propagation. This generally happens at night and appears as a area of 20 Dbz echos (darkest green) which is centered around each radar site and expands with time. To try and reduce the problem, all radars in clear air mode have been eliminated from the summary. Therefore, some dark green areas at night may not not rain.

95. Lightning Facts A short compendium of information about lightning. http://home.earthlink.net/~jimlux/lfacts.htm

Lightning Facts A short compendium of information about lightning.  A typical lightning flash lasts about a quarter of a second and consists of 3 or 4 individual discharges called strokes. Each stroke lasts a few ten thousandths of a second, although the visual appearance is longer. The "flicker" sometimes observed in lightning is due to seeing the actual strokes making up the flash. A lightning stroke begins with a faint predischarge, called the leader, which goes from the cloud to the ground. The leader establishes a path for the highly luminous return stroke (what you really see) which propagates from the ground up to the cloud. The first stroke of a flash is usually preceded by a "stepped leader", so called because it appears to progress in discrete steps (about 100 segments, each 50 m long) from cloud to ground. The subsequent strokes are preceded by a "dart leader" which smoothly follows the path of the previous return stroke (and is about 10 times faster). Thunder is formed from the shock wave formed by the rapid heating of the air along the path of the return stroke, which reaches some 30,000 degrees K. The sound of thunder varies depending on how far you are from the various parts of the stroke. The sound from a part of the stroke farther away will get to you later and be fainter.

96. Tornadoes And Ball Lightning - Paper By Edward Lewis A Edward Lewis paper, with the discussion of ball lightning as plasmoids. http://www.padrak.com/ine/ELEWIS3.html

Return to the INE Main Page Tornadoes and Ball Lightning Edward Lewis P. O. Box 13050 Chicago, Illinois 60613 September 7, 1995; Revised July 22, 1996 and August 20, 1996 [Received via email to INE, June 1996. Revised Oct. 1996.] [Reposted Nov. 15, 1996.] Tornadoes and Ball Lightning Abstract Tornadoes and ball lightning are identified, and described as plasmoid phenomena. Certain anomalous characteristics of tornadoes and ball lightning are described and shown to be similar to the behavior of the plasmoid phenomena produced by electrolysis and discharge apparatus; in part, as evidenced by certain kinds of micrometer sized traces in nuclear emulsions and marks in materials. Atmospheric Plasmoid Phenomena A weather observer for the U. S. Weather Service named F. Montgomery(10) who was stationed in Blackwell, Oklahoma in May of 1955 reported a tornado that passed by in the evening at 9:27 P.M. that had a deep blue section that was near the top near the cloud layer and that was "very much brighter" than an arc welder and too bright for him to look at, though the tornado was 9 blocks or 3600 feet away from him. I suspect that the bright section may have been toroid shaped. He reported that the air from the tornado felt hot and that the temperature as recorded by a thermometer at his instrument shelter rose from 74 degrees Fahrenheit to 80 degrees Fahrenheit when the storm struck. This is evidence of a spectacular rate of radiation. And he reported: There were rapidly rotating clouds passing in front of the top of the funnel. These clouds were illuminated only by the luminous band of light. The light would grow dim when these clouds were in front, and then it would grow bright again as I could see between the clouds. As near as I can explain, I would say that the light was the same color as an electric arc welder but very much brighter. The light was so intense that I had to look away when there were no clouds in front. The light and the clouds seemed to be turning to the right like a beacon in a lighthouse(11).

97. The Virtual Times Unusual Experiences With Lightning Unusual experiences with lightning and ball lightning as related by eye witnesses. http://hsv.com/weather/unusual/

U nusual E xperiences with L ightning Subject: Ball Lightning There was no lightning around the immediate area, because the storm had passed about an hour before. The storm that had come through did have a lot of lightning and lot of dime sized hail, too. I think it was ball lightning that just exploded in our yard, or something like that. Wes Price Subject: Ball Lightning my experience Subject: Ball lightning . I do recall that, once again, the dog suddenly became eager to return home. I lived there another year and a half and never saw it again, but I somehow suspect the set up of that particular street-corner is particularly conducive to the formation of such balls. (I no longer live in that neighborhood or I'd still be keeping a look out). Sorry about the year - I should at least have thought to add that after reading the other reports.

100. Great Balls Of What? : Nature News An article from Nature.com. http://www.nature.com/nsu/000203/000203-8.html

Jump to main content Jump to navigation nature.com homepage ... Browse by subject Search This site All of nature.com Advanced search My account E-alert sign up RSS feed ... nature journal Published online 3 February 2000 News Great balls of what? Philip Ball reports on new claims that the strange phenomenon of ball lightning is simply a kind of glowing candy floss spun from earth. Philip Ball Of all the weird and wonderful phenomena of the natural world, few have attracted so much curiosity, mystery and downright crankiness as ball lightning. It has been documented since antiquity, and has purportedly been seen by one person in a hundred. Yet there is still no definitive scientific explanation for these glowing apparitions, nor has any scientist produced them under laboratory conditions. According to a new theory presented in Nature , ball lightning may be nothing more than a burning orb of fluffy silicon, generated when lightning strikes soil. Formed during thunderstorms, the balls are luminous spheres typically about the size of a child's head. They are said to float through the air at a constant distance from the ground, occasionally jumping vertically or descending from the clouds. They pass through closed windows and doors and down chimneys. Sometimes they emit an orange glow, sometimes a baleful blue. They may vanish with a violent explosion. It is hard to imagine a phenomenon that better mimics a ghostly visitation. Some of the finest minds in physics have attempted to explain ball lightning, including the Serbian inventor Nikola Tesla and the Russian physicist Pyotr Kapitsa. Most theories have regarded it as some kind of electrical discharge. Kapitsa's ideas led to the proposal that ball lightning is a kind of microwave laser, a wave-like excitation of the air that keeps its shape like a tidal bore in a river.
