Hello:
I am curreently collaborating in some research regarding a Native American Sacred Site in Arizona. While this is more of a Geological/Archeological study, recently we have felt the need to obtain some meteorological expertise and input. This site has a significant number of petroglyphs depicting lightning in a variety of forms. In fact, it seems to be the focus of the site symbology. After a time, we did notice and verify through lightning strike maps that there does seeem to be an abnormally high degree of electrical activity at the site. As a result, we decided to document some of this activity and the footage seems a little strange to us. We have documented a good amount of positive lightning coming from the mountain where the ruins reside. Additionally, there seems to be some activity that we are not familiar with. This is best described as some type of electrical stimulus-response activity that originates from the mountain. We have repeatedly documented low intensity ground discharges that seem to generate air to ground lightning to the specific spot on the mountain. Also, the lightning recorded above the site seems to exhibit some interesting characteristics best described as discharges with almost perfect mirror symmetry. I have included links to examples below. http://www.worldblend.net/worldblend...nganalysis.wmv http://www.worldblend.net/worldblend...ES/symlght.wmv I would appreciate any comments regarding the nature of this activity and what may be taking place here. Regards, WB |

I suspect if you were to capture video of lightning at other mountainous locations, you'd see similar kinds of things. Most lightning flashes involve a complex sequence of invisible pilot leaders moving downward, brilliant return strokes moving upward, and multiple recharge/flash cycles. This sequence is generally not detectable by the naked eye, and even your video probably isn't sensitive enough (or fast enough) to pick up some of the more subtle exchanges. I'm wondering whether the "spherical" points of light moving upward might have been lens reflections trigged by a lightning flash outside of the nominal field of view. Just a thought... http://www.worldblend.net/worldblend...ES/symlght.wmv didn't check this one yet, but will when I have more time. I would appreciate any comments regarding the nature of this activity and what may be taking place here. Regards, WB |

![]() http://www.worldblend.net/worldblend...ES/symlght.wmv didn't check this one yet, but will when I have more time. Okay, now I have. Looks to my eye like fairly ordinary in-cloud (or cloud-to-cloud) lightning. I think the the "mirror symmetry" is probably just a statistical fluke coupled with the brain's tendency to want to impose order .. if you toss a few strands of spaghetti on the floor, there's bound to be a few from time to time that exhibit some of kind of "meaningful" shape to your eye. Just an opinion .. maybe I'm overlooking the particular feature you're referring to. In any case, I can't think of any physical reason why a lightning channel might prefer mirror symmetry over any other kind of fractal path. |

Bushy Salami states that pilots should lie to Medical Examiniers during their physical exams! By this type of behavior, the process is screwed up when individuals do such things! This is the same guy who praises Belfort Instruments and loves to hea | sci.geo.meteorology (Meteorology) | |||
