Almost all of these observations have been anecdotal and too qualitative to be of use to scientists. Happily, some atmospheric scientists are now taking more interest in "rocket lightning" and those strange light flashes seen above storm clouds. First, though, one more anecdotal report, and then we'll summarize two recent scientific efforts to elucidate these phenomena. July 28, 1993. 150 miles south of Panama. From an aircraft flying at 33,000 feet. "I and another pilot in the cockpit of American Airlines Flight 912 were watching and circumnavigating a large cumulonimbus cloud. About five times, a large discharge of lightning at the top of and within the cloud was followed by a vertical shaft of blue light that propagated from the top of the cloud upward to 100,000 ft. "The beam was very straight and the color distinctly different from the lightning. At the top of this shaft, the column fanned out just before its disappearance. All the occurrences were identical. At least one also was witnessed by three other American pilots about 30 min. behind us on the same route." (Hammerstrom, John G.; "Mystery Lightning," Aviation Week , 139:6 , August 30, 1993. Cr.

Scientists have generally belittled suggestions that weather could have anything to do with the ponderous forces unleashed during a quake. Despite such authoritative pronouncements, many Californians, who have ample experience with seismic events, insist that quakes and weather are somehow connected. They may be right -- at least some of the time. In the five years following the 7.3 Landers earthquake of June 28, 1992, the frequency of smaller quakes has peaked reliably every September. However, before the Landers event, no such pattern is evident. One thought is that the average atmospheric pressure, which is lower in the summer months, reduces the downward pressure on the earth's crust enough to allow easier slippage along fault lines. This sounds reasonable, but why did this effect not occur before the Landers quake? The answer given is that perhaps the Landers event "sensitized" nearby faults!

The detonations were rather strong, shaking houses and even causing picture windows to fall out. In some instances, flashes of light and other luminous phenomena were reported. The sounds were characterized as "air quakes" by some scientists because they did not always register on seismographs, although they were usually recorded on air-pressure monitoring equipment. One's first inclination is to attribute such detonations to supersonic aircraft and missles, but the U.S . military immediately denied they were to blame. Seismic noises come to mind next, but the frequent failure to register the events on seismographs suggested an atmospheric phenomenon. The National Enquirer (January 24, 1978) rather predictably linked the booms to UFOs. In the federal government, the Naval Research Laboratory (NRL) was assigned the task of tracking down the booms. In March, NRL reported that all of the 183 detonations they investigated were due to supersonic aircraft. That seemed to end the matter -- just as the Condon Report signalled the demise of UFOs!! The booms had an interesting side effect: they triggered urgent requests for the two Strange Phenomena sourcebooks from several universities, think-tanks, and intelligence agencies.

But the discharge paths followed by lightning strokes often seem unnecessarily tortuous when more direct routes are readily available. The mechanism by which large reservoirs of unlike charges are built up is also obscure. Cosmic rays have now been pro-posed as both a source of charged particles and a provider of low-resistance ionized conduits for lightning to follow. Primary cosmic rays carry considerable energy, most of which appears near the earth's surface in the form of cascades of secondary particles that create complex ionized tracks as they penetrate the dense lower atmosphere. Lightning bolts would tend to follow these precursors along their crooked trails. (Anonymous; "Do Cosmic Rays Trigger Lightning Discharges?" New Scientist, 77:88, 1978.) Comment.

Nicely symmetric discs are manufactured. But if an external electrical field (about 14 volts/cm) is applied across the nutrient medium, the regeneration geometry is distorted.

Seen by hundreds, it generated many high quality reports. Fifteen of the written reports mentioned anomalous sounds -- hisses, hums, swishes, and crackling sounds heard simultaneously with the visual sighting. Such sounds are anomalous because the meteor is tens of kilometers high and real sound would take a minute or more to reach the ground. (The sound from a detonating meteor is often heard several minutes later.) Keay is convinced of the reality of the anomalous sounds and suggests that the highly turbulent plasma in the meteor wake generates powerful electromagnetic radiation at audio frequencies. This intense radio energy reaches the earth at the same time the visible light does. It may be converted into sound as it interacts with the surface and the observer.

It is so hot there that some metal compounds of chlorine, fluorine, and sulfur are vaporized in some locales. Such metallic "mists" could well coat out as "frost" on the cooler, higher elevations. Actually, two outstanding Venusian anomalies can be explained by such metallic "frosts." Radar signals from earth are strongly reflected from the planet's mountains and high plateaus. These regions may owe their unusually high reflectance to metallic "frosts" consisting of such radarbright minerals as pyrite, which is probably present in vapor form at lower, hotter elevations.

Communicated to the crust, these slight taps trigger tiny earthquakes that relieve stresses beneath volcanos, thus delaying their eruptions until solar acitivity dies down. Not especially convincing!

The so-called satellite circles that sometimes array themselves around the main circles may be connected by a narrow ring, thus: Even more curious, a short radial spur extends outward from some circles, so that from the air the circle resembles a fat tadpole. In his book, G.T . Meaden, the Editor of the Journal of Meteorology, U.K ., presents his theory of how the circles are incised in field crops: "He describes the clues that have enabled him to point to the circles being formed by the impact of a body of fast-spinning air that has been partially ionized. He explains how a columnar atmospheric vortex, with a vertical or inclined axis, provides the channel for the formation of a plasma (ionized gas) vortex and for its conduction towards the ground. The ionisation of the air ought to be sufficient to make the vortex luminous at night and the fast spin may make the vortex appear ball-shaped. Such a description suggests that Meaden may well have explained some sightings previously reported as UFOs in areas where circles have been found."

Weather patterns from North America to Australia lurch ponderously in sympathy. El Ninos occur every 4-7 years, suggesting some periodic phenomenon is waving a geophysical baton. The real cause of El Ninos is still obscure. However, the recent discovery of over 1,000 previously unmapped submarine volcanos rising from the seafloor in the eastern Pacific may lead to El Nino's source. The synchronous eruption of, say, 100 of these volcanos might warm the ocean around Easter Island a tad -- just enough to warm the atmosphere above a bit -- resulting in a shift of the high pressure area. The area of intense volcanic activity covers 55,000 square miles of sea floor where the Pacific and Nazca plates are separating. In addition to the active volcanos, many plumes of 800 F water gush from the sea floor in this area. The volcano-El Nino link is, therefore, not so far-fetched.

The outer atmospheres of these planets act like radio lasers, which store radio energy and then release it suddenly when stimulated by weaker solar signals. The earth's laser operates between frequencies of 50 and 600 kilohertz. Its emissions are known as the "auroral kilometric radiation" or AKR. While some of these terrestrial emissions are spontaneous, others are stimulated by Type-III solar radio bursts. The newly discovered Jovian laser operates at hectometric wavelengths and is also triggered by the solar radio bursts.

... of light coming down from the sky to the glowing region. Grass and weeds along the roadside were standing straight up and glowing. Deep-red lines of light were seen dancing on the road. They returned to the car, and it felt hot to the touch! Soon, clouds moved in and the display was over. The authors of this article personally investigated this event within a few days of its occurrence. They found the two witnesses obviously very shaken, but believe that the accounts are fresh and unadulterated. Also pertinent is the fact that a large solar flare had just occurred, and intense auroral displays had been predicted. Also, the two women were apparently the only witnesses of this phenomenon. (Swords, Michael D., and Curtis, Edward G.; "Atmospheric Light Show," Pursuit, 16:116, 1983.) Comment. The article also contains the authors' analysis in some depth. Basically, they thought the phenomenon to be auroral with coincidental rainfall containing organic debris. Reference. Many other low-level auroras are described in GLA4 in Lightning, Auroras.

... March 30th, one of the callers reporting a UFO was a Captain of the national police at Pinson, and [Belgian Air Force] Headquarters decided to make a serious effort to verify the reports. In addition to the visual sightings, two radar installations also saw the UFO. One radar is at Glons, south-east of Brussels, which is part of the NATO defense group, and one at Semmerzake, west of the Capitol, which controls the military and civilian traffic of the entire Belgian territory. The range of the two radars is 300 kilometers, which is more than enough to cover the area where the reports took place...Headquarters determined to do some very precise studies during the next 55 minutes to eliminate the possibility of prosaic explanations for the radar images. Excellent atmospheric conditions prevailed, and there was no possibility of false echoes due to temperature inversions. ". .. at 0005 hours the order was given to the F-16s to take off and find the intruder. The lead pilot concentrated on his radar screen, which at night is his best organ of vision. The F-16 is equipped with very sophisticated equipment, including chase radar, which is not fixed directly ahead of the airplane, but makes a wide search in an arc' of 90 degrees left and right of the nose... "Suddenly the two fighters spotted the intruder on their radar screens, appearing like a little bee dancing on the scope. Using their joy sticks like a video game, the pilots ordered the onboard computers to pursue the target. As ...

... its size, 400 metres across, and it sped northwards. "The Japanese scientists identified the object as a plasma vortex, caused by freak weather. The phenomenon is similar to ball lightning and believed to be generated by 'mini-tornadoes' of electrically-charged air. "Plasma vortices can be luminous at night. 'They are often mistaken for UFOs,' says Dr Terence Meaden, director of the Oxford-based Tornado and Storm Research Organization." (Spicer, Andi; "Clue to mystery of Circles," London Observer, May 20, 1990. Cr. T. Good via L. Farish) Alien Hieroglyphics? "The extraordinary variety of circle formations and multiple-ringed circles is quite unlike what one would expect for a natural phenomenon, such as an atmospheric vortex. The complexity has increased through the 1980s, and this year it has developed at a startling pace. "In May there began to appear what researchers call pictograms. Initially these consisted of two circles joined by a straight channel of flattened corn, with extra features such as rectangles or semicircular rings. There have now been about 20 of these. The latest have quadrupled the length to about 150 yards and consist of complex arrangements of up to nine plain or ringed circles with new features, like 'keys,' which can be seen in photographs of the Alton Barnes pictogram. Nothing like this was observed in previous years." (Wingfield, George; "Ever-Increasing Circles of Bewilderment," London Independent, August 4, 1990. Cr. T. Good via ...
