... overlapping patterns." "At this point the vessel was surrounded by the phenomenon to a distance of approximately 1 n. mile radius. Yet again the patterns changed, this time to parallel concentric circles moving outwards from numerous centres. The display started to decrease at 1725, returning to milky-white patches before eventually disappearing at 1730." (Watson, M.M .; "Bioluminescence," Marine Observer, 65:59, 1995.) Bioluminescent displays often possess mixed geometries. In this illustration, both moving bars and rotating spoked wheels are noted. Location: East Indian Archipelago. Time: 1959. May 23, 1994. Equatorial Atlantic. Aboard the m.v . Taunton enroute to Richards Bay. "At 0550 UTC the vessel was passing through an area of thunderstorms with moderate to heavy rain and the nearest area of lightning was about 4 n. mile away when the Chief Officer went onto the bridge to observe some bioluminescence. At this point he noted that the hairs of his arms and moustache were glowing with a bluish light although no tingling or any other sensation was felt. A check of the vessel's aerials revealed no traces of 'St Elmo's fire' and the observer seemed to be the only object affected. The glow disappeared once he retreated to the wheelhouse but reformed when he went outside again but without the same intensity." "What was noticeable was that the bioluminescence was only seen at the same times as the St. Elmo's fire, and the observer was left wondering whether it appeared in response to ...

Borrows recounted a pertinent incident involving horses and lightning: "I was driving from Aylesbury to High Wycombe via Hampden during a thunderstorm. On an open hillside to the north of the valley, two horses were quietly grazing when suddenly, for no obvious reason, they bolted to the far end of the field. Within about 15 seconds of them moving, there was a lightning strike at the point where they had been standing. How interesting to reflect that more modern means of transport may also be able to detect the highly charged atmospheric state, but appear to be immobilised rather than spurred to self-preservation."

Science Frontiers ONLINE No. 100: Jul-Aug 1995 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects How can the moon affect the earth's temperature?Several weather phenomena, such as precipitation and thunderstorm frequency, have been linked to the phase of the moon. Now, it seems that the moon's "cold" emanations can also raise the earth's temperature. Explaining how the moon's phase can have any warming effect at all on the earth's atmosphere is difficult, because the infrared energy received from the moon is only 10-5 that in sunlight. Nevertheless, a slight but statistically significant temperature effect does exist. In one study, the microwave emission of molecular oxygen was measured by a polar-orbit satellite. These data gave meteorologists the temperatures of the lowest 6 kilometers of the atmosphere from all areas of the planet. The temperature difference between full moon and new moon was only 0.02 C, with the full-moon temperature being the higher. (Ref. 1) A second study took actual surface temperatures measured at noon GMT each day at 51,200 locations around the world. These near-surface temperatures revealed a difference of 0.2 C between full and new moons -- ten times larger than that from the satellite study. (Ref. 2) 0.2 C and even 0.02 C are much too large to be attributed to direct lunar "heating." Instead, geophysicists wonder if the moon's orbit modulates the influx ...

The printout was submitted to Science Frontiers by Mike Epstein. "We were in the deep French countryside a few weeks ago, and during our stay, we had two spectacular thunderstorms. One lasting three hours and one lasting six hours. "One of the attributes of this particular area (halfway between Cahors and Agen) is the dark night skies -- right down to the horizon (I saw constellations low in the southern sky that I'd only seen on star charts). "On the occasion of the six-hour storm (which started about eight thirty in the evening), whenever the rain abated, we went outside and watched. "During a total of approximately 1 hour of watching, I observed phenomena I had never (consciously) seen before. Following ground strikes (probably over the horizon), on at least eight occasions, the ground end of the strike (i .e ., on the horizon) would be glowing for anything up to thirty seconds. "On one particular occasion, my brother was recording the proceedings with a camcorder. I saw a big ground strike followed by a glow on the horizon. I was trying to direct him to that spot, when there was another ground strike 5-10 degrees to the right of the glow; then, maybe a second ...

... bar to act as witnesses. .. .. . "These sky-lines were quite characteristic. There were a least half-adozen in the air, apparently starting close to the ground and fading away twenty or thirty feet up. They were all inclined slightly to the vertical, were of a dirty-brown colour, slightly blurred, roughly four inches wide, several feet apart, of some depth. This was apparent when I walked backwards and forwards across them because they appeared to move towards and also away from me, an event which seemed to indicate that they were slightly curved. If they were more than a hundred or so feet away, they were lost sight of." (Crowder, Robert; "The Strange Case of Angled Lines in the Atmosphere: A Thunderstorm Effect?"

Science Frontiers ONLINE No. 122: Mar-Apr 1999 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Earth Hums More Loudly In The Afternoons It has been known for almost a century that large earthquakes set the earth to ringing like a bell. In SF#118, we reported that the planet also "hums" when there have been no earthquakes. Just what forces stimulate this seismic humming of the earth-as-a -whole is still a matter of conjecture. Actually, "hum" is a poor choice of words. The period of these vibrations ranges from 3 to 8 minutes, which puts them in the range of infrasound. Recently, N. Suda of Nagoya University has found a clue suggesting that thunderstorms may excite these very-lowfrequency vibrations. Suda and his colleagues analyzed the seismic records at four seismically quiet locations around the globe and discovered that the hum is loudest between noon and 8 PM local time. The quietest period is from midnight to 6 AM. These are the same time frames when thunderstorms are most active and quiet. It's circumstantial evidence, but it makes sense. (Kerr, Richard A.; "Earth Seems to Hum along with the Wind," Science, 283:321, 1999.) Comment. Infrasound in the atmosphere may originate from storms thousands of miles away and from strong winds blowing across mountain crests. It appears that the earth is an immense, spherical aeolian harp!
