i need some suggestions on good references as to researching lightning. my copy of martin ulam's work was *borrowed* and not returned... in addition to a new copy, where else can i find good information? (please use reply, if there is enough net interest, i will post the list back to these groups) ....cogent!uop!robert OR .....seismo!lll-crg!ucdavis!uop!robert
robert@uop.UUCP (Robert McCaul) (07/16/87)
in going over some old notes i found some references that might
be of interest:
(i am uncertain as to the obtainability of these)
the lightning research done for G.E. by
Julius Hagenguth
Karl B McEachron
Charles Steinmetz
and in 1962
USAF Lightning research (office of aerospace research)
and in 1961
Donald J Ritchie of Bendix Corp. edited russian papers on Ball Lightning
i hope these minor leads can help someone...
if you know of a place where these papers can be had,
please let me know.
thanks

I am currently doing some research and study of lightning and have come upon the mention of a field mill (a device which measures the intesity of the electromagnetic pulse from lightning) The schematics I have found for one are non-standard as well as archaic. If any one has any schematics of such a device, please send them my way. I am also in search of a way to use a set of radio-directional finders to triangulate upon where lightning strikes are occuring. Any relevant info or comments on this project would be appreciated as well.

While flying in a helicopter I saw a device called a Stormscope which
showed lightning strikes as dots on a display. This made storm fronts
easy to see and hopfully to avoid. It had several different scales, I
remember on being on the order of 250 miles. It operated like a radio
direction finder, according to the pilot. There were several antennae
on the bottom of the helicopter that it used.
Pilots could probably tell you more.
TV stations around the country are installing similar (fixed) devices
for their weather departments. An interesting twist here is that they
collect data, send it to a nationwide center and then presumably
massaged data is given back (sold?) to various TV and radio stations.
Channel 5 near Boston is part of this.
Sorry I don't have more details, these are just my observations. Hope
it helps...

The Stormscope is an old idea, dating back to at least the 1950s. The basic concept is simple; there are two antennas, 90 degrees apart, and you take the intensity of static bursts received on each, treat this as a vector, and plot. There's some way, which escapes me, to tell which quadrant the source is in. Early systems used a long-persistence CRT to display the data; modern systems are digital. Construction articles appeared in various electronics publications in the 1970s. John Nagle
