There is a piece of shareware for the macintosh called 'Triplot'.  It is by:

Gary Carroll
Dept. of Geology
University of Western Australia
Nedlands 6009

It reads tab-delimited text and will plot anything you like on ternary
diagrams.  Options for diagram parameters, markings, legend etc. are built into
the program.  Diagrams can be exported to any graphics program for modification
once the data points are plotted.  I have an old version (2.02 which is dated
1989).  There may be a newer version floating around.

The poster you are flameing here is from the Netherlands and one assumes
that his first language is Dutch.  I wonder how erudite your posting
would be if you were working at the same disadvantage.

Re: The rest of this thread.  This discussion is turning into nothing
more than an exersize in prejudice.  It is mostly generalization and
P+Ming with no thought to how the situation can be helped.  It is
interesting that this blather is being broadcast in a sci.newsgroup.
It would seem that you are doing exactly what you accuse journalists of
doing.  I.E. Writing without the benefit of rigorous thought (the
hallmark of good science.)

As a 40 year old journalism student, indeed I have learned from the
poor science reporting that is out there but, ironically, I have learned
very little here that would help.  I hope that when I enter the workforce
I will not paint with as broad a brush as you.

I suppose it IS easier to talk about the weather than do anything about it,
but I am saddened that my posting on a possible solution (see Proposal for 
News Awareness) has met with stony silence.  Was it such a bad idea or is
it just because I mentioned my connection with journalism and am therefore
a pariah?

The most effective piece of earthquake prediction was done by the mass
mobilization of the Chinese population in the Luaoning province. They 
monitered everything from well levels by school children to animal
behaviour by owners. Seismologists of course did the technical bit. Very
few people were killed by this earthquake despite it being magnitude 7.4.
Personally, I'm not in the prediction business and it working one time in
many thousands is not very satisfactory. At least it will keep the US Mail

while for the most part, lightning tends to strike the ground in
the area directly below the cell, often c-g strikes originate in
the upper part of the cloud, and tend to land well outside the
actual storm.  these are the ones that set fear into the hearts
of the b.l.m. and forrest service meteorologists, as they tend to
start fires.

your itchy feeling was the electrostatic charge building up around
you just prior to the strike.  if you would have looked at the hair

Finally our news server is working again, so I can post this!

I like what Michael Tobis has been posting on the climate change problem, but
this one unrelated element of his post needs some comment (sorry Michael, I
hate to nitpick, but I have to in this case because the topic is widely
talked about and the terminology has to be clarified):

El Nino describes a phenomenon in the OCEAN.
Southern Oscillation describes a phenomenon in the ATMOSPHERE.
ENSO describes a COUPLED phenomenon.

The Southern Oscillation tends to be associated with global weather pattern
anomolies (which vary considerably according to just how strong the SO is
and just how far E or W it is). We see these most pronounced in ENSO events
because the warm waters farther east support convection extending farther
east in the Pacific, giving tropical heating distributions which cannot
otherwise occur.

El Nino can occur without the SO coupling, as happened in the winter of
1990-1991-- the waters were very warm in the equatorial Pacific (I don't recall
if the classic warming along the S American coast occurred, but the more
meteorologically significant warming near and somewhat east of the dateline
was large in magnitude). However, the circulation patterns were not like
those expected from ENSO and the convective anomolies inferred from outgoing
longwave radiation and from divergence in the upper tropospheric wind field 
also indicated an ENSO event was not occurring.

Summary: A rather poor attempt at a definition
Date: 23 Jul 92 14:38:51 GMT
Distribution: na
Organization: University of Oklahoma, Norman, OK

Several people have sent me mail asking just what exactly is a gustnado, so,
not seeing Greg Stumpf anywhere in sight, I thought I'd go ahead and offer
a definition/my best understanding of what a gustnado is...

Gustnadoes form on the leading edge of thunderstorms, where the outflow
boundary/gustfront is located.  Now if you have a dust devil or some
similar broad low power circulation ahead of the gust front, the interaction
of the front with the circulation stretches the vortex and narrows the 
diameter.  Since energy must be conserved, the angular velocity is forced
to increase (spinning figure skater bringing her arms close to the body).
This is the basic form of the gustnado.  They don't normally have winds
in excess of F0, and don't derive their energy in the same manner as a
tornado, and since the circulation is not pendant to the base of the storm,
it is not a tornado (by definition).  The only way they are visible from 
the dirt raised by the winds.

A good example of a gustnado that a lot of people have seen is from the old
Nova episode years ago, where Lou Wicker is screaming "That is the wierdest
thing I've ever seen!!!" in reference to what appeared to be a tornado
hanging down from the front end of a thunderstorm.  If you listen to the 
details he describes, it becomes obvious they are looking at a gustnado...

Yo, Greg!  Bail me out here if any of this is wrong...

we had a thunderstorm blow through southern indiana yesterday afternoon;
actually it was early evening, 6:00-6:30 local time;.  the sun was to
the west backlighting the cloud.  as the cloud moved east and the sun set
lower in the sky it begain to highlight (lowlight) the lower portions on 
the thunderstorm.

i noticed the orangish (someone might have called it yellow) highlights 
before the sun actually appeared below the thunderstorm.  the orangish
tint comes from the blue light being scattered leaving red & green
to produce yellow/orange; (this is the same reasons the sky is blue & 
sunsets are red).

You describe classic symptoms of either migraine headaches or of
untreated glaucoma. I have suffered from both and would describe 
what I saw exactly as you have. This would explain why some people 
see it and some don't! Glaucoma is the more sinister possibility, 
because if it goes untreated it will probably result in blindness, 
over timescales that range from years down to hours depending on 
the severity. See your ophthalmologist while you still can.

Location of lightning is done by radio direction finding.  Several
stations are required to receive the burst of "static".  I don't
know frequency present systems operate on, but 9kHz has been used.
By triangulation, the location of the strike can be determined over
a range of about 2000km.  Obviously, the accuracy will be dependent
on the number of receiving stations, and the range.

The fixes are referred to as "sferics" (from "atmospherics").
 
In New Zealand, we don't have this equipment, but some of our
AWS (Automatic Weather Stations) have a very simple VLF receiver,
with a whip antenna.  When lightning is nearby, the bursts of
radio static are picked up, and increment a counter.  The counts
are sent back every hour with the rest of the weather information.
It's crude, but does give a reasonable indication of the area's
"activity".

Of course both systems will pick up any lightning, not just that
that hits the ground.
