Morning Terry and Alan - thanks for responding.
I have an old computer which was an IBM clone and has been built up a
couple of times. It has a 486 CPU and used Windows 3.1 (DOS). The
MAil program is the freebie Microsoft Internet MAil, version 3.02a.
y daughter has a brand new computer and tells me she gets this same
message on many of her mails. ???
The message says
"Can not find a conversion for 'application/ms-tnef' MIME body part.
It will be treated as binary '.BIN' data. It may not be possible to
view or use this data without further processing."
The attachment, when I click on it, is labelled ATTACH.BIN
When I save it to a disk it exists as ATTACH.BIN, but is not avaiable
to open.
I used to get this just on mails from Truffles, and always on mails
from Truffles, and I just clicked OK on the message, ignoring it.
But when it appeared on mails from Jane and Dane, I got a little
concerned. Hence my message.
The Logo message from Jane has .GIF filenames, and I have been unable
to access these in the past - may be due to my lack of knowledge,
advice would be welcome on accessing these.
And finally - my c: drive does not have much spare memory - I'm trying
to buy more RAM but 486 RAM seems not easy to buy. So I always insert
a floppy and save to a: drive.
I hope this information is sufficient for you to make a diagnosis.
Don't want to shoot the beast yet - It has made retirement bearable.
Cheers,
Nandina

"MIME" refers to how the mail message was put together (MIME format or
encoding). The 'application/ms-tnef' is one such body part that your
Email client can't make head or tail of. See the following for an
explanation of what this part is. I'll extract text from a previous
Email...
--- Included text from Michael Scollay mail dated 21/01/1999 16:58 ---
More info: I asked one of our resident mail experts about this. He
reckons that this TNEF ( Encoding Format) attachment is a
MicroSoft thingy that concerns the positioning and encoding of
attachments and other encoded parts in the mail. So if you turn off
"Rich Text Encoding" capability etc., then you'll send only plain text
from MicroSoft Email clients, notably Internet Explorer, Outlook etc.
Wullah. I think "sending only plain text" is what we agreed to
in-the-beginning. The trouble is finding out how to ensure this from
the myriad of Email clients available:-(
--- End included text ---
As far as Nandina is concerned, you do nothing (yet). People who are
sending such mail need to look at the setup of Internet Explorer
and/or their mail client. There is a button or option that does
something like this i.e "turn off rich text encoding". Look also at
configuration files in C:/WINDOWS such as those labled with ".INI".
Removal of any fancy mail client text formatting will suppress the
sending of this particular attachment.
> The attachment, when I click on it, is labelled ATTACH.BIN

That's a typical Microsoft programming decision tree that goes
like..."If I can't decode the attachment 'application/ms-tnef' then
convert it to text and call an executable with the prefix of the first
text I decode"...which happens to be "ATTACH" because
'application/ms-tnef' is likely to contain this word "ATTACH" because
this attachment is supposed to describe how to position and format the
mail text on compatible email clients. I know that sounds dumb, but it
happens to be true. If you look at the majority of Microsoft
application files, right inside is a reference to the version of
application that created it. If the extension sheds no light e.g.
.DOC, .XLS etc. then the application will try to read the file. This
is why it trys to find "ATTACH.BIN".
Nandina, 'application/ms-tnef' is nothing the click on or worry about.
It's just annoying and that's Microsoft through and through:-)

Now this is something to be concerned about, Nandina. GIF images are
basically fundamental to the internet. Normally, Internet Explorer
should be able to decode gif images. Maybe the gif image in question
is of a format that your version of Internet Explorer can't decode.
Alternatively, save the attachment from your email client and open it
in some other gif reader. Don't ask me what else exists for your PC
since it ought to be supported through Internet Explorer.
Without a direct reference to the image in question, I can't vouch for
it's format. My gut feel says that you are looking at an upgrade for
Internet Explorer as well. Why not try a move to NetScape instead?
It's free, but you'll need more disk for this, however.

I'm not sure what you're saying here. Insufficient disk space and not
enough RAM are two largely separate issues except when you deal with
Windows Virtual Memory (WVM). You need enough spare C: drive for the
WVM to allocate and use. What Windows does is shove currently unused
applications that were loaded into RAM into VM temporarily. When you
want that application back to use, the WVM swaps it back into RAM
after pushing something else into VM. This can be -very- slow if you
have a slow hard disk, not to mention that brain-dead DOS file system.
So the usual solution is to add more RAM. There are thousands of old
machines that could be raided for 486 memory. Check with some of the
PC-lease companies that deal with Telstra for example. You'll need
someone with some knowledge about how to do this though. 16MB is
considered a minimum for reasonable application performance with DOS
6.22 and Windows 3.1. Many systems run with 8MB, but that's pushing
your luck a bit. You'll need about 50MB free disk space for WVM. I
have found in old practice that Windows starts to die when about 30MB
of VM is being used because it can't swap fast enough between the RAM
and the VM on disk.
As for disk space, there must be thousands of old drives out there
that you could buy for a song (see above). All you need is a few
hundred MB as a D: drive to put all your data files on and leave your
C: drive for the operating system and applications. I take it that
your C: drive is rather small. The objective here is to get as much C:
drive free as possible for the WVM to operate acceptably.
Now if it were me, I'd get enough disk to load Red Hat Linux with 16MB
RAM min, trash DOS/Windows and load up Netscape V4.5 for Linux:-)

Good luck!

Hi all,
Well...our atmosphere is reasonably unstable (and has the potential to
become further unstable upon close inspection of a very borderline
Skew-T) but it's very cool, almost cold here in Brisbane. I'm currently
sitting on 25.4C, the Brisbane obs are 24C with a DP of 19C and SSE

There are some t'storms about 200km SW of us, and further t'storms about
350km W of us, but it's not looking that great now. I'm still hopeful,
but these cool to cold temperatures are killing us!

we need to get up to 27-28C at least before we can have any decent
chance though.

While eastern Australia has had a rather warm summer for the most
part, it's been a notably cool one in the Pilbara, by their standards
(which are still pretty hot).
With 2 1/2 days to go in February, Marble Bar's mean maximum for the
months is sitting on 34.6 (previous record 34.9, 1995), 5.4 degrees
below average. It has failed to exceed 40 once in the month (assuming
it doesn't before Sunday, this would be the first instance in any
month between November and February).
Measureable rain also fell on 21 of the 23 days 2-24 February, including
runs of 11 and 9 consecutively. The monthly total is 282 mm - well
above the mean monthly total of 83mm (and not too far short of the
mean annual total of 346), but not a record.

Hi Chriss and to all who may be interested;
The information is from: http://www-das.uwyo.edu/upperair/au.html
For the text data, click on 'text' first, and then click on the closest
location near you. For example, Brisbane is "YBBN" and Sydney is
"YSSY," and that will give you the atmospheric soundings. The gif
format is the Skew-T, it's even more useful then the text info, but
somewhat harder to understand. It's possible to extrapolate expected
atmospheric changes from the Skew-T which makes it a very useful tool.

(Michael Scollay here:) Me too. But I am a Sydney-sider also:-)
My worst day for wind chill was July ??, 1981 at Thredbo. The temp on
top of Crackenback (2037m) was -18C with a wind speed of 85kph. That's
one hell of a wind chill factor!
Another occasion was in Utah, USA sometime during late January, 1984.
This occasion set a record for Utah while I was skiing at Park City.
We stayed indoors as the temp went down to -65F (-54C) somewhere else
in Utah at about 5am. By 7am, Park City had warmed up to -50F (-46C).
I went outside and puffed in this artic air. The vapour from my breath
formed ice crystals almost instantly. My private snowstorm of sorts:-)
The ski lifts were open when the temp rose above -40F (-40C). That was
about 10:30am. By midday, my girlfriend, Kym (now wife) and I were
using our stocks to drive ourselves down black runs with the temp
around -35F (-37C). There seemed no skid whatsoever in the snow.
Beautifully shaped ice crystals filled the air at times seemingly
forming from nowhere. These entered our lungs unmelted to make us
cough. It was like breathing a type of dust. Throughout the whole day,
there was hardly a breath of wind. Next day started comparatively warm
at -30F (-34C).
What felt colder you ask? We were dressed in the same ski clothes too.
Well, it was lucky that we couldn't ski fast in Utah since we almost
certainly would have frozen any bare skin. That did happen to Kym's
nose, the only bit that stuck outside in one particular run because
she forgot to tuck it in after blowing it. I'd have to say that
Thredbo during that bitterly cold and windy morning is welded in my
mind since that wind found every possible crack in my clothing
chilling me to the bone as we rode that chairlift.

The city site is still waiting for its first 40 for the summer, but we've
had a few 38's and 39's, thats when the airport prolly got up to 40 on one
of those days, last summer we equalled our record with 6 days over 40 for
the city site, even though the old city sites are not directly comparable,
but unlike our winter minimums, I've noticed our daytime maximums are very
similar to the old city sites since it got moved to the inner suburb of
Mount Lawley in November, 1993.
Hottest I've seen the city temp get up to so far today was 37.1C, the
airport 37.2C.
Right now at 1:55pm, the city is at 37.0 with a light NE wind, airport
37.2, Swanbourne Beach 36.0 which is now in a SW, and even Rottnest Island
is sitting on 36.0C and surprisingly still in a NNE wind at 17km/h.
So that means for the city and we've had 4 days over 35C, and 3 days in a
row over 37C, 36 is forecast for tomorrow.

While it might not seem anything particularly special to those
from more northern climes, today was the 50th consecutive day on
which it has reached 20 degrees at Melbourne.
This is the 8th such instance in 144 years of records, most recently
in 1983 (57 days: 25 January-22 March).
The record number of consecutive days over 20 is 70: 26 January-4
April 1956.
Current models suggest that a sub-20 day is unlikely on any of the next
seven days, which would be enough to hoist 1999 to equal third on
this list. We'd need to last until March 19 to break the record.

Between you and a friend of mine who has just headed off for some skiing
in Canada - I'm getting REAL itchy for the snow season.
I cannot believe how bad last seasons was. 1997 was bad - and we all
thought that 1998 would make up for it. What a disappointment!
Anyone want to make some brave predictions about this years season? :)

Hi ,
i have been in contact with my mother who lives in the Swan Hill district
and she gave me a bit of an idea how big the particular storm was on the 28
of January 1999.
She lives in Woorineen.
Her Air conditioner which is on her roof was struck by lightning
and caught fire.....one of those big box looking things.The top of it was
blown off and all the sides had peeled off.She went running through the
house trying to find out what was on fire ...two foot of smoke by this time
was in the house...Found out it was the air con ...thankfully the fire
didn't take hold and must have burnt itself out in the roof ...maybe even
put out with the rain after she turned the power off to it.She still had a
very sleepless night none the less.
The next day she found out that someone had lost their roof........A
caravan had been found on top of a packing shed......and 3 cows were killed
as a result of flying tin.One of the wildest storms she said she had been
through.
As they were driving into town she said the side of the road looked
unbelievable as all the shrubs and the tea trees had been stripped of all
their leaves and they looked ...what she only described to me .....ripped
shredded and mangled.
So that one sounded like it was a doozie for sure..
Manda......

No way. My tried and proven "theories" got dumped in the garbage bin
after last years snow, or lack thereof:-( Mind you, the week that I
skied was one to remember with some 90cm of snow falling in the three
days from Aug 15 to 17 inclusive. The difference in this fall was that
it came from the E-SE direction around the top of a high pressure
system! There was a decent low in the Tasman that pumped a deluge onto
the Illawarra region but it stayed just cold enough (-4C to -1C)
during that time to dump a load of snow in Perisher Valley. So much
snow that many trees collapsed...

Yep - went boarding the day after those dumps - woohoo!
Still - I guess we can be thankful we don't have the conditions
in Austria and Italy at the moment. The death toll seems to be
rising daily. Still - the story about the boy who was clinically
dead for 2 hrs - and then revived - was pretty amazing.

I skied the same week (actually.. I thought it was earlier in August
but I remember there being a 'massive' 24 hour dump [tuesday??] and
healthy falls on the flanking days a few days ending the day we
arrived) and it was fantastic. I think I have been fortunate in that
on several occasions I have skied 'poor' seasons at prime times and
had a great time. On the other hand I have headed down there on
otherwise 'good' seasons only to be greeted with drizzle/rain and/or
sleet and/or very high winds. So I guess rather than looking for a
good season I sellfishly hope for a good week early this coming August.
As for predictions I usually go with probability, the same as I do for
the storm chase season; after several poor snow years the next has to
be a good one - it eventually works, perhaps this year:)

Can anyone tell me how to calculate return periods of weather events (as
in 'it was a 1 in 500 year flood' etc)..in my case I want to know how to
do this for extreme temperatures and rainfall.

Just found an article on the outflow gravity current in a thunderstorm at
Sydney airport. Thunderstorm-generated gravity currents are not always
visible and this makes for pretty interesting reading.
A thunderstorm outflow current visualized by bushfire smoke.
