hrmmm... I'd go at least a rope stage of a tornado.... its more than a funnel cloud anyway imo...
Chris reckons it touched down but just doesnt have any evidence...
Thanks to Michael Bath you can view a loop of the radar here...

even if it is a rope stage and has lifted it is still a funnel cloud. He rekons it touched down, but has no evidence to support it? Takes me back to my last post.. EDIT: Err if I read your post right, tim, thats what you justsaid HAHA oops. Time to hide under a rock again.

I tend to agree with Andy. There could be physical evidence to go by and perhaps the BOM through investigations can confirm this, but unfortunately we only have images. And going by the images at that particular point in time, it looks to be a funnel cloud.

There is a strong possibility that it did touch the ground at a time prior to those images thus "was" a tornado, but we have to assume too many things at this stage. I eagerly await the findings.

Great capture just the same though;)

Whoa, very spirited debate on tornadoes in here.
Quote:
Taken from the Glossary on this site
Tornado
A violently rotating column of air in contact with the ground and extending from the base of a thunderstorm. A condensation funnel does not need to reach to the ground for a tornado to be present; a debris cloud beneath a thunderstorm is all that is needed to confirm the presence of a tornado, even in the total absence of a condensation funnel.
Theres always one player who runs and grabs the rule book!

My opinion is BoM will call it a tornado. it's going to be impossible to go out and find evidence if it were only a brief encounter, barely a F1, the hail prob did more damage.
But, because it was spotted and there is photos, it will probably be declared tornado. by the way, thinking of the glossary last night I checked an ancient news article from 98 or 99,titled '26 Twisters in our own backyard', it had some pics of one at Booleroo Centre, wasnt quite touching the ground and no obvious debris either. Poor quality picture make it difficult. May be the advertiser talking it up, who knows.

Actually, I should put in a disclaimer that my knowledge of meteorology would probably fit on the head of a pin and I do have an extraordinarily oversized mouth. How often do you see this kind of thing come through here anyway? A couple times a year? Feel free to correct me at any point, I am an eager learner and can take a bit of it.

My knowledge of meteorology is very similar to yours Affinity. That is why I looked up the definition on this site so it was clear in my head what we were discussing.

Hi RV

Well, you've educated us both :nerd:

But for such a small tornado, in a fairly open space, it'd be near impossible to investigate. I think they'd take the report on face value and call it. What do you think?

Yes, the Booleroo Centre event was a tornado...

BOM would have access to elements of the doppler radar that we dont... that can help to establish if it was 'likely' or possibly a tornado... I'd imagine an investigation around the area of land where the nader was would also help to confirm.... eg. debris path etc..

Thanks teckert for clarifying the procedures.

So Booleroo was a biggie then.... shocked

AWESOME pics! Is the second one zoomed in, or are you in the very near vicinity?

Interesting to see that the BoM has Adelaide listed as "possible shower" on Tuesday and yet on here, it says we will have "rain developing". I wonder which one will be right...oh and apparently the next week is going to be very very calm, 0km/h winds every day. Mistake, methinks laugh

And by the way Affinity, my weather knowledge is about as much as yours too. This is certainly a good place to pick stuff up!

The second one looks like a frame grab to me of a very close strike. Very nice staccato though and I bet the thunder was loud and crisp.

aussiedeano, The library' s run out of books for me to read, I've run out of doco's to watch! All I have left is to pick the minds of others .

"Jonny 5 need input!"

Is staccato the offshoots of the main strike?Crawlers?

Weather is fine atm, as seems to be the recent trend during the day, apart from the occasional storm skimming its way through the area. About the only highlights of the past couple of weeks have been a brief 10-15 minute lightning storm visible on the W-S horizon at around 1 am (can’t remember which night it was on, but probably in one of the recent BW threads), and a storm moving through the area during the day (I think it must have been yesterday), which resulted in maybe 30 seconds of sparse falls.

If the lightning storm I saw at 1 am had been right overhead, it would’ve really been something – strikes every 5-10 seconds or less, pulsars, flangs, crawlers, CCs, variety plus laugh . But alas, was not to be, will continue to wait with expectations smile …oh, and almost forgot, *rain*!

Wow Corey! is that a faint positive streamer in the front of that second bolt? must have been close! eek

Nice Corey... I think you will find that the second shot has a reflection from the lens itself, it looks like that to me anyway. You can see it is narrow near to the camera and gets wider where the strike over exposed slightly...

This is a reflection I got from one a while back...



It seems to happen with close bolts that are exposed a little too much.

Hello Nazdeck, or curiser as your now called, haven't heard much from ya lately and nice to hear your posts again form Woodside.

NOW FANTASTIC shots corey! First one: Very speccy, nice clarity and the pink bolt and sky with the red sunset is a cracker! laugh

Second one: Geebus that was close, MEATY CG as well, I reckon that was under 1 kilometre away I reckon, and then I would be running for cover in my car. Close lightning is exiting yet dangerous at the same time! Gotta be careful especially if it's dry lightning.

With regards to the tornando, I wonder if we have any doopler archives to show the path and what direction the tornando was going, and as Tim said survey the area for any damage occured form the tornado, so if that is the case, the tornado was well and truly formed and did touch down in those conditions.

Affinity I recommend a website called "anthony cornelius guide to meterology and severe storms" he explains how storms form under our climate and also gives details on the important aspects and terms of storm mechanism and build up etc. I'm still reading it atm and there's lots of facinating info and really a good read for general information! Highly recommended!
