Coldies..........winter tornadoes......

Postby bandit » Sun May 18, 2008 8:12 pm

Well the seaon for the coldies is just around the corner so i thought i might kick off a discussion thread about them.

feel free to ask questions, talk about specific tornadic events or say whatever you want!

I'm happy to share what i know & while they harder to chase they are chasable

WA is pretty lucky as we are pretty much the best area for them in the world & we get on average about 8 days per years that have the required conditions to produce them

I'll kick it off with some tech talk, the best paper ever done on coldies is by Barry Hanstrum (formerly of the Perth BOM) it can be found at

http://ams.allenpress.com/perlserv/?req ... -0434(2002)017%3C0705%3ATCSTOC%3E2.0.CO%3B2&ct=1#S6

it's heavy going in some bits but has some interesting points especially when it comes to the shear & cape & what numbers & size of naders they produce. not what you may think.

also how do i post photos on here? i dont see an option for it, if someone twists my arm i might be persuaded to post up some coldie funnels & naders...........

Chasing coldie naders? Sheez that is hardcore. :shock: Try starting a free account on somewhere like photobucket.com, then its just a matter of posting the HTML link I'm pretty sure.

p.s. - that link didn't seem to work for me, would like to give it a read though

nah it's not as hardcore as it sounds, u usually get a chance to see some stuff before the rain gets too crazy & u can't see anymore, plus a drive to rockingham is way cheaper & easier than the wheatbelt & goldfields! now thats hardcore especially with fuel prices today! aahahah


just highlight that whole link & cut & paste the whole line into your browser, i dunno why but it only highlighted half of the link

cheers - that worked. I've noticed on some winter days in the past that coldies can have some fantastic structure. Would love to see some coldie funnel pictures sometime :)

yeah ill see what i can do about a photobucket site, or i can always email them to someone & they can post em up........

but seriously about the rockigham thing, i've found it a way more productive way of seeing them. I still chase summer stuff but im pretty picky these days, it's a mistake most chasers make early on, u go even if it's half a chance. but really for how many summer supercells ive seen ive seen very few naders. winter however is a diff story & i'm hesitant to say how many ive seen for sake of disbelief...

lets just say the hit rate is MUCH better & on the right days i find u pretty much always see something decent. i reckon i see a atleast a funnel or better on every second trip now.............

interesting...chasing even when there's a slight chance has been a specialty of mine lately :oops: but occasionally you get lucky, as I'm sure JJ can vouch for one night recently.

I chase pretty much for lightning, storm structure, and the colours/landscapes (and storms themselves) that you would never see in the city, but geez a nader in summer out in the wheatbelt would be a bonus.

Sounds like you've got the winter nader chasing thing sussed Ira. Again look forward to seeing some photos - oh and if you run out of options and really want to put your photos up, email or pm them to me and you can use my photobucket account.

Well upon looking at the smaller versions I thought mmm thats just an average rain cloud, but looking closer... :shock: there it is in clear view! Huge shame you can't see if it's touching the ground... is it though Ira? Awesome anyways. :D

It touched down in scrubby sand dunes without doing any real damage, an f-0 short lived, just over 5 mins. it went close to houses as u can see, the houses in the shotsback onto bush & without jumpin someones fence i couldnt get behind them. once i had a few shots i did move but its was all over.

i would have liked the full length shot but they happen real fast & dont last that long when they are small like this. u get shots when u can before moving to a better position.

the first few i saw i actually didnt get any photos of becasue i was trying to get to somewhere i could see okay. They move so fast it's not funny, i saw an f-0 waterspout come onto land & go thro a rail yard, across a road in between cars (the cars never even braked) across a paddock and up over a hill like a teenage kid on a dirt bike going full tilt, its was crazy, i never even got the camera out of the bag & it was gone!

I was paddeling from Hillaries back to Mullaloo one Saturday morning last year during a massive storm and saw one small water spout, then an absolutely massive one form about 500-700m off the coast and head up onto land. Thing would have had an easy 50m diameter.

yeah and I'm still kicking myself for missing that one! was about 3 years ago to the day wasn't it? It was a better interview than I got with ABC720, at least they didn't ask you something stupid like "what would I be feeling if I were inside that waterspout Tim", "well Russell you would be wet..." :roll: :lol:
Kia Kaha, stay strong, live long and above all have fun. :)
