Winds gusting to hurricane force?

[Michael]

If people are upset over what a tornado here can be.how about just a land spout/water spout(this one is used over water).
I know far more annoying words / phrases than these weather terms mentioned on here.

[Manukau heads obs]

note that the met service use gusting to a BFT speed themselves (in the weather warnings)
i,e

The strong winds are expected to be between 6am and
1pm Sunday, with possible severe gale gusts of 130 km/h in exposed
places.

Maybe it's time to use the Beaufort scale as in the UK, ie: "gusting to force 6"

Yes I noticed that - which is why I thought what we were doing was ok. In the future maybe we'll say "for a time" rather than "gusts".

And I mentioned torandos today...I didn't say mini, weak or small. I hope no one thinks the movie Twister is about to develop over NZ.

[NZstorm]

130km/h is 70knots. A severe gale is around 45kts average. Maybe they were meaning a severe gale gusting to 70kts. Generaly you would need a mean wind around 45kts to achieve 70kt gusts.

[Manukau heads obs]

good point!
I missed that...
I think you are right, thats what they meant

[Nev]

... Maybe they were meaning a severe gale gusting to 70kts. ...

That's what they should, and normally would, have said. Methinks somebody stuffed-up

And I hope that every time someone sees a sheet of airborne roofing-iron they don't say "must be a min-tornado"...

P.S. It's spelt 'tornadoes' (not the first time Phil)

[Philip Duncan]

I don't know if they made a mistake - I've seen them write that many times before.

[Philip Duncan]

And I hope that every time someone sees a sheet of airborne roofing-iron they don't say "must be a min-tornado"...

I agree...in fact it's almost becoming a kiwi-ism... squalls are now being called mini-tornados all the time. A mixture of the public calling them that and the media simply quoting them I would say. I think it's a term that will be with us for a very long time as it appears it's now evolved into the every day language of the public.

Just this last week I saw on stuff.co.nz that the iron being ripped off the roofs on the coast was blamed on 'mini-tornadoes'. It seems to me that on occasions when ever there is damage from winds the media hypes it up into a mini-tornado. There was even video to prove they werent a tornado but still they say that!

[Philip Duncan]

Yep I agree.

Was interested when out this morning to see plants in a garden (roadside plantings) that looked as if just one branch had been twisted right around and out of the centre of the plant. Maybe some strong gusts have a twisting motion of their own that does not move on to another place? Two different plants (but close to each other) and the branches had been dropped back onto the plant and nothing else appeared damaged??

[Manukau heads obs]

was there buildings nearby?

MumCarrot. Nice name

Gardens were on the verges of an industrial type area - but no very tall buildings - and they were still a distance from the plants in question. I was intrigued because they were not the biggest plants around.

There is a reason behind it - which concerns another "carrot" internet persona - and I am his mother (or was, we lost him

Misquoted ???

From this morning's 'Sunday News'...

'Third storm rages on while crews clean up'
Sunday, 03 August 2008 - By KRISTIAN SOUTH

Clean-up crews were last night frantically battling the weather as the third storm in less than two weeks rocked New Zealand. ...

Metservice spokesman Bob McDavitt said while this weekend's storm was likely to create further surface flooding and slips to already affected areas, they were not predicting a repeat of the widespread havoc of the previous two weather bombs. ...

MetService severe-weather forecaster Andy Downs said the latest weather bomb was moving faster than the system that brought last week's flooding and slips. ...

[Philip Duncan]

That's a shocking misquote!

My quote in the Herald on Sunday was taken yesterday - but looks as though it was for today! Just one of those things.

[Nev]

I take it you mean this article 'Owners leave homes as wild weather hits' ?

Seems to be standard practice, with 'Stuff' perhaps being the worst offender.
Perhaps MetService should write a strong letter to Stuff, clearly explain exactly what a 'weather bomb' is and suggest the term shouldn't be used flippantly?

Bomb was on the 26th. Here's how rife the practice actually is (last one's marginal) ...

One of the problems with “weather bomb” is that it is a poor choice for a technical term. It looks and sounds colloquial and non-specific (unlike, say, neutron bomb or water bomb).

Perhaps it could have been called “air pressure bomb” or somesuch and inexperienced people would be less likely to misuse it.

Better still would have been the avoidance of the use of “bomb” completely (which the Oxford defines as “a container with explosive, incendiary material, smoke, or gas etc., designed to explode on impact or by means of a time-mechanism or remote-control device.”

Whoever dreamt up the name was misguided if they thought it would suit as a technical term. It belongs with “polar rodent” and other such vividly descriptive (but inexact) terms.

[Nev]

Yes, fair comment and I have to say I reluctantly agree with you.

I also wonder how many hits the Waihopai spy-dish picks up

Maybe all the other depressions should be called 'mini-weather-bombs' ...

[03Stormchaser]

Just this morning I woke to an unforecasted 'drizzle-bomb'!

that will soon be in wikipidiea, just wait! (LOL)

Weather bomb is not a technical term. I've never come across it in the literature at all (thats not to say its not there, just that I have never seen it). The correct technical term is "bomb low" which has a particular and precise technical meaning (which I'm sure we are all aware of). I have read the original paper which introduced the term "bomb low" and from memory I think the phrase was chosen because of the "explosive" cyclogenesis in such systems. Thats why I changed the title of the recent thread about the latest storm from "weather bomb" to "bomb low".

The term weather bomb originated a few years ago as a misquote of Bob McDavitt (I think, might have been someone else) who did an interview in which he correctly described a rapidly deepening low as a "bomb low". This was initially reported verbatim by the media. However, subsequent media reports started talking about a "weather bomb" and its gone on from there. Its a total media invention.

IMHO "weather bomb" i s as annoyingly inaccurate and unacceptable as "mini tornado" or "gusts to hurricane force", and shouldn't be used by weather professionals.
