Researchers confirm first 'fire tornado'

12 posts in this topic

Canberra researchers say they have confirmed the first case of a fire tornado from analysis of evidence collected during the January 2003 Canberra fires.

"The various data were combined and analysed to provide information on the occurrence and behaviour of the phenomenon known as pyro-tornadogenesis," Mr McRae said.

"Researchers had speculated about the ability of a fire to produce a tornado, but this is the first documentation of the creation of a true tornado by the convection column of a large fire," he said.

Really glad we don't get that type of tornado here in Oklahoma... The regular F5 type is quite exciting enough ...

Sorry, but....

The phenomenon is also called a fire whirl and has been known to fire service personnal for decades. It's in the USFS fire behavior manuals. And we do get them in Oklahoma.

I fought forest fires in British Columbia for 9 years. They're very well known. But, I guess if there isn't a scientist around to verify it, it never happened?

Edit: Oh. From the article;

[The research team also showed how a fire tornado is fundamentally different from a fire whirl, which is commonly associated with fires.

"Tornadoes are associated with thunderstorms and as such they are anchored to a thundercloud above, and are able to sporadically lift off the ground. Fire whirls, on the other hand, are anchored to the ground and do not require the presence of a thunderstorm," Dr Sharples said.

The study provides more insight into the behaviour of thunderstorms that form over large fires, which is currently the subject of an international research effort.]

Well, I can't say that I've ever fought a fire during a thunderstorm. But the article said that whirls are anchored to the ground, and that's not true. Sometimes they're over the treetops (100 ft. + in the air).

I was being a bit facetious.... I've seen several smaller versions around, especially in forest and range fires...

They probably meant it was previously unknown to THEM.

Fire whirls form when the air is unstable. Cumulus clouds are a warning that violent fire behavior is possible. They also form when updrafts from a fire punch a hole in an inversion layer.

You really can't get more radical then 'fire tornado', except maybe 'shark hurricane' or 'razor typhoon'.

A regular tornado is bad enough. I've heard of these before can't believe they are just now confirming them.

Edit: They said it was an F2 with a base towards 500m in diametre!!

If you live anywhere near Chickasha you are right on the old tornado highway... US 44... Seems like all the storms follow that road...

But on the good side, you are only about 26 miles away from Asgard! (Broxton)....
