Hey all. Had a friend over the other night, his brother & girlie work DSE and are doing firework in Gippsland lately, no suprise there. He tells me (via the brother) that a large bushfire can create its own overhead lightening storms? Hot air mass goes up, chit happens, clould forms, lightening stikes in the vicinity.
Any truth to such events? I've never heard of it before.
The story was one of the fronts recently created six seperate spots fires via its own lightening stikes.

G'day Tonester, I heard the same thing on ABC radio the other day.
It surprised me too.
But, I guess with all the thermal imaging and technology available nowdays, they can work out some of these previously unknown things.
If your interested in lightning strike, try this site and hit the 'stormtracker' tab

Not so much lightening, just the fact a bushfire can be a self perpetuating in a new way.

Some of the highest, largest and most active thunderheads ever witnessed have been over volcanoes....
So I guess its possible you could get some lightning in a thunderhead over a bushfire, if its big enough I suppose.
I have heard of this happening but ive never seen it on the tellie or anything..

I've never heard of it but that doesnt mean it's not correct. Lightning is just a buildup of static edlectricity. High temp air rising quickly through cold air...high winds....result is a buildup of static electricity = lightning ...maybe ???
Interesting question.

geez, I'd have to look up old 8yr
geography to try and remember how that stuff work now! Somethings I remember (usually weird stuff) but not that one!

Footy I reckon technically it is possible as the dust an sh particles would create static electricity such as in volcano clouds
HOWEVER I would be surprised if the charge produced by such small scale stuff like a fire (dont forget 1 decent volcanoes ash cloud can effect 1/2 the world in some way) would be sufficient

yes it can.
back in bleep ney with the training, we had some really good video footage of this occuring, and it amazed all in the room, but when you think about Hot air meeting cold air like normally causes a lightening storm...

Pyro Cumulonimbus. Thunderstorm type clouds caused by hot stuff ;-).
If you Google it there is a bit of stuff to read. Or have a look at

You can get the lightning without precipitation especially with dust particles in the fast riseing air column. This gives you 'dry' lightning from the towering cumulus rather then a Cb which has rain (nimbus = rain)

Yes, upwelling hot air loaded with small particles (dust from volcano or fire etc.) causes static charge differance between top and bottom of air column.
