Citation?

Mine says different.

Incorrect. A wildfire is named for the size of the fire. and it being uncontrolled.

"a fire that is burning strongly and out of control on an area of grass or bushes in the countryside: "

No mention of wind.

Studies suggest otherwise

"Burning behavior of mixed-convection wind-driven flames under varying freestream conditions"

https://www.sciencedirect.com/science/article/abs/pii/S0379711221000606

"Buoyancy induced convective flows play a very important role in forest fires"

https://link.springer.com/chapter/10.1007/978-94-011-5058-3_17

I guess it depends on your definition of "important".

No, your ref says in the presence of wind.
Wildfire means 'uncontrolled'
Cambridge Advanced Learner's Dictionary (3rd ed.). Cambridge University Press. 2008.
"CIFFC Canadian Wildland Fire Management Glossary" Canadian Interagency Forest Fire Centre.
Obviously wind is the reason for becoming uncontrolled.
Are you saying that a campfire in the bush is a 'bushfire'? A burning wood-heater in a house in a forest is a 'bushfire'?

'Wildfire severity results from a combination of factors such as available fuels, physical setting, and weather.'
"National Wildfire Coordinating Group Fireline Handbook, Appendix B: Fire Behavior" National Wildfire Coordinating Group. April 2006.

No.. a fire does not phuk a tornado.

Complete garbage... as is Jon Stewarts BS ... & yours.

Fires & their effects  are controllable .... tornados & hurricanes are not.

Your white flag would mean SFA.

So convective wind has a different attribute than weather controlled wind?

chimera wrote on Jan 14^th, 2025 at 5:01pm:


Your glossary says -"Fire Storm A large continuous area of intense burning characterized by violent fire-induced convection resulting in gale-force indraft surface winds near and beyond the fire perimeter, a towering convection column, and the occurrence of large fire whirls."

I guess convection is a problem after all.

"A wildfire--or multiple wildfires in the same area--can cause a firestorm. A firestorm occurs when heat from a wildfire creates its own wind system. This phenomenon can lead to very strange weather effects. "

What part of large, uncontrolled didn't you understand?

See my link above.

And here maybe endeth the first lesson.

Convective wind is vertical. Different from horizontal which is not vertical. Uncontrolled means not a fire as normally used which is unaffected by weather and is controlled, as in a house stove.  Weather includes wind. The wildfire changes from controlled fire because of wind. The sites say its the wind. For wildfires. Convective wind is verti

'Can spread' is not describing a horizontal wind. Cooling convection is also vertical, outside the rising convection and is to the side. You knew that.

All my plumes have mass and possums eat them. They fall vertically and a bit to the side, not far unless the wind blows. Fast winds go faster than slow winds. Unless the slow ones speed up. Sideways, except for downhill. Or uphill. Or both. It's not windy now. It was but it stopped. The wind may start again, very likely and almost certainly.
