Conditions for Plume Dominated Fire. Observations in the Hungry Horse Reservoir area on Thursday, September 04, 2003, revealed that as the inversion started to clear out about 3pm, the response of the Blackfoot Lake Fires and Wounded Animal Fires was almost instantaneous.
Types of Plume Dominated Fires. There are two general types of plume dominated fires: 1. A plume dominated fire in heavy fuels can make a fast uphill run. This situation occurred on the Butte Fire in the Wallace Creek drainage in 1985 when the fire suddenly ran uphill and trapped 73 firefighters in fire shelters on the ridgeline for, Firestorm: how bushfires create their own weather – CFA …

10/13/2019 · Hilly terrain, lots of dry fuel, heat and instability in the air contribute to the creation of these updrafts (also called plume-dominated fire). If the pyro cumulus cloud becomes large enough, it then starts to generate its own localised weather, including lightning (called pyrocumulonimbus – a thunderstorm created by a bushfire).
A plume-dominated fire exhibits the increased role of the convective force generated by the heating of the fire. The fire itself begins to influence the wind field around it. This added vertical development has also been described as fire in the third dimension along with the length, width and atmosphere above and around the fire .
8/14/2020 · In Wednesday’s case, the fire went plume-dominated in rugged terrain marked by steep canyons that funneled the winds and accelerated the fire’s movement even more.
11/20/2020 · In a nutshell, the fire will remain plume-dominated as long as the heat being released from the fire is warmer than the air surrounding it as it rises.
10/21/2019 · Often, before a bushfire creates its own weather, it becomes plume-dominated – where the energy in a rising convection column is more powerful than the wind near ground level driving the fire . It doesn’t take much for this to occur it doesn’t even require a big fire .

Plume-dominated fires – Fires with well-developed convection columns whose spread is normally characterized by pulsing, usually in all directions. Prescribed fire/burn – A natural or human-ignited fire burning under a strict set of predetermined conditions to fulfill …
