Extreme fire behaviour and a case study of the 2016 Waroona fire in Western Australia were explored during a recent webinar hosted by AFAC’s Predictive Services (Bushfire) Practitioners Network.
The webinar, which is available below, featured Mika Peace from the Bureau of Meteorology, discussing the lessons learned from the Waroona bushfire. The audience included Fire Behaviour Analysts (FBANs), researchers and operational practitioners from fire and emergency services across Australia.
The Waroona fire burnt over 68,000 ha and destroyed more than 160 homes in south west Western Australia in January 2016. During the first two days of the fire, there were four episodes of extreme fire behaviour. The processes that occurred at the Waroona fire were driven by three dimensional fire-atmosphere interactions.
The case study uses a coupled fire-atmosphere model, and the Australian Community Climate and Earth-System Simulator (ACCESS) Numerical Weather Prediction model coupled to a fire spread prediction model to describe key features of the extreme fire behaviour of the Waroona fire. It also introduces the coupled fire-atmosphere model ACCESS-Fire and reports on progress simulating the Waroona event with the coupled model.
The Predictive Services (Bushfire) Practitioners Network are also hosting another webinar on 13 December, ‘Aussie FBANs in Canada’. For more details visit the events page.
For more information on the case study see the conference paper from AFAC17 powered by INTERSCHUTZ, or check out the paper published in the Journal of Southern Hemisphere Earth Systems Science.
