Linking local wildfire dynamics to pyroCb formation — Prof. Jason Sharples

The Fire Centre will be hosting Associate Professor Jason Sharples from the University of New South Wales in Canberra. He will be discussing extreme fire weather and dynamic fire behaviour.

Here’s a recording of the seminar for those of you who missed it:


Pyrocumulonimnbus (pyroCb) events are the most extreme manifestation of a bushfire. They consistently result in loss of life and property, widespread environmental damage and further impact the cultural, economic and political stability of communities. Understanding the drivers that combine to produce pyroCbs is now the focus of sustained research efforts around the globe. Much of this research has concentrated on atmospheric conditions, but given that pyroCbs are actually coupled fire-atmosphere events, it is also important to consider the contributions of the fire itself. In this seminar we consider the role of local wildfire behaviour in pyroCb development. In particular, we highlight the role that dynamic fire propagation plays in driving ‘deep flaming’ events, which appear to be critical in triggering violent pyroconvection. The impacts of local variations in fire weather are also discussed, and the ability to predict extreme wildfire development using operational tools is explored.


Jason is part of the Applied and Industrial Mathematics Group and the Computational Science Initiative. He is currently Lead Chief Investigator on two ARC Discovery Indigenous Projects and Project Leader for the Bushfire and Natural Hazards CRC’s ‘Spot Fire’ Project. These projects all consider various aspects of extreme and dynamic bushfire propagation, the development of large conflagrations and bushfire risk management.
