Spotting can be the dominant fire propagation mechanism during times of extreme fire weather. Spot fires can merge and collapse on one another creating regions of deep flaming, which produce violent pyroconvection. Understanding and modelling the intrinsic dynamics of spot fire coalescence is an important step in providing ways of mitigating the effects of extreme fires.
Predictive models of natural hazards have become a necessity for emergency management, mitigation and adaptation planning.
Junction fires occur when two oblique fire lines intersect with one another. The interaction of the two fire lines means that junction fires can exhibit unexpected fire behaviour, with enhanced rates of spread in the vicinity of the junction point. Quantifying these interactions is essential for the development of next generation fire spread models, which will allow prediction of dynamic fire propagation.
