Cover Story: Wildfire behavior is governed by complex interactions among several physical phenomena, such as wind flow and turbulence, heat transfer, aerodynamic fuel drag, and combustion. In this study, the role of buoyant flame dynamics, vorticity-driven motions, and instabilities in dictating wildfire propagation is investigated, using simulations conducted by a physics-based wildfire model called FIRETEC. It is found that the flame-front is organized in a series of fingerlike coherent structures called ‘Towers’ and ‘Troughs’. The characteristics of wildfire–atmosphere interaction associated with these structures are then identified to establish quantitative baselines, against which future experiments can be benchmarked.
