Abstract

It is shown that the shape of the fire perimeter is not always a regular line. In flank or down-slope fires, the fire line can assume a zigzag shape with kinks at practically orthogonal angles. These kinks are associated with convection cells that generate local equilibrium conditions. It is hypothesized that this process is an example of a more general natural law governing convective flows.
