The Transition and Spread of a Chaparral Crown Fire: Insights from Laboratory Scale Wind Tunnel Experiments

Figure 6

Rate of spread behavior in (a) surface fires and (b) crown fires. Rate of spread in nonwind-driven fires (left columns), wind-driven fires (right columns), and a box and whisker plot for the average rate of spread for all experiments (middle). On the box and whisker plot, the black line represents the median and the black “x” represents the mean.
