Fig. 6

A fire behavior nomogram based on predictions from Equations 1 and 4 (Table 1). Right: fireline intensity is predicted as a function of wind speed for four different fuel heights. Left: flame length can be predicted from the estimated fireline intensity—the figure is organized so that the predicted intensity can be read across to predict flame length. Black lines show the predicted values, shaded areas around the lines demarcate the 95% confidence interval of the modeled fireline intensity or flame length. Observed flame lengths and intensities, from experimental managed burns on Calluna-dominated moorland in Scotland between spring 2006 and autumn 2009, are shown as circles.
