Fire size distributions calculated for varying growth and suppression rates.

<p>Results are based on simulation runs for a fire in a region containing burnable substrate of parcels. In (A), growth rate varies in the absence of suppression. Dangerous conditions are described by a pure power law with exponent . Extreme conditions lead to excess weight in the tail, which can be interpreted as fires that have surpassed a threshold value and can no longer be controlled. Finally, mild conditions result in a sharp (exponential) cutoff , which decreases as decreases. In (B), the suppression rate varies in dangerous conditions . Pure power laws are obtained for a range of , with an increasing exponent (steepening slopes) as suppression is increased.
