An inconsistency arises in Rothermel's fire spread model when there are two or more categories. If a fuel load is split into identical classes in two separate categories, the reaction intensity is less than if the load is contained in a single class in one category. The author resolves the inconsistency by replacing the weighting parameter for each category with the effective heating number developed from the characteristic surface area-to-volume ratio of each category.
