METEOROLOGY AND FOREST-FIRES - CONDITIONS FOR IGNITION AND CONDITIONSFOR DEVELOPMENT

Following the theoretical model proposed in previous papers in which f our types of days and their associated fire risk (daily fire risk, DFR ) were defined for each size of fire, the authors conclude that the me teorological conditions that favor the generation of fires must be sim ilar to those that are favorable to their development. In a study of b urned areas, comparative results with previous works are obtained, and the parameters DFR and NDFR (normalized DFR) are proven to be in agre ement with their previously assigned physical meaning. The development rather than the ignition of forest fires is better described using th e DFR and NDFR parameters.
