Modelling the Meteorological Forest Fire Niche in Heterogeneous Pyrologic Conditions

open access: yesPLOS ONE, 2015
Fire regimes are strongly related to weather conditions that directly and indirectly influence fire ignition and propagation. Identifying the most important meteorological fire drivers is thus fundamental for daily fire risk forecasting. In this context, several fire weather indices have been developed focussing mainly on fire-related local weather ...
