The core of the system is the WRF-SFIRE model, which is a two-way coupled fire atmosphere
model based on WRF (Skamarock et al. 2005). It provides forecast of the fire spread based on
the local meteorological conditions, taking into account the feedback between the fire and the
3
atmosphere (Mandel et al. 2011). In order to capture the effect of local weather on fuel
characteristics, WRF-SFIRE is also coupled with a fuel moisture model. That allows the model
to forecast the fuel moisture based on the local meteorology (Kochanski et al. 2012). The fire
model is also coupled with WRF-Chem so the smoke emitted from the fire is transported within
the atmosphere, and undergoes chemical reactions resolved by WRF-Chem. The diagram
showing the WRF-SFIRE model components is presented in Figure 1.
