Modeling the heat released from a burning wildfire is essential to support coupled atmosphere-fire simulation. This paper presents post-frontal combustion heat modeling in the wildfire spread model of DEVS-FIRE. The developed heat model integrates features from both the BURNUP model and the heat model of WRF-Fire to compute the heat flux of wildfire. To model fuel consumption, it uses the BURNUP model...
We present a methodology to change the state of the Weather Research Forecasting (WRF) model coupled with the fire spread code SFIRE, based on Rothermel's formula and the level set method, and with a fuel moisture model. The fire perimeter in the model changes in response to data while the model is running. However, the atmosphere state takes time to develop in response to the forcing by the heat...
