An overview of the coupled atmosphere-wildland fire model WRF-Fire

TL;DR

This paper presents WRF-Fire, a coupled atmosphere-wildfire model integrated into WRF, detailing its software architecture, fire-spread modeling via level-set method, and how it simulates heat fluxes based on wind input.

Contribution

It introduces the WRF-Fire model, combining fire spread simulation with atmospheric modeling, and describes its software design and capabilities.

Findings

The model accurately simulates fire spread based on wind conditions.

It computes latent and sensible heat fluxes during fire events.

The software architecture supports integration within the WRF framework.

Abstract

We describe the coupled atmosphere-wildfire model WRF-Fire, which is distributed as a part of WRF. The fire module is based on a fire-spread model, implemented by the level-set method. In each time step, the fire module takes the wind as input and returns the latent and sensible heat fluxes. We report on the software architecture and features of the software.
