Coupled Atmosphere-Wildland Fire Environment (CAWFE)

Coupled Atmosphere-Wildland Fire Environment (CAWFE)

The CAWFE Modeling System contains two parts: a numerical weather prediction model and a fire behavior model that simulates the growth of a wildfire in response to weather, fuel conditions, and terrain. These are two-way coupled to constantly exchange information so that heat and water vapor fluxes from the fire alter the atmospheric state, notably producing fire winds, as the evolving atmospheric state and changes in humidity (including effects from the fire) simultaneously affect fire behavior, notably how fast and in what direction the fire propagates. The model is described in Clark et al. (2004) and Coen 2005a.  Coen (2013) documents the model equations.
