Fire Simulation with Dry Eucalyptus and Flat Terrain

The early results shown here help to understand the circulation dynamics of a fire storm on a flat land surface.In the past, studies and numerical simulation of forest fires have treated the fire-atmosphere as an uncoupled system. The simulation we show here from 1997 is particulary interesting because a simple, dry-eucalyptus fire model is fully coupled with an atmospheric model to conduct the study. Both ground and canopy fuels are prescribed as are winds, which are forced in a hyperbolic-tangent profile, with 3 m/s at surface and -3 m/s at top of the domain which is 1 km.
