Advances in wildland fire - atmosphere interactions

Session ID#: 156541

Session Description:
While fuels, weather and topography are the three major components that impact wildland fire behavior, they are interlinked and strongly affected by the states of the lower atmosphere. The fire-atmosphere interaction problem is multiscale – it can be affected by the wind and turbulence levels in the fuel canopy or by the recirculating patterns of wind-flow past a topographic variation or by the effects of large-scale Foehn winds. Advances in this topic are important for developing better modeling and prediction tools for managing fires in forested and wildland-urban-interface environments. This session will present important aspects of wildland fire - atmosphere interactions based on both modeling and observations. Potential topics that impact the ignition, spread and intensity of wildland fires can include: energy balance and partitioning, clouds and shadows, pyrocumulus effects, stability, topographic effects, diurnal and seasonal effects on fuel moisture, canopy turbulence and fuel heterogeneity, convective plume dynamics among others.
