Long-Range Spotting by Bushfire Plumes: The Effects of In-Plume Turbulence on Firebrand Trajectory

Large-eddy simulations of bushfire plumes are combined with firebrand trajectory calculations to estimate the effects of in-plume turbulence on firebrand transport.  In-plume turbulence  substantially lengthens the maximum spotting distance AND increases the lateral and longitudinal spread of firebrand landing positions.
