The lofting of firebrands from bushfires into a background atmospheric flow can lead to spotting downwind of the fire front. Spotting is a hazardous phenomenon because it leads to both unpredictable and accelerated fire spread, as winds aloft are often in a different direction from and faster than the near-surface winds. Here we use a two-stage modelling process to address some of the uncertainty associated with spotting, by quantifying the lateral and longitudinal spread in the landing location of potential firebrands and how this spread is affected by the dynamics of the fire plume.
