Summary

This chapter reviews the current state of knowledge on steps in the process of generating a spot fire. Firebrand formation and data on the size and shape of firebrands generated from wildfires are described. Various elements of firebrand lofting and transport modeling, including firebrand aerodynamics, the fire plume characteristics, models for the ambient wind field, model coupling, experimental results, and a discussion on the sensitivity of the model predictions to the inevitable uncertainty in the model input parameters, are examined. Recent work on the physics of firebrand deposition and spot fire generation is noted.
