Beyond Spotting and Classical Heat Transfer: A Conceptual Hypothesis for Delayed Secondary Ignition in Extreme Wildfires

This manuscript presents a falsifiable conceptual scientific hypothesis concerning delayed secondary ignition phenomena observed in extreme wildfire environments. The proposed framework explores whether transient horizontally advected combustion-derived reactive gaseous fronts may preserve sufficient thermal and chemical ignition potential to contribute to delayed ignition independently of direct flame impingement and conventional spotting mechanisms. This work is intended as a scientific investigational framework for wildfire behavior research, firefighter safety analysis, and extreme fire dynamics discussion.
