The length of a normal buoyant diffusion flame is limited by the entrainment of air. If the flame is subjected to a mild vortical air flow, entrainment may be inhibited with the result that flame is transformed into a fire whirl having a flame length many times greater than that of the original flame.
The following two references show pictures of a laboratory-induced fire whirl and a naturally occurring whirl in a forest fire.
The articles contain a mathematical treatment of epically esoteric proportions, but the pictures and description of the lab experiment tell the story.
