Rétroactions des incendies de forêt sur le vent : exemples mesurés sur parcelles végétales expérimentales dans le sud-est de la France.

Abstract : It is well known that wind plays a major role in forest fire propagation. However, the fire itself strongly influences wind characteristics by accelerating wind speeds near the flames. This phenomenon has been observed by fire fighters but rarely quantified. The objective of the study was to measure changes in wind characteristics during field scale experiments. It was observed that not only does wind speed pick up in proximity to the fire front but strong convective currents generated by the fire reinforce vertical wind speeds as well.
