摘要

Apioneering Bushfire and Natural Hazards CRC project has highlighted the role pyroconvective interactions and spot-fire dynamics play in the spread of fires across a landscape. Fires that burn in close proximity can influence each other due to pyroconvective interactions between individual fires. The same processes can apply to different parts of a single fire line. A typical example is when intense spotting causes many fires to form and coalesce. Interactions between individual spot fires and other parts of the main fire perimeter can increase local rates of spread, in unexpected directions, potentially producing broad, flaming zones that can entrap firefighters, and increase the likelihood of extreme bushfires.
