Fire Behavior, Weather, and Burn Severity of the 2007 Anaktuvuk River Tundra Fire, North Slope, Alaska

摘要: Abstract In 2007, the Anaktuvuk River Fire (ARF) became largest recorded tundra fire on North Slope of Alaska. The ARF burned for nearly three months, consuming more than 100,000 ha. At its peak in early September, at a rate 7000 ha d−1. conditions potentially responsible this large include modeled record high summer temperature and low precipitation, late-season high-pressure system located over Beaufort Sea, extremely dry soil throughout summer, sustained southerly winds during period vegetation senescence. Burn severity mapping revealed that 80% moderate to extreme severity, while nearby Kuparuk remained small predominantly (80%) severity. While study provides information may aid prediction future fires northern Alaska, fact other occurred 2007 combined burn less 1000 ha...
