≥1000 acres) in this region have been increasing in the past few decades2, causing a tremendous socioeconomic burden in terms of devastating casualties and losses, soaring fire prevention and suppression costs, and rising public health risk due to short-term and long-term fire smoke exposure...
Thus the historical perspective afforded by tree-ring analysis and by charcoal and pollen analysis adds new dimension to the concept of climax. In a fire-dependent forest one may consider equilibria on two scales—a long-range equilibrium represented by the entire ecosystem, in which fire is the...
fire geometry, and the ambient meteorological profile44. While a weak correlation exists between the fire intensity and plume top height30,45, atmospheric stability acts to limit the buoyant plume rise30,46by inducing plume injection/smoke detrainment. As the plume rises, environmental eddies entrai...
