Changes in fire severity across gradients of climate, fire size, and topography: a landscape ecological perspective
The authors examined the effects of climate, specifically drought, and local topography on fire severity across a gradient of fire sizes and vegetation types.
The authors found that most, but not all, large fires occurred during the La Niña phase of ENSO. For the Cerro Grande fire, which occurred during an extreme La Niña event, topography had a stronger influence on reducing severity in some areas than the regional effects of climate. Conversely, on several of the fires, topography conducive to fire spread did not produce increased severity, and temperature and wind had a stronger influence on fire effects.
