Observation shows that three types of horizontal vortices may form during intense wildland fires. Two of these vortices are longitudinal relative to the ambient wind and the third is transverse. One of the longitudinal types, a vortex pair, occurs with extreme heat and low to…

This paper describes the results of examining the influence of radiative heat transfer on turbulent natural convection above fires in an atmosphere of constant potential temperature, under both the 'opaque' and 'transparent' approximations. It turns out that on the basis of the…

The present-day northern Rocky Mountain vegetation is the product of a long history of geologic and climatic events that have interacted with the species populations composing the regional flora. General concepts relating to the organization, classification, and dynamic nature…

[Excerpted from text] Most experienced firefighters have encountered fire whirlwinds. These whirls, or "fire devils" as they are sometimes called, range in size from small twisters a foot or two in diameter up to violent whirls equal to small tornadoes in size and intensity.…

Late in 1961 the Northern Forest Fire Laboratory initiated a fire detection research program. The primary objective of this program is the development of a system capable of detecting both man-caused and lightning-caused fires day or night through all normally encountered…

Laboratory experiments were conducted to investigate how both mineral soil and moisture content affect the smoldering combustion in forest duff. Peat was used to represent the fermentation and humus horizons (Oe and Oa soil horizons) of a coniferous forest floor nominally called…
