Prescribed Burn 2-57 was the second of four prescribed burns studied in 1957. In this burn we were particularly interested in studying air flow on the lee side of a ridge oriented approximately at right angles to the prevailing wind. Experience has shown that erratic fire…

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…

From the text ... 'Early and reliable detection of forest fires is the keystone of efficient fire control. It means the discovery of fires while they are small and results in lower suppression costs and damages. Private, State, and Federal fire-protection agencies throughout the…

'Control burning of brush is now a common practice in range improvement in California. Frequently, before burning, some or all of the brush is mashed down with mechanical equipment or killed by chemical sprays. To learn how destructive such fires are to wildlife, a study was…

[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…
