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…

The Prescribed Burn Fireclimate Survey 1-57 was the first of four prescribed burn surveys in 1957. In this burn we were looking particularly for effects of fire on the wind patterns on the lee side of the fire. Instrumentation, observation techniques, and data collected were…

[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…

The importance of fire for the regeneration of the forests has never been so topical as in our days, when increasing use is made of controlled burning in the interests of forestry. In 1955 about 40,000 hectares of forest land, belonging to the Forest Service and the companies,…
