From the introduction letter ... 'This publication deals with fire, a significant force in the forest environment. Depending upon land management objectives for a specific area, plus a host of environmental variables, fire will sometimes be an enemy, at times a friend, and…

From the text... 'An ideal forest fire detection system would detect fires the instant they start, day or night, under any condition of visibility. Additionally, it could distinguish potentially dangerous fires from those that would not concern fire suppression forces. Although…

The control of wildfires in forested areas may not always be a desirable objective since certain benefits can result that are important enough to warrant prescribed burning in some cases. Included in these benefits is the control of harmful insects and plant diseases and of…

The development of the smoke cloud from a summer wildfire in a forest area was studied on a radar screen. In conjunction with photographs taken at the same time, it has been possible to follow the variations in height of both the top and bottom of the smoke column as it was…

Results of the 1971inventory of fire use in Georgia indicate that 589,633 acres were burned for agricultural purposes and 527,557 acres were presribed burned for forestry purposes. About 95 percent of this burning was done in the southern half of the State. It was estimated that…

During the last 17 days of April 1971, smoke from wildfires in the Florida Everglades drifted over the east coast of southern Florida. Smoke restricted visibilities 67.9% of the time at Palm Beach International Airport, and aircraft operations were 11.9% less than for an…

Mass fires are being investigated through a series of large-scale test fires. Preliminary results indicate: (a) air flow patterns that create eddies can result in fire vortices when fires is present; (b) the lower part of the convection column consists of a series of small…

The combustion products (smoke) from forest wildfires or prescribed burns are often considered on a par with any other emission that might affect air quality. But enough is known about smoke from woody fuels to indicate that its importance is limited almost entirely to…

A cinematographic film of a tornado which formed over a severe bushfire in 1962 in Victoria has been analysed. Notable findings are that a flame rose in the core to a height of 260 feet, that the core velocities were up to 205 m.p.h. vertically, at least 20-30 m.p.h.…

The control of large fires is a problem of continuing concern to the Forest Service, other public agencies, and private owners of forest and rangeland. A few large fires each year account for all but a small share of the Nation's forest fire losses. In time of war, this problem…

Post-harvest burning of straw and stubble in grass fields is the most valuable cultural practice in grass-seed production in Oregon. Unfortunately, smoke from burning fields sometimes creates a nuisance to others who understandably question the idea. This discussion is presented…
