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…

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…

Long-term effects of air pollutants in Finland have been studied by analyzing needle litter of pine (Pinus silvestris L.) and spruce (Picea abies L. Karst) in 13 stands from the years 1958 to 1982. A considerable annual increase in elemental concentrations was observed in 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…

Although bush fires have been common in Australia for many thousands of years (cf. for example, Bermingham, Packham, and Vines, 1971) little is known about the smoke they produce. However, if the practice of prescribed burning - already employed as a routine method of reducing…
