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…

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.…

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…
