To determine the environmental cons within a fire storm, an analytical model was developed which describes the variations with altitude of velocity, temperature, and gas composition within the convection column over a burning area. The analysis is based on an integral method and rep resents an extension of previous analyses of bouyant plumes to include the effects of combus tion and composition variations within tholumn, and radiation losses from the hot gases. Computer solutions are presented showing the effects on the column of burning area, entrainment coeffi cient, lapse rate of the atmosphere, and fuel supply rate. The nature of the analysis makes the results inapplicable to prediin of ci tions at ground level. Refinements i th eoe suggested for extension of the range of va lidity to ground level. Author
