Abstract
The results of reconstructing the radial dependence of the gas density in the core of a fire tornado model based on the results of laser transillumination are presented. It is shown that the position of the energy gravity centroid of the beam passing through the flame is quite sensitive to regular spatial density variations in the tornado core. Estimates of the transverse size of the core and the temperature in the combustion region are obtained, which correspond to the results of measurements by other methods
