Abstract
The results of mathematical modeling of the flow structure, turbulence characteristic and heat transfer in a convective column occurring during the ground forest fire are presented. The detailed analysis of the temperature, vertical velocity and turbulent kinetic energy distributions along the column's height is conducted. The regression relationships for the change in velocity and temperature along the convective column axis with height are obtained.
