The numerical calculation carried out using software PHOENICS for non stationary three dimensional case. K-ε model of turbulence is taken into account. It is studied the influence of temperature and wind velocity in boundary layer of atmosphere on the turbulent kinematic viscosity coefficient value and distribution of temperature above the crown forest fire front.
