摘要：

A hydrodynamic model is used to reproduce the atmospheric circulation during forest fires. The dynamics is simulated with an improved model of free convection with allowance for heat flux emission from the fire area. Against the background of the atmospheric circulation patterns obtained, the problem of aerosol evolution and size distribution due to the forest's combustible materials from the fire area was solved. The evolution of soot particles is described by solving the kinetic equations of condensation and coagulation. The results of numerical experiments to develop a process that considers water-vapor condensation in a moist atmosphere are presented.
