Abstract

A complex mathematical model is considered, which describes atmospheric circulation, aerosol dynamics, and convective cloud formation during forest fires. The dynamics of soot particles is described in terms of kinetic equations of condensation and coagulation. The model incorporates main microphysics processes responsible for the generation of cloud drops on condensation nuclei and their further growth (nucleation, condensation/evaporation, coagulation, sedimentation). The results of numerical experiments are used to analyze specific features of airflow patterns during forest fires, which are caused by the interaction between the fields of wind flow velocity, temperature, and humidity.

Keywords:

dynamics, condensation, coagulation, convective cloud
