Resumo
Plasma−dust effects in the martian atmosphere are discussed. A specific feature of the martian atmosphere is the presence of dust grains in a wide range of altitudes. Taking into account the presence of the martian ionosphere and the high conductivity of the medium at lower altitudes, the appearance of plasma systems in the martian atmosphere can be considered quite a common phenomenon. Special attention is paid to dust devils that frequently form in the martian atmosphere and can efficiently lift dust grains. The processes of dust grain charging as a result of triboelectric effect and generation of electric fields in a dust devil are discussed. The dynamics of dust grains in such a vortex is simulated with allowance for their charging and the generated electric field.
