The time evolution of themagnetic field aligned super-small-scale irregularities in the concentration ofcharged particles, existing in the near-Earth rarefied plasma, is studied withthe help of the model simulation. A new version of the two-dimensionalmathematical model, developed earlier in the Polar Geophysical Institute, is utilizedto investigate the temporal history of the irregularity with circular crosssection, created initially in the near-Earth plasma. The utilized model isbased on a numerical solution of the Vlasov-Poisson system of equations, withthe Vlasov equations describing the distribution functions of charged particlesand the Poisson equation governing the self-consistent electric field. Theresults of simulation indicate that the mobility of the positive ions ought toinfluence essentially on the time evolution of the super-small-scaleirregularities in the concentration of charged particles, existing in thenear-Earth rarefied plasma.
