Abstract: &Space Physics BRussian Ksolar atmosphere// On the basis of macroscopic description of weakly-ionized plasma in a quiet region of the lower atmosphere of the Sun, the possibility of electron-density inhomogeneity formation by turbulent motions of the atmospheric gas is considered. It is assumed that the quasineutral electron-ion plasma is submerged in turbulent flow of neutral gas and has no influence on motion of neutrals. Taking into account the presence of a uniform magnetic field and a background plasma-density gradient, we derived an equation that relates disturbances in electron density to the random velocity field of the gas. Scales of the plasma irregularities and the turbulent pulsations of gas velocity are restricted to an inertial range of the turbulence, an outer scale of which is about a mean granular size of 1000 km. |
