Numerical Simulation of the Time Evolution of Small-Scale Irregularities in the F-Layer Ionospheric Plasma
Figure 1
The time variations of maximal (top curve) and minimal (bottom curve) values of the relative decrease of the electron concentration, computed at all grid cells of the simulation region. Also, the time variation of the relative decrease of the electron concentration, calculated at the center of the simulation region (middle curve). The results were obtained for the first situation with the start from the completely electrically neutral state. The values are given in units of 10−6. The normalized time, , that is, the time in units of the equilibrium period of Langmuir oscillations of electrons, , is shown on the abscissa.
