The numerical modeling was carried out for the equatorial Earth ionosphere F-region of conditions by means of the two-dimensional mathematical MI2 model coordinated electrodynamically. It is shown that ionospheric bubbles development time rather strongly depends on the vertical scale of the initial irregularity and strongly depends on the horizontal scale. The ionospheric bubbles developed more slowly at instability generation by a plasma increase, than at instability generation by plasma decrease. Three metric thresholds at initial irregularity scale increase are found experimentally.
Keywords: ionosphere, Rayleigh Taylor instability, mathematical modeling, numerical modeling, metric threshold.
