Abstract
Based on statistical analysis of a large array of archival experimental data on the dynamic regime of the ionosphere over Irkutsk, statistical long-term characteristics of the horizontal drift of ionization irregularities over the region of the south of Eastern Siberia have been obtained. The measurements were carried out by the radiophysical spaced-receiver method with a small base of the radio signal reflected from the ionosphere during vertical ground-based radio sounding in 1958–1982. The analysis of the data of long-term measurements confirmed the obvious differences in the nature of the dynamic regime of the lower and upper ionosphere. It is shown that the motion of ionization in the zonal direction is more regular than the meridional drift. The characteristic seasonal features of variations in the amplitudes and directions of horizontal drift motions at altitudes of the ionosphere regions E and F are determined.
摘要在对伊尔库茨克上空电离层动态机制的大量档案实验数据进行统计分析的基础上，获得了东西伯利亚南部地区电离不规则水平漂移的长期统计特征。测量是在 1958-1982 年垂直地面无线电探测期间，利用电离层反射的无线电信号的小基数，通过无线电物理间隔接收器方法进行的。对长期测量数据的分析证实了电离层下部和上部动态机制性质的明显差异。结果表明，电离在地带方向的运动比经向漂移更有规律。确定了电离层 E 区和 F 区高度水平漂移运动的振幅和方向变化的季节特征。
