Abstract

The variations of the ionospheric current in the lower ionosphere and the plasma density of the upper ionosphere have been studied based on the monitoring of the horizontal component of the geomagnetic field induction and height-frequency sounding of the critical frequency of the ionosphere F layer at the Moscow Observatory. It is shown that, in the spectra of time variations of the geomagnetic field and the critical frequency of the F2 layer in the range of planetary waves in winter, there are both harmonics associated with solar activity and harmonics corresponding to quasi-5-, 10-, and 16-day planetary waves. The involvement of geomagnetic field registration data for a 20-year time interval (from 2001 to 2020) have made it possible to identify more subtle effects, namely, the harmonics associated with the modulation effect of longer period variations and tidal effects are identified.

莫斯科天文台（伊兹米兰）测量的电离层高度的大气行星波

摘要

通过地磁场感应水平分量监测和电离层F层临界频率高频探测，研究了电离层下层电离层电流和电离层上层等离子体密度的变化。莫斯科天文台。结果表明，冬季行星波范围内地磁场随时间变化的频谱和F2层临界频率中，既有与太阳活动相关的谐波，也有对应于准5、10的谐波。 - 和 16 天行星波。20年时间间隔（从2001年到2020年）的地磁场登记数据的参与使得识别更微妙的效应成为可能，即识别与较长周期变化的调制效应和潮汐效应相关的谐波。
