Abstract

A large array of experimental data from observations of ionospheric vertical sounding stations located in different regions of the Earth has been used to study the features of long-term (1948–2019) time series of relative variations in the critical frequencies of the ionospheric F2 layer during disturbances. The ionospheric disturbance parameters, such as the amplitudes of positive disturbances recorded at all stations, have demonstrated a statistically significant increase since the 1970s and 1980s. The annual numbers of ionospheric disturbances unrelated to geomagnetic activity also increase. The revealed effects may be associated with atmospheric trends of natural and anthropogenic origin, which enhance the dynamic regime at the F2 layer heights.

不同区域电离层F 2层扰动特性的长期动力学

摘要

来自位于地球不同区域的电离层垂直探测站的大量实验数据已用于研究电离层F 2临界频率相对变化的长期（1948–2019）时间序列的特征。扰动期间的层。自1970年代和1980年代以来，电离层扰动参数，例如在所有台站记录的正扰动幅度，已显示出统计学上的显着增加。与地磁活动无关的电离层扰动的年数量也增加了。揭示的影响可能与自然和人为起源的大气趋势有关，从而增强了F 2层高度的动态机制。
