摘要

摘要利用新的电离层指数对 2023 年 2 月至 3 月电离层垂直和倾斜探测数据进行分析后发现，环型太阳日冕物质抛射导致电离层临界频率 F 层长期下降，而其他类型的日冕物质抛射可能不会导致状态电离层发生重大变化。注意到太阳风和高能质子高速流在发生电离层扰动中可能发挥的作用。给出了塞浦路斯-下诺夫哥罗德航线在地磁扰动期间的距离-频率特性，这表明电离层 F 层发生了强烈变形，并出现了向低空区域传播的 Z 形波扰动。

Earth’s Ionospheric Response to Solar Activity Phenomena in February–March 2023

Abstract

As a result of the analysis of data from vertical and oblique sounding of the ionosphere in February–March 2023 using the new ionospheric index, it was found that solar coronal mass ejections (CMEs) of the loop type lead to a long-term decrease in the critical frequencies F-layer of the ionosphere, while other types of CMEs may not lead to significant changes in the state ionosphere. The possible role of high-speed streams of solar wind and energetic protons in the occurrence of ionospheric disturbances is noted. Distance–frequency characteristics of the Cyprus–Nizhny Novgorod route during geomagnetic disturbances are given, which indicate both a strong deformation of the F-layer of the ionosphere and the appearance of z-shaped wave disturbances propagating to a region of lower altitudes.
