Abstract

The updated database of Forbush effects and interplanetary disturbances (https://tools.izmiran.ru/feid) is used for an extensive analysis of various characteristics of events caused by the influence of interacting solar wind disturbances on the near-Earth space. In particular, the cases of different combinations of the pair interaction of high-speed streams from coronal holes and coronal mass ejections over the long period from 1995 to 2022 are considered. Variations in the flux of galactic cosmic rays (with a rigidity of 10 GV) and changes in the parameters of the interplanetary medium and geomagnetic activity are described. It is shown that the degree of mutual influence depends on the time between the detection of neighboring events; with the most pronounced changes in various parameters for events whose interaction occurred before reaching Earth’s orbit. It is also established that in interacting solar wind disturbances not only the extremes of the parameters of cosmic rays, interplanetary medium, and geomagnetic activity but also their time profiles are subject to changes.

相互作用的太阳风扰动的一些特征

摘要利用更新的福布什效应和行星际扰动数据库（https://tools.izmiran.ru/feid）对相互作用的太阳风扰动对近地空间的影响所引起的事件的各种特征进行了广泛分析。特别是考虑了从 1995 年到 2022 年这一漫长时期内日冕洞高速流和日冕物质抛射成对相互作用的不同组合情况。描述了银河宇宙射线（刚度为 10 GV）通量的变化以及行星际介质和地磁活动参数的变化。研究表明，相互影响的程度取决于相邻事件的探测时间间隔；在到达地球轨道之前发生相互作用的事件，其各种参数的变化最为明显。研究还确定，在相互作用的太阳风扰动中，不仅宇宙射线、行星际介质和地磁活动参数的极值会发生变化，它们的时间曲线也会发生变化。

期刊介绍： Geomagnetism and Aeronomy is a bimonthly periodical that covers the fields of interplanetary space; geoeffective solar events; the magnetosphere; the ionosphere; the upper and middle atmosphere; the action of solar variability and activity on atmospheric parameters and climate; the main magnetic field and its secular variations, excursion, and inversion; and other related topics.
