Abstract

Currently, the problem of geospace storms and their components, geomagnetic storms, is one of the most important problems in solar-terrestrial physics and space geophysics. The exploration of the geospace and its use for the needs of civilization has led to the fact that our life is increasingly dependent on the manifestations of solar-terrestrial processes, the state of atmospheric-space weather, and ground-to-space systems of various purposes. The more technologically advanced our civilization becomes, the more vulnerable it is to the processes taking place on the Sun, manifestations of solar-terrestrial relationships, and variations in atmospheric-space weather. These circumstances determine the relevance and continuous scientific and practical significance of studies into the manifestations of solar-terrestrial processes and their consequences. Geospace (geomagnetic) storms can be accompanied by a number of effects: variations in the parameters of the atmosphere and geospace; deceleration of spacecraft; impact of increased cosmic radiation on crew and electronic equipment in spacecraft and aircraft; disturbances of conditions of radio wave propagation and channels of radio communication, radio navigation, radio ranging, radio position finding, radio astronomy, and remote sensing; the induction of currents in power transmission lines, cable lines, pipelines, automated railway systems; and the impact on weather- and climate-forming systems. In addition to the physical effects of individual geomagnetic storms, which are described in a large number of scientific papers, a statistical analysis of the parameters of the solar wind, interplanetary magnetic field, and geomagnetic storms over long periods is of interest. The purpose of this study is to statistically analyze the parameters of the solar wind disturbed by solar storms, the interplanetary magnetic field, and the geomagnetic activity indices over the period of solar cycle 24 (2009–2020). The main statistical characteristics of the disturbed solar wind parameters responsible for the geomagnetic storm origins (153 storms in total) over solar cycle 24 have been estimated. The main statistical characteristics of the components of the disturbed interplanetary magnetic field have been estimated, and the main statistical characteristics of the geomagnetic field indices have been obtained. With respect to magnetic activity, solar cycle 24 was quieter than solar cycle 23.

太阳活动第24周期地磁暴统计特征

摘要

目前,地球空间风暴及其组成部分地磁暴问题是日地物理学和空间地球物理学中最重要的问题之一。对地球空间的探索及其对文明需求的利用导致我们的生活越来越依赖于日地过程的表现、大气-空间天气的状态以及各种地对空系统。目的。我们的文明在技术上越先进,它就越容易受到太阳上发生的过程、日地关系的表现以及大气-空间天气变化的影响。这些情况决定了研究日地过程及其后果的相关性和持续的科学和实际意义。地球空间(地磁)风暴可能伴随着许多影响:大气和地球空间参数的变化;航天器减速;宇宙辐射增加对航天器和飞机上的机组人员和电子设备的影响;无线电波传播条件和无线电通信、无线电导航、无线电测距、无线电定位、射电天文学和遥感信道的干扰;在输电线路、电缆线路、管道、自动化铁路系统中感应电流;以及对天气和气候形成系统的影响。除了大量科学论文中描述的单个地磁暴的物理影响之外,对太阳风、行星际磁场、长期的地磁暴是令人感兴趣的。本研究的目的是统计分析第24个太阳周期(2009-2020)期间受太阳风暴干扰的太阳风参数、行星际磁场和地磁活动指数。已经估计了在太阳周期 24 期间造成地磁风暴起源(总共 153 场风暴)的受干扰太阳风参数的主要统计特征。估计了受扰行星际磁场分量的主要统计特征,获得了地磁场指数的主要统计特征。就地磁活动而言,第 24 个太阳周期比第 23 个太阳周期更安静。本研究的目的是统计分析第24个太阳周期(2009-2020)期间受太阳风暴干扰的太阳风参数、行星际磁场和地磁活动指数。已经估计了在太阳周期 24 期间造成地磁风暴起源(总共 153 场风暴)的受干扰太阳风参数的主要统计特征。估计了受扰行星际磁场分量的主要统计特征,获得了地磁场指数的主要统计特征。就地磁活动而言,第 24 个太阳周期比第 23 个太阳周期更安静。本研究的目的是统计分析第24个太阳周期(2009-2020)期间受太阳风暴干扰的太阳风参数、行星际磁场和地磁活动指数。已经估计了在太阳周期 24 期间造成地磁风暴起源(总共 153 场风暴)的受干扰太阳风参数的主要统计特征。估计了受扰行星际磁场分量的主要统计特征,获得了地磁场指数的主要统计特征。就地磁活动而言,第 24 个太阳周期比第 23 个太阳周期更安静。以及第 24 个太阳活动周期(2009-2020 年)的地磁活动指数。已经估计了在太阳周期 24 期间造成地磁风暴起源(总共 153 场风暴)的受干扰太阳风参数的主要统计特征。估计了受扰行星际磁场分量的主要统计特征,获得了地磁场指数的主要统计特征。就地磁活动而言,第 24 个太阳周期比第 23 个太阳周期更安静。以及第 24 个太阳活动周期(2009-2020 年)的地磁活动指数。已经估计了在太阳周期 24 期间造成地磁风暴起源(总共 153 场风暴)的受干扰太阳风参数的主要统计特征。估计了受扰行星际磁场分量的主要统计特征,获得了地磁场指数的主要统计特征。就地磁活动而言,第 24 个太阳周期比第 23 个太阳周期更安静。估计了受扰行星际磁场分量的主要统计特征,获得了地磁场指数的主要统计特征。就地磁活动而言,第 24 个太阳周期比第 23 个太阳周期更安静。估计了受扰行星际磁场分量的主要统计特征,获得了地磁场指数的主要统计特征。就地磁活动而言,第 24 个太阳周期比第 23 个太阳周期更安静。
