Abstract

The magnetosheath is an integral element of solar–terrestrial relations. The paper analyzes the influence of the solar wind parameters and their variability, as well as the topology of the bow shock on the characteristics of plasma turbulence in the magnetosheath on scales corresponding to the transition from the inertial region of a turbulent cascade to the dissipative one. The analysis is based on extensive statistics of measurements of the BMSW instrument with high time resolution on board the Spektr-R satellite in the magnetosheath in 2011–2018. It is shown that the variability of the solar wind plasma density and the interplanetary magnetic field magnitude, as well as the angle between the normal to the bow shock and the interplanetary magnetic field has the greatest influence on the form of the turbulent cascade directly behind the bow shock.

弓激波后湍流叶栅特性对太阳风参数动力学的依赖

摘要

磁荒是太阳-地面关系的一个组成部分。本文分析了太阳风参数及其变异性的影响，以及弓激波的拓扑对磁石场中等离子体湍流特性的影响，其尺度对应于从湍流叶栅的惯性区域到耗散叶栅的过渡。 。该分析基于Spektr-R上具有高分辨率的BMSW仪器的大量测量统计数据卫星在2011–2018年的磁石场中。结果表明，太阳风等离子体密度和行星际磁场强度的变化以及弓激波法线和行星际磁场之间的夹角对湍流级联形式的直接影响最大。鞠躬震惊。
