Abstract

One perturbed type of solar wind and magnetospheric disturbance drivers is the compression region in front of fast ICMEs—the Sheath region. In front of this region, an interplanetary shock is observed in approximately half of cases. However, the parameters and their time profiles in these two types of the Sheath region differ comparatively little. Therefore, the Sheath region without a shock is as geoeffective as the Sheath region with a shock: the Sheath region in the first case generated almost 10% of magnetic storms with a minimum Dst < –50 nT of all the magnetic storms for 1976–2017 with identified interplanetary drivers. Many authors do not analyze this driver (for this reason, we call it the “lost driver”); therefore, their studies contain incorrect conclusions on solar–terrestrial physics.

识别大型太阳风的类型及其在磁层物理中的作用的一些问题：4.“失去驱动力”

摘要

太阳风和磁层扰动的一种扰动类型是快速ICME前面的压缩区-鞘区。在该区域的前面，大约一半的情况下会观察到行星际冲击。但是，这两种类型的鞘区域中的参数及其时间分布差异很小。因此，没有电击的鞘区域与有电击的鞘区域一样具有地质效应：在第一种情况下，鞘区域产生了几乎10％的磁暴，其最小Dst <–50 nT，在1976–2017年的所有磁暴中与确定的行星际驱动器。许多作者没有分析此驱动程序（因此，我们称其为“丢失的驱动程序”）；因此，他们的研究包含关于日地物理学的错误结论。
