论文摘要
考虑了从极端到弱的各种强度的140多个孤立的非电流地磁风暴（GMS），这些强度被考虑在太阳喷发源（冠状质量弹出，CMES）中可靠地鉴定出来。该分析旨在获得可能完全了解CME的传播时间与从太阳到地球的旋转冠状质量弹出（ICME）之间的关系（更确切地说，更确切地说，更确切地说，时间间隔DTP从爆发到爆发到相应的GMS的峰值到峰值的最大强度，该GM的最大程度的gem agg geom dem dem dem aignance dem aignation rysectians the rysectians dem aighnectians dem aightiment the Inspectians the rysect rysectians geom。两组事件被选出：其中一个包括GMS，其来源是来自活动区域（AR事件）的爆发，其他GMS是由位于ARS外（QS事件）的太阳静态区域引起的细丝爆发引起的。 DTP -DST平面上大量分析事件的分布证实并实质上阐明了已知的规律性。与QS事件相比，AR事件的特征在于较短的运输时间（DTP〜1-4天）和更强的GMS（DST最高为-600 nt）（DTP 〜3-5天，DST> -200 nt）。对于两组的事件，CMES/ICMES的较短运输时间，更激烈的GMS；特别是，对于AR事件，当DTP从4天下降到1天时，DST平均从-100降低到-470 NT，并且可以达到-900 nt。从GMS的性质及其来源的角度来看，获得的结果意味着CMES/ICMES的速度和由它们传递的磁场的强度都在很大程度上取决于相应喷发的参数，尤其是由喷发磁通量和释放的能量确定。
More than 140 isolated non-recurrent geomagnetic storms (GMSs) of various intensities from extreme to weak are considered, which are reliably identified with solar eruptive sources (coronal mass ejections, CMEs). The analysis aims to obtain a possibly complete picture of the relationship between the transit time of propagation of CMEs and interplanetary coronal mass ejections (ICMEs) from the Sun to the Earth (more precisely, the time interval dtp from the moment of an eruption until the peak of the corresponding GMS) and the maximum intensity of this GMS, as measured by the disturbance storm time geomagnetic index Dst. Two groups of events are singled out: one includes GMSs, the source of which was an eruption from an active region (AR events), the other GMSs caused by filament eruptions from quiescent areas of the Sun located outside ARs (QS events). The distribution of the large number of the analyzed events on a dtp - Dst plane confirms and substantially clarifies the known regularities. The AR events are characterized by a shorter transit time (dtp ~ 1-4 days) and much stronger GMSs (Dst up to -600 nT mainly) in comparison with the QS events (dtp ~ 3-5 days, Dst > -200 nT). For events of both groups, the shorter transit time of CMEs/ICMEs, the more intense GMSs; in particular, for AR events when dtp declines from 4 to 1 day, Dst decreases on average from -100 to -470 nT and can reach -900 nT. From the point of view of the nature of GMSs and their sources on the Sun, the obtained results mean that both the speed of CMEs/ICMEs and the strength of the magnetic field transferred by them are largely determined by the parameters of the corresponding eruptions, in particular, by the eruptive magnetic flux and the released energy.
