论文摘要
在太阳循环23-24中，太阳能活动明显下降，因此，太阳风参数减少了。根据1976-2019周期的Omni碱基的测量值，使用双层超级式上的Epoch方法研究了磁层干扰的主要太阳能参数和磁层指数的时间概况。该研究的主要任务是比较21-22太阳能周期高太阳能活动时期的时间曲线，以及在23-24太阳能周期时的低活动时期。获得以下结果。 （1）分析在最低时期期间没有显示驾驶员持续时间的统计学显着变化。 （2）低活性时期中所有类型SW的所有参数的时曲线具有与高活性时期相同的形状，但位于参数的较低值。 （3）在CIR事件中，太阳风流的经度角具有特征性的S形，但是在低活动时期，它在更大的范围内而变化。
In solar cycles 23-24, solar activity noticeably decreased, and, as a result, solar wind parameters decreased. Based on the measurements of the OMNI base for the period 1976-2019, the time profiles of the main solar wind parameters and magnetospheric indices for the main interplanetary drivers of magnetospheric disturbances (solar wind types CIR, Sheath, ejecta and MC) are studied using the double superposed epoch method. The main task of the research is to compare time profiles for the epoch of high solar activity at 21-22 solar cycles and the epoch of low activity at 23-24 solar cycles. The following results were obtained. (1) The analysis did not show a statistically significant change in driver durations during the epoch of minimum. (2) The time profiles of all parameters for all types of SW in the epoch of low activity have the same shape as in the epoch of high activity, but locate at lower values of the parameters. (3) In CIR events, the longitude angle of the solar wind flow has a characteristic S-shape, but in the epoch of low activity it varies in a larger range than in the previous epoch.
