We compare dependences between the storm development rate $|Dst_{min}|/\Delta T$ ($\Delta T$ is the durations of main phase) and the duration of recovery phase of magnetic storms generated by three various types of interplanetary drivers:…

High-speed solar wind streams (HSSs) interact with the preceding ambient solar wind to form Stream Interaction Regions (SIRs), which are a primary source of recurrent geomagnetic storms. However, HSSs may also encounter and subsequently…

As an important source for large geomagnetic storms, an "ICME-in-sheath" is a completely shocked interplanetary coronal mass ejection (ICME) stuck in the sheath between a shock and host ejecta. Typical characteristics are identified from…
