Whether duration of the recovery phase of magnetic storm depends on the development rate of storm at its main phase?

Abstract

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: (1, 2) compression regions CIR and Sheath, and (3) body of interplanetary CME (magnetic clouds and Ejecta). Our analyze shows that the duration of recovery phase correlates with the storm development rate for CIR- and Sheath-induced storms, and does not correlate for ICME- induced storms.
