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

TL;DR

This study investigates how the recovery phase duration of magnetic storms relates to the storm's development rate, revealing correlations for some interplanetary drivers but not others, enhancing understanding of storm dynamics.

Contribution

It compares the dependence of recovery phase duration on storm development rate across different interplanetary drivers, highlighting driver-specific behaviors.

Findings

Recovery duration correlates with development rate for CIR and Sheath storms.

No correlation found for ICME-induced storms.

Results improve understanding of magnetic storm recovery mechanisms.

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.
