| Zusammenfassung |
| Geomagnetic storm connections to solar eruptive phenomena in solar cycle 23 (SC23) have
been intensively studied and it is a subject of great importance because of their various effects
in our day-to-day life.
We analyse the energy transfer from the solar wind into the magnetosphere during intense
geomagnetic storms defined by Dst ≈¤ -150 nT. There were 29 intense storms during SC23.
We will use the Akasofu parameter (Akasofu, 1981) to compute the ε function and study its
time profile. We compute the energy input efficiency during the main phase of the
geomagnetic storm.
We compute the magnetospheric energy input using the formula introduced by Wang et
al. (2014) and compare these results with the ε function for the geomagnetic storms of
October 29-30, 2003. |
