| Zusammenfassung |
| Magnetic clouds (MCs), and more generally, interplanetary coronal mass
ejections (ICMEs), are believed to be the interplanetary counterparts of
CMEs. The link has usually been shown by taking into account the CME launch
position on the Sun, the expected time delay and by comparing the orientation
of the coronal and interplanetary magnetic field. Making such a link more
quantitative is challenging since it requires a relation between very different
kinds of magnetic field measurements: (i) photospheric magnetic maps, which
are observed from a distant vantage point (remote sensing) and (ii) in-situ
measurements of MCs, which provide precise, directly measured, magnetic field
data merely from one-dimensional linear samples. The association between
events in these different domains can be made using adequate coronal and MC
models. Then, global quantities like magnetic fluxes and helicity can be
derived and compared.
This review paper describes all the general trends found in the above association
criteria. A special focus is given for the cases which do not follow the earlier
derived mean laws since interesting physics is usually involved. |
