| Zusammenfassung |
| Cosmic ray induced ionization (CRII) is an important factor of outer
space influences on atmospheric properties.
Variations of CRII are caused by two different processes – solar activity
variations, which modulate the cosmic ray flux in interplanetary space,
and changes of the geomagnetic field, which affects the cosmic ray access
to Earth.
Migration of the geomagnetic dipole axis may greatly alter CRII in some
regions on a time scale of centuries and longer.
Here we present a study of CRII regional effects of the geomagnetic field
changes during the last millennium for two regions: Europe and the Far East.
We show that regional effects of the migration of the geomagnetic dipole axis
may overcome global changes due to solar activity variations. |
