A Phenomenological Model for Reversals of the Geomagnetic Field
1989We consider a system made by N point interacting dipoles, each of them having a finite lifetime. A renewal process for the dipoles gives the time evolution of the system. When the number N of dipoles is low, and for a wide range of the coupling between the dipoles, we observe sudden transitions or excursions between two polarised states.

Operational modelling of geomagnetic fields and geomagnetically induced currents
2021Geomagnetically induced currents (GICs) have long been known to affect power systems adversely. Modelling these GICs usually involves consideration of a chain of coupled systems. The scope of the modelling chain spans multiple disciplines, from solar physics through to geophysics and power engineering.

An Equivalent Source Model for the Geomagnetic Field
2013A new model for the geomagnetic field is presented. It does not rely heavily on the present-day field, which has some ephemeral characteristics, but mostly on paleomagnetic data from lava flows, in particular the large Icelandic data set. The model consists of an axial dipole and vertical off centered dipoles representing the non-axial-dipole field ...

Regional geomagnetic field model for Croatia
2015Geomagnetic components at Croatian repeat stations and ground survey sites, as well as European observatories and repeat stations, were used to obtain a regional geomagnetic model over Croatia at 2009.5 epoch. Different models were derived, depending on input data, and the modelling techniques were Adjusted Spherical Harmonic Analysis and Spherical ...

Models of the geomagnetic field on the territory of the Republic of Macedonia
2008The aim of this paper is to present various geomagnetic field models of Macedonia based on measurements at repeat stations as well as satellite data covering this region. At first a theoretical basis of the geomagnetic field, spherical cap harmonical model and polynomial model will be given.

On The Modeling Of The Regional Geomagnetic Field
2006Cilj rada bio je regionalno modeliranje glavnog magnetskog polja i njegove sekularne promjene primjenom sferne harmoničke analize na kuglinoj kaloti SCHA, tehnike (Spherical Cap Harmonic Analyses). Europsko područje izabrano je za modeliranje, budući je mreža geomagnetskih opservatorija ovdje najgušća.
