Comparative Evolutionary Analysis of Dipole and Non-Dipole Components of Geomagnetic Energy
S. V. Starchenko,
S. V. Yakovleva
Abstract:The total energy of the potential geomagnetic field (up to the core-mantle boundary) is divided into dipole and non-dipole parts, which are determined by their evolution and frequency properties. The calculations presented here are based on the available and sufficiently reliable COV-OBS.x2 geomagnetic field model that covers the period of 1840–2020. The proposed approximations for longer periods are preliminary, as further work is required to estimate errors through comparison with other historical observatio… Show more
