Abstract:

This dataset contains extremal forecast of latitutude (lat), longitude (lon) and intensity of the geomagnetic dipole between 2019 and 2119. The geomagnetic dipole is evolved by a fluid flow at the core-mantle boundary that maximises the rate-of-change of the dipole latitude. The forecast is calculated from the year 2019 assuming that the geomagnetic field is described by the CHAOS-7 dataset. The optimisation procedure is described in https://doi.org/10.3390/geosciences11080318

statement:

The extreme forecast are prepared via the following procedure: 1. The magnetic field at the core-mantle boundary in 2019 is given by the CHAOS-7 geomagnetic field model 2. Using the optimisation methodology published in https://doi.org/10.3390/geosciences11080318, the flow that maximises the instantaneous rate-of-change in dipole latitude is derived. A root-mean-square flow speed of 13 km/yr at the core-mantle boundary is prescribed. Either unrestricted or equatorially symmetric flow geometries can be chosen. 3. The optimal flow is used to evolve the core-mantle boundary magnetic field in time by solving the induction equation via a second order AB time-stepping scheme. 4. After one year of evolution the optimal flow is calculated again from the resulting core-mantle boundary magnetic field 5. Repeat from 3.
