Estimated possibility of using E. A. Ponomarev's model of magnetospheric substorm to analyse geomagnetic disturbances during the magnetic storm of 14, 15 December 2006

We have simulated spatial distributions of pressure and fluxes of precipitating particles of magnetospheric plasma for the strong magnetic storm of 14, 15 December 2006. In the simulation, we have applied a model designed by E.A. Ponomarev. «Geotail» and ACE satellite data have been used to specify realistic initial and boundary conditions. The model results have been compared with the spatial distribution of the field of geomagnetic disturbances observed by ground-based magnetic observatories during the storm. The results obtained show that the model (in its current form) provides, in general, agreement between latitude displacements of electron precipitations and those of auroral electrojets, but does not reflect the longitude pattern of the latter. It does not mainly simulate a powerful westward electrojet that was observed by all auroral zone observatories during the main phase of the magnetic storm.
