Abstract

Infrasound waves generated by auroras are usually recorded at high latitudes during periods of high geomagnetic activity. These waves are often characterized by high apparent velocities (usually from 400 to 1000 m/s), which means that their source locates at a high altitude. Currently, the relation between the atmosphere electric-field variations and infrasound in the near-surface atmospheric layer during magnetospheric substorms is determined. However, for the full-scale analysis of the said interaction, we must have a predictive picture of the infrasonic atmospheric response, which raises the need for its modeling.
