Title: Atmospheric pressure and velocity fluctuations near the auroral electrojet. Technical report

Technical Report ·
OSTI ID:5035010

The low frequency pressure and velocity perturbations caused by the temporally varying Lorentz force associated with auroral electrojet activity are modelled by calculating the disturbances generated by a two-dimensional, time-dependent current system in a gravitationally stratified, isothermal, windless atmosphere. These calculations provide information about the pattern of gravity waves around the hypothetical electrojet and give estimates of the magnitudes of near-field auroral disturbances in the middle atmosphere. It is suggested that the near-field vertical wind shears may be large enough to affect the development of air turbulence in the auroral zone.
