The present simulations of vertical wind changes and associated local horizontal wind changes indicate the reverberations of the night-side thermosphere as the large scale consequences of major high latitude auroral and geomagnetic disturbances. In these simulations, the energetic electron precipitation, and thus thermal plasma densities and Joule and particle heating, essentially covary with the conversion ion velocity across the auroral oval. It is found to be more difficult to simulate systematic downward vertical winds of 50 m/sec than localized regions of temporary upward winds of the order of 200 m/sec.
