The CISM Coupled Magnetosphere-Ionosphere-Thermosphere (CMIT) model, which includes two-way coupling between the Thermosphere/Ionosphere Nested Grid (TING) Model and the Lyon-Fedder-Mobarry (LFM) global magnetosphere MHD code, is run to investigate the near Earth space weather response to the 12-15 May 1997 geomagnetic storm. In this paper we will focus on the high and middle latitudes thermospheric wind variations during the storm. Two major processes change the storm time neutral wind circulation: an enhanced ion drag effect that forces the neutrals to follow the expanded ion convective drift, and an intensified Joule heating effect that increases the high latitude pressure gradient and thus changes the global wind pattern. We will discuss temporal and spatial evolutions of neutral wind changes after the storm commencement, and the time cadence of neutral wind recovery after the storm. Of particular interest to this study is a jet of neutral winds that occurs in the middle latitudes during the storm.
