Auroral substorm is a basic energy input, coupling and dissipation process. Complex auroral substorm effects are not to be neglected for the thermospheric neutral wind effects, and has important significance on its in-depth study. A self-developed all-sky Fabry-Perot Interferometer (FPI) has been deployed by Chinese Arctic Yellow River Station (78.92°N, 11.93°E) at Ny-Alesund, Svalbard in November 2010, and formal observation has been carried out, which obtained FPI measured data for the first time in domestic. This paper briefly introduces the observations during winter in 2012. Two auroral substorm events on November 12-14, 2012 and December 9-11, 2012 were selected for data processing, and wind fields corresponded to 5 interference rings were calculated. The comparison and analysis between wind field and geomagnetic activity variations during the periods of auroral substorms indicated that the dramatic change of wind speed may be caused by a violent disturbance of geomagnetic activity. Contrastive analyses between auroral images by an all sky camera and FPI interference fringes corresponding line of sight wind field during November 13, 2012, 00:00UT-02:00UT and December 10, 2012, 05:00UT-07:30UT suggest that the enhanced direction is perpendicular to the aurora arc, and it weakens in the direction paralleled with the arc.
