Scientific paper

A scanning Fabry-Perot spectrometer (FPS), located at Mawson station, Antarctica (67 deg S, 63 deg E, invariant latitude 70 deg S) was used to obtain vertical wind, temperature, and emission intensity measurements from the 558-nm emission of atomic oxygen. The measured temperature is used to assign an approximate emission height to the observations. A spaced-antenna partial-reflection radar was run concurrently with the FPS from which the presence of enhanced ionization in the D-region could be inferred from the return heights and strengths of the echoes. Large upward winds of approximately 30 m/s, at altitudes less than 110 km, appear to be a direct response of the neutral atmosphere to intense auroral events. It is suggested that the observed upwelling is a result of particle heating at heights below the principal emission height.
