Scientific paper

At high geomagnetic latitudes, thermospheric wind flows are dramatically affected by the combined effects of magnetospheric ion convection and Joule and particle heating. Thermospheric winds have been observed by ground based and space-borne Fabry-Perot interferometers. Since the 1982/1983 winter, a prototype Doppler Imaging System has been operated at Kiruna (67.84 deg N, 20.42 deg E). This instrument maps thermospheric wind flows over a region some 500 km in diameter centered on Kiruna and has observed many interesting features in the thermospheric wind fields. In particular, strong local wind gradients, rapid wind reversals and small scale structures are regularly observed, particularly during geomagnetically disturbed nights.
