Meteor wind data from the first year of operation of the Falkland IslandsSuperDARN radar (52° S, 59° W) are used to characterize theatmospheric tides and background winds in the upper mesosphere above theSouth Atlantic. Strong (>40 m s<sup>−1</sup>) semidiurnal tides are observed inthe winter time and large amplitude (>60 m s<sup>−1</sup>) bursts of quasitwo-day wave activity are seen in January 2011. Data are in good agreementwith those presented from the SAAMER meteor radar (54° S, 68° W).Comparison with SuperDARN meteor wind data from a geographically similarNorthern Hemisphere site at Goose Bay (53° N 60° W) reveal clearinterhemispheric differences especially in the semidiurnal and terdiurnalcomponents of the tides. The winter time amplitudes of the tides are muchstronger in the Southern Hemisphere than in the north. Background winds areobserved to be significantly more polewards and westwards throughout theyear than those predicted by the empirical horizontal wind model HWM07
