Abstract

Computations of momentum flux were made for the meteor wind data collected at Atlanta (34°N), during the period August 1974-March 1978. Substantial transport of momentum due to diurnal tide during summer and semidiurnal tide during winter was observed over the station. Monthly mean momentum flux variations of diurnal and semidiurnal tides exhibited oscillations with periods of about six and four months respectively. The height variations of annual mean momentum flux due to diurnal and semidiurnal tides revealed poleward flux throughout the height region 82-98 km and severe damping of momentum flux due to diurnal tide between the heights 90 and 92 km. The results of the present study relating to the northern hemisphere mid-latitude station are compared with those of Adelaide (35°S), the southern hemisphere mid-latitude station.
