| Popis: | This paper presents the experimental results for the circulation in the 80–110 km height region obtained at Kazan State University in the period of the MAC/SINE International Campaign in 1987. A zonal wind reversal was recorded at heights of about 89 km, with easterly winds below 89 km, and westerly winds above 89 km ; for tidal motions, the amplitude and phase modulation were defined. The presence of waves with scales representative of tidal and synoptic motions is typical for zonal and meridional circulations in the summer period. |
