We investigate seasonal behaviour of acoustic gravity waves (AGWs) in
the thermosphere. For this purpose, measurements of HF Doppler sounding stations
operated by or in cooperation with our institute are used. These measurements
are compared with previously reported studies which employed different techniques
of ionospheric observations. The propagation of AGWs is found to have strong
seasonal dependence. AGWs in summer generally tend to propagate poleward in
summer and equatorward in winter.
