Short summary
The article presents a summary of the main findings of the systematic study of acoustic-gravity waves (AGWs) in the polar thermosphere. This study was based on the in situ measurements made by the Dynamics Explorer 2 spacecraft. It was found out that AGWs in the polar thermosphere are observed within a narrow frequency band and with horizontal wavelengths about 500-600km. The connection between the directions of motion of AGW and polar wind circulation was detected.
