Acoustic-gravity waves (AGW) in the thermosphere are investigated on the basis of observation data from the Dynamics Explorer 2 satellite. It is shown that the planetary AGW distribution consists of regular and sporadic components. A catalogue of AGW waveforms is compiled. Possible surface sources of the AGW generation, namely, tropical cyclones, rocket launchings and earthquakes are investigated. Our sta­tistical analysis reveals no correlation between the AGW gen­eration and tropical cyclones as well as rocket launchings, but it shows some possible relation between the AGW generation and earthquakes.
