The main study results on atmospheric gravity waves(GWs)in last fifty years are summarized,which include the source,dynamical Mechanism and obervation of GWs.Results show that the GWs are mainly excited by jet stream,followed by deep convection,mountain terrain and water vapor.GWs propagation velocity is proportional to the GWs amplitude and pulse width.Normally GWs are strengthen in the stability atmosphere.Latent heating is favorable to the formation of GWs,and thermal heating not.The GWs detection means include micro-pressure devices,satellites,radar,etc..the GWS activity characteristics have been analyzed by detection.GWs play a role in exciting and enhancing the typhoon,rainstorm and hail storm.
