A three-year simulation was performed using a gravity wave-resolving general circulation model with realistic boundary conditions. By analyzing the output data in detail, various features of the middle atmosphere dynamics have been clarified quantitatively in terms of the momentum balance including both Rossby-type and gravity-type of waves, the source identification and three-dimensional propagation of gravity waves, the structure and maintenance mechanisms of the tropopause and stratopause, the driving mechanisms of the quasi-biennial oscillation, and the dynamics of baroclinic/barotropic instabilities in the upper mesosphere.
