During this talk, the evidence that stratified turbulence is present in the middle atmosphere will be presented. The study is based on the results of General Circulation Model simulations and observational data, such as radar and rocket-borne measurements. In particular, it will be shown that mesoscale dynamics in the middle atmosphere is not always dominated by gravity waves, and layered vortical structures can play a significant role, as well.
The importance of stratified turbulence in the formation of the cold summer mesopause at mid to high latitudes will also be discussed.
