000910713 520__ $$aAtmospheric gravity waves (GWs) are important for turbulence and for driving large-scale circulations in the mid to upper atmosphere. Global circulation models (weather and climate models) do not properly resolve part of the GW spectrum and therefore can not properly reproduce the atmospheric circulations. The models use parameterisation schemes in an attempt to capture the effect of the unresolved GWs. However, parameterisation schemes oversimplify the physical effects in the atmosphere and more complex theories are needed to describe the GWs more realistically. It is widely known that the GW drag amount and the location there-of are incorrect in the general circulation models. This dissertation relies on observations to better understand GWs, which leads to suggestions for improvements in general circulation models. Observations consist of GLORIA (Gimballed Limb Observer for Radiance Imaging of the Atmosphere) and ALIMA (Airborne LIdar for the Middle Atmosphere) instruments onboard the German High Altitude LOng range (HALO) research aircraft. This allows high-resolution measurements from about 5 km to 80 km. ...
