SV
Spatio-Temporal Gravity Wave Source Variability
(Preusse, Ern, Achatz, Bölöni)
The goal of this project is to understand the role of gravity wave sources in shaping the global distribution of GWs. Satellite data and ray tracing are used for optimizing the parameters in state-of-the-art source parameterizations that are then coupled to the GW model (MS-GWaM) in UA-ICON in order to replace conventional GW parameterizations there. It will address the comparative relevance of the various GW sources for GW dynamics in the whole atmosphere, and the contribution of the flow dependence of GW sources to GW momentum-flux intermittency.
