The TRR 181 seminar is held by Dr. Ulrich Achatz (Goethe-Universtität Frankfurt) on
Atmospheric Gravity Waves: Challenges and Solution Strategies
at Universität Hamburg on January 16 at 10 am, Bundesstr. 53, room 22/23 (ground floor).
Even with present and foreseeable computational capabilities, the spatial resolution of atmospheric weather-forecast and climate models is and will remain insufficient to capture many essential processes. Next to clouds and turbulence, subgrid-scale waves and their parameterization are one of the grand challenges of the field. Here, especially buoyancy-driven gravity waves are in the focus. The talk will give an overview of the fundamental properties and atmospheric impacts of these waves. It will describe the lead issues in their handling in models, and it will discuss recent developments towards their solution, ranging from laboratory experiments over theory to atmospheric modeling.
