Impact of Non-Classical Gravity-Wave Dynamics on Middle-Atmosphere Mean Flow and Solar Tides
Tobias Kühner, Georg Sebastian Voelker, Ulrich Achatz
Conventional gravity-wave (GW) parameterizations neglect three aspects of GW dynamics. Instead of momentum and entropy fluxes they use Eliassen-Palm fluxes, thereby neglecting the…
The Impact of Non-Orographic Gravity Waves on Transport and Mixing: Effects of Oblique Propagation and Coupling to Turbulence
Tridib Banerjee, Sebastian Borchert, Young-Ha Kim +7
Gravity waves (GWs) are a fundamental driver of circulation, tracer transport, and mixing in the middle and upper atmosphere, but their treatment in global circulation models remai…
The transient IDEMIX model as a nonorographic gravity wave parameterization in an atmospheric circulation model
B. Quinn, C. Eden, D. Olbers +2
The Internal wave Dissipation, Energy and Mixing (IDEMIX) model presents a novel way of parameterizing internal gravity waves in the atmosphere. Using a continuous full wave spectr…
Multi-Scale Dynamics of the Interaction Between Waves and Mean Flows: From Nonlinear WKB Theory to Gravity-Wave Parameterizations in Weather and Climate Models
Ulrich Achatz, Young-Ha Kim, Georg Sebastian Voelker
The interaction between small-scale waves and a larger-scale flow can be described by a multi-scale theory that forms the basis for a new class of parameterizations of subgrid-scal…
Crucial Role of Obliquely Propagating Gravity Waves in the Quasi-Biennial Oscillation Dynamics
Young-Ha Kim, Georg S. Voelker, Gergely Bölöni +2
In climate modelling, the reality of simulated flows in the middle atmosphere is largely affected by the model's representation of gravity wave processes that are unresolved, while…
