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 impact of transience in the interaction between orographic gravity waves and mean flow
Felix Jochum, Ray Chew, François Lott +3
A Lagrangian gravity-wave parameterization (MS-GWaM, Multi-Scale Gravity-Wave Model) that allows for fully transient wave-mean-flow interaction and horizontal propagation is applie…
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…
