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…
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…
Instability cascade of strongly nonlinear gravity waves in a vertically sheared atmosphere
Georg Sebastian Voelker, Mark Schlutow
Although internal gravity waves are generally recognized as an important mechanism to distribute energy through the atmosphere, their dynamics near the instability is only partiall…
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…
MS-GWaM: A 3-dimensional transient gravity wave parametrization for atmospheric models
Georg S. Voelker, Gergely Bölöni, Young-Ha Kim +2
Parametrizations for internal gravity waves in atmospheric models are traditionally subject to a number of simplifications. Most notably, they rely on both neglecting wave propagat…
On strongly nonlinear gravity waves in a vertically sheared atmosphere, Part I: Spectral stability of the refracted wave
Mark Schlutow, Georg S. Völker
We investigate strongly nonlinear stationary gravity waves which experience refraction due to a thin vertical shear layer of horizontal background wind. The velocity amplitude of t…
