A Constrained Spectral Approximation of Subgrid-Scale Orography on Unstructured Grids
Ray Chew, Stamen Dolaptchiev, Maja-Sophie Wedel +1
The representation of subgrid-scale orography is a challenge in the physical parameterization of orographic gravity-wave sources in weather forecasting. A significant hurdle is enc…
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…
Interactions between gravity waves and cirrus clouds: asymptotic modeling of wave induced ice nucleation
Stamen I. Dolaptchiev, Peter Spichtinger, Manuel Baumgartner +1
We present an asymptotic approach for the systematic investigation of the effect of gravity waves (GW) on ice clouds formed through homogeneous nucleation. In particular, we consid…
Stochastic Parameterization: Towards a new view of Weather and Climate Models
Judith Berner, Ulrich Achatz, Lauriane Batte +23
The last decade has seen the success of stochastic parameterizations in short-term, medium-range and seasonal forecasts: operational weather centers now routinely use stochastic pa…
