The Boundary Layer Dispersion and Footprint Model: A fast numerical solver of the Eulerian steady-state advection-diffusion equation
Mark Schlutow, Ray Chew, Mathias Göckede
Understanding how greenhouse gases and pollutants move through the atmosphere is essential for predicting and mitigating their effects. We present a novel atmospheric dispersion an…

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…

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…
