Abstract The stratosphere is one of the main potential sources for subseasonal to seasonal predictability in midlatitudes in winter. The ability of an atmospheric model to realistically simulate the stratospheric dynamics is essential in order to mov

Parameterizations of subgrid-scale gravity waves (GWs) in atmospheric models commonly involve the description of the dissipation of GWs. Where they dissipate, GWs have an increased effect on the large-scale flow. Instabilities that trigger wave break

Using a 3-dimensional (3D) Lagrangian ray-tracing approach, a realistic gravity-wave (GW) parameterization has been developed: Multi-Scale Gravity Wave Model (MS-GWaM). It is a unique and useful tool to simulate and study the 3D transient dynamics of

Internal gravity waves (IGWs) are important distributors of energy and momentum in a stratified atmosphere. While most IGWs are presumably excited at lower altitudes their effects are most important between the upper troposphere and the mesopause (~8

This article describes the implementation of grid refinement in the ICOsahedral Nonhydrostatic (ICON) modeling system. It basically follows the classical two-way-nesting approach known from widely used mesoscale models like MM5 or WRF, but differs in

Weather prediction centers are always looking for the best computational performance for their numerical weather prediction (NWP) model, given their financial budget. Over the last decades, most centers relied on computer systems with scalar x86 arch

Warm-rain orographic precipitation at an isolated mountain is studied by numerical experiments using the non-hydrostatic COSMO model. The simulations are analyzed to derive scaling relations for the precipitation efficiency as a function of the relev
