[HTML][HTML] ICON-Sapphire: simulating the components of the Earth system and their interactions at kilometer and subkilometer scales

C Hohenegger, P Korn, L Linardakis… - Geoscientific Model …, 2023 - gmd.copernicus.org
State-of-the-art Earth system models typically employ grid spacings of O (100 km), which is
too coarse to explicitly resolve main drivers of the flow of energy and matter across the Earth …

Wind power input to ocean near‐inertial waves diagnosed from a 5‐km global coupled atmosphere‐ocean general circulation model

JS von Storch, V Lüschow - Journal of Geophysical Research …, 2023 - Wiley Online Library
Using the 5 km coupled general circulation model ICON, the surface internal wave energy
source, crucial for the oceanic circulation, is quantified as the wind‐induced wave energy …

Discretization of Sea Ice Dynamics in the Tangent Plane to the Sphere by a CD‐Grid‐Type Finite Element

C Mehlmann, O Gutjahr - Journal of Advances in Modeling …, 2022 - Wiley Online Library
We present a new discretization of sea ice dynamics on the sphere. The approach describes
sea ice motion in tangent planes to the sphere. On each triangle of the mesh, the ice …

[HTML][HTML] Accuracy and stability analysis of horizontal discretizations used in unstructured grid ocean models

FR Lapolli, P da Silva Peixoto, P Korn - Ocean Modelling, 2024 - Elsevier
One important tool at our disposal to evaluate the robustness of Global Circulation Models
(GCMs) is to understand the horizontal discretization of the dynamical core under a shallow …

Intensification of daily tropical precipitation extremes from more organized convection

J Bao, B Stevens, L Kluft, C Muller - Science Advances, 2024 - science.org
Tropical precipitation extremes and their changes with surface warming are investigated
using global storm resolving simulations and high-resolution observations. The simulations …

Sensitivity of the Lorenz energy cycle of the global ocean

J Ssebandeke, JS von Storch, N Brüggemann - Ocean Dynamics, 2024 - Springer
We re-examine the Lorenz energy cycle (LEC) for the global ocean by assessing its
sensitivity to model and forcing differences. We do so by comparing LECs derived from two …

Parameterized internal wave mixing in three ocean general circulation models

N Brüggemann, M Losch, P Scholz… - Journal of Advances …, 2024 - Wiley Online Library
The non‐local model of mixing based on internal wave breaking, IDEMIX, is implemented as
an enhancement of a turbulent kinetic energy closure model in three non‐eddy resolving …

Using NIW observations to assess mixed layer parameterizations: A case study in the tropical Atlantic

MA Mrozowska, M Jochum, S Bastin… - Journal of …, 2024 - Wiley Online Library
Tropical sea surface temperature (SST) biases can cause atmospheric biases on global
scales, hence SST needs to be represented well in climate models. A major source of …
