Simple algorithms to compute meridional overturning and barotropic streamfunctions on unstructured meshes [PDF]
Geoscientific Model Development, 2020 Computation of barotropic and meridional overturning streamfunctions for models formulated on unstructured meshes is commonly preceded by interpolation to a regular mesh.

Sea-ice dynamics on triangular grids [PDF]
Journal of Computational Physics, 2021 We present a stable discretization of sea-ice dynamics on triangular grids that can straightforwardly be coupled to an ocean model on a triangular grid with Arakawa C-type staggering. The approach is based on a nonconforming finite element framework, namely the Crouzeix-Raviart finite element.

Computational modes and grid imprinting on five quasi-uniform spherical C-grids [PDF]
, 2011 Currently, most operational forecasting models use latitude-longitude grids, whose convergence of meridians towards the poles limits parallel scaling. Quasi-uniform grids might avoid this limitation.
