Abstract: The Energy Exascale Earth System Model (E3SM) is a new coupled Earth system model sponsored by the U.S Department of Energy. Here we present E3SM global simulations using active ocean and sea ice that are driven by the Coordinated Ocean‐ice Reference Experiments II (CORE‐II) interannual atmospheric forcing data set. The E3SM ocean and sea ice components are MPAS‐Ocean and MPAS‐Seaice, which use the Model for Prediction Across Scales (MPAS) framework and run on unstructured horizontal meshes. For this study, gr… Show more

“…MPAS‐Ocean, based on the MPAS framework (Ringler et al, ), is the ocean component of E3SMv1 (Petersen et al ). MPAS‐Ocean uses a mimetic finite volume discretization of the primitive equations and invokes the hydrostatic, incompressible, and Boussinesq approximations on a staggered C‐grid (Arakawa & Lamb, ; Ringler et al, ; Thuburn et al, ).…”

“…Ocean and sea ice components in E3SMv1 are based on the Model for Prediction Across Scales (MPAS; Petersen et al, ; Ringler et al, ). For the high‐resolution simulations presented here, the Gent‐McWilliams (GM) mesoscale eddy parameterization is not needed and is disabled.…”

“…respectively, where Δx is the horizontal grid cell width. The coefficients were tuned in Petersen et al (2019) to be as small as possible, while ensuring that dissipation is sufficient for stability and to prevent grid scale noise. The addition of hyperviscosity removes energy more strongly at the highest wave numbers and allows a smaller viscosity coefficient.…”

“…This paper documents the use of JIGSAW (Engwirda, 2017) to produce optimized spherical Voronoi/Delaunay meshes for use with MPAS. MPAS-Ocean and MPAS-Sea Ice are components of the Department of Energy's Energy Exascale Earth System Model (E3SM) (https://e3sm.org) (Golaz et al, 2019;Petersen et al, 2019). An ensemble of horizontal meshes was investigated using the Coastal United States "Plus" (CUSP) configuration, which is designed to enhance the resolution of coastal regions of North and Central America plus Hawaii.…”
