Resolution dependence of interlinked Southern Ocean biases in global coupled HadGEM3 models Open
The early spinup of the HadGEM3 coupled model displays large-scale biases in the Southern Ocean at an eddy-permitting ocean resolution: the subpolar gyres and Antarctic Slope Current (ASC) are too active, the Antarctic Circumpolar Current …

Towards an improved Antarctic sea-ice representation in HadGEM3-GC5 Open
The historical runs of CMIP6-era coupled climate models generally exhibit negative biases in Antarctic sea ice, as identified across a range of models during the CMIP6 simulations (Roach et al. 2020). The UK's national coupled climate mode…

Interpretation of Net Surface Heat Fluxes and Meridional Overturning Circulations in Global Coupled HadGEM3 Climate Simulations Open
The annual mean net surface heat fluxes (NSHFs) from the ocean to the atmosphere generated by historical forcing simulations using the HadGEM3-GC3.1 coupled climate model are shown to be relatively independent of resolution, for model hori…

Representation of mesoscale in a hierarchy of Met Office ocean model configurations Open
Using an explicit representation or a parametrisation of the ocean mesoscale affects not only the mean state of the ocean but also the climate variability. However, the choice of resolution is constrained by computational costs. Ocean mode…

Using super-residual heat transport to elucidate ocean heat storage in a resolution hierarchy of models Open
The large spread in projections of ocean heat uptake found in CMIP simulations is known to be problematic, leading to large uncertainties in the projected future ocean heat storage. This study introduces a new diagnostic, super-residual tr…

Interpretation of net surface heat fluxes and Meridional Overturning Circulations in global coupled UK-HadGEM3 climate simulations Open
The annual mean net surface heat fluxes (NSHFs) from the ocean to the atmosphere play an important role in driving both atmospheric circulations and oceanic meridional overturning circulations. Those generated by historical forcing simulat…

Assessment of the <i>z</i><sup>∼</sup> Time‐Filtered Arbitrary Lagrangian‐Eulerian Coordinate in a Global Eddy‐Permitting Ocean Model Open
A recognized deficiency of ocean models with a constant‐depth vertical coordinate is for truncation errors in the vertical advection scheme to result in spurious numerical mixing of tracers, which can be substantially stronger than that pr…
