To produce a weather forecast we need to model . sea surface temperatures (SSTs) affect atmospheric circulation and precipitation [3], ocean circulation [4] and biogeochemistry [5] determine the flux of carbon between the oceanic and atmospheric reservoirs, and upper ocean temperatures and circulation influence sea ice properties and dynamics, while sea ice also feeds back onto the ocean circulation via insulation and freshwater input. Nature. Popova E, Yool A, Byfield V, et al. Sidorenko D, Goessling HF, Koldunov NV, et al. Coupled Earth system models (ESMs) used to study global climate change include biogeochemistry within their ocean models because of the outsized role of the ocean in the global carbon cycle (e.g., Friedlingstein et al., 2020) and thus the climate system. https://doi.org/10.1175/JPO-D-12-078.1. OMIP contribution to CMIP6: experimental and diagnostic protocol for the physical component of the ocean model intercomparison project. Higher vertical resolution, however, can degrade the solution in z-coordinate models, because it can increase spurious diapycnal mixing in downslope flows [83].

Huang CJ, Qiao F, Dai D. Evaluating CMIP5 simulations of mixed layer depth during summer. The Agulhas eddies pathway is also quite sensitive to the wind stress (relative versus absolute, depending on whether the ocean velocity is considered for the wind stress calculation) in forced simulations [51]. In the other, ESM2G, anindependently developed isopycnal model using the Generalized Ocean Layer Dynamics(GOLD) code base was used. Projections of ocean heat uptake from eddy-rich models are likely to be limited by the length of the spin-up, as the magnitude of the underlying drift is likely to affect stratification and rates of ocean heat uptake [118]. Copyright 1998 - 2023 SciTechDaily. Glob Biogeochem Cycles. 2017;120:12036. We know that all of the models, except probably the Russian models, produce an ensemble of projections that have been running warm compared to reality; the latest, CMIP-6, is running even warmer. Short chemical processes such as pollution from industry and soot from forest fires can have similar effects. The large-scale pattern of SST in ESMs demonstrates errors that are broadly similar across a range of models with cooling in the North Pacific, warming in the Southern Ocean, warming in the Eastern Boundary Upwelling zones, and a patch of very cold water (blue spot) in the North Atlantic [26, 28, 29, 91, 100]. https://doi.org/10.5194/os-13-609-2017. 2015;6:10082. https://doi.org/10.1038/ncomms10082.

Since the first review in 2000 [8], the ocean components of Earth System models (ESMs) have evolved considerably following the different phases of coupled model intercomparison projects, CMIP3 to CMIP5, and most recently CMIP6 [9]. A complete analysis of overflows in HighResMIP ocean models is not yet available for a full assessment of the progress made relative to CMIP5. 2020;13:3643708. Earth Syst Dyn.

Impact of horizontal resolution on the energetics of global ocean-sea-ice model simulations.

Several other studies have also noted multi-decadal temporal variations in ACC transports, of 10 to 30Sv, linked to the occurrence of unrealistic large open-ocean polynya events, in both the Ross and Weddell Sea, which alter the density structure of the Southern Ocean through intense spurious open-ocean convection [85]. An end-to-end model reveals losers and winners in a warming Mediterranean Sea. Evaluation of FESOM2.0 coupled to ECHAM6.3: preindustrial and HighResMIP simulations. Given that a major constraint for running at higher resolutions is the computational cost, some models also exploit variable resolution or nested high-resolution grids [34, 35]. Therefore, modelers have to do what is called parameterize the cloud-energy exchanges. Climate, ecosystems, and planetary futures: The challenge to - Science 2016;98:3650.

On the discretization of the ice thickness distribution in the NEMO3.6-LIM3 global ocean-sea ice model. J Geophys Res submitted. Although ESMs in CMIP6 have evolved in terms of their complexity [26,27,28,29], it is clear that most have retained ocean resolutions which require parameterisation of mesoscale eddies [30] as they fail to resolve the Rossby radius [17, 30].

Predictions of the Earth system, such as weather forecasts and climate projections, require models informed by observations at many levels. This requires further investigation, but such a relationship could arise through either opposing responses to common grid-scale numerics (for example, more damping could result in weaker Gulf Stream transports but stronger ACC transports) or opposing dynamical links (for example, the Gnanadesikan model [99] suggests that a stronger AMOC should act to reduce the density gradients across the ACC, weakening its transport). https://doi.org/10.1175/JPO-D-11-048.1.

Evidence suggests that although the eddy response is not correctly represented in eddy-parameterising models, partial eddy compensation and eddy saturation are obtained in some models in which GM is allowed to vary spatially and temporally [87] and even to some extent with constant GM [98]. In contrast, there are also models submitted to CMIP6 (both DECK and HighResMIP) that employ ocean components of approximately 1/4 degree and 1/10 degree (eddy-present and eddy-rich models). a AMOC and b northward heat transport (NHT) in the Atlantic at 26.5 N. c ACC transport (Sv).

Are you suggesting that we should engage in brain storming to conjecture all the bad things that COULD happen without regard to the probability and then attempt to mitigate them without regard to costs or social consequences?
