Future Directions in Basin and Global High-resolution Ocean Modelling

Ocean models are an integral part of today’s ocean and climate research. Over the past decade, there has been increasing use of mesoscale-eddying ocean models for studies of ocean variability on seasonal to decadal timescales, based on the success of forcing products like CORE, DRAKKAR, and JRA55-do. These eddying simulations provide a direct link to observations and serve as a basis for biogeochemical studies. While forced ocean-only models are used for such hindcasts and state estimates, coupled climate models are used to separate internal (natural) variability from external variability and anthropogenic warming trends. To merge the benefits of these different approaches, there is a need for joint evaluation of recent advances in physical processes and numerical methods.

Advances in high-resolution ocean modelling provide opportunities but also challenges for simulating the ocean climate system, particularly with the growing availability of observational measures. A selection of related questions are:

  • How robust is the decadal variability among hindcasts as compared to observational measures?

  • How do modelling strategies regarding spinup, grid resolution (mesoscale to submesoscale), physical parameterizations, and numerical methods affect model drift and robustness of results?

  • Are there additional processes critical to explicitly resolve, such as the submesoscale, internal and surface gravity waves, and tides, along with their feedbacks with the atmosphere and the cryosphere?

  • Is it critical to make the step from ocean-only hindcasts to coupled simulations to separate internal variability from external variability and anthropogenic climate warming?

 

A workshop addressing challenges and future directions in high-resolution ocean modelling will be held in Kiel, Germany, on September 28 - October 1, 2021 hosted by GEOMAR.

 

The aim of this workshop is to address such questions and to provoke further research and collaborations. The focus will be on the realistic representation of the eddying ocean and its interannual to decadal variability in forced basin and/or global ocean-sea ice models as well as in coupled climate models, with the ocean models utilizing spatial resolutions sufficient to admit a vigorous transient mesoscale eddy field. We particularly invite contributions linking observations and reanalysis products with models. Studies furthering the understanding of ocean physics as a driver of biogeochemical processes are also welcome.

During the workshop, we will celebrate the achievements and contributions of Prof. Claus Böning to ocean science and numerical ocean modelling. Claus will retire in autumn 2020.
