Abstract/Summary

This document provides a summary of the final report of the Next Generation Ocean Dynamical Core Roadmap Project and recommendations for the way forward: essentially it provides the ‘road map’. To be read alongside the final report, it describes two complementary ways forward for ocean modelling in the UK. First is the incremental evolution of the NEMO model, and second a new modelling initiative drawing on the GungHo project; we make the assumption that the current NEMO code base has a finite competitive life time, and over the course of this review period will ‘lose its edge’ and become increasing inefficient and problematic to use. The key question is then whether this existing code base can be re-factored for future computer architectures or whether a new approach is needed. In this consideration, it is vital to make the distinction between the NEMO code and the NEMO consortium; the latter is seen as a crucial element in UK ocean modelling capability throughout the review period. The Ocean Road Map project has identified two concurrent pathways for ocean model development in the UK: 1. Develop NEMO for global, shelf sea and ‘global coastal ocean’ applications. 2. Develop an ocean model within the GungHo framework. This document largely focuses on the justification for (2), as being the new direction. Further details on (1) for the short- medium term can be found in section 2 and 3 of the final report.
