Abstract : This poster outlines an initiative to bring together the world-wide leading researchers actively contributing to the development of oceanic model dynamical cores irrespective of target applications (regional, coastal, or global). The first community for the numerical modeling ofthe global, regional and coastal ocean (COMMODORE) workshop ( has been organized in Paris in September 2018 [1]. In total, the participants represented 15 oceanic dynamical cores among the most widely used by the research and operational community. The present poster summarizes the challenges and prospects for oceanic numerical cores across all scales discussed during the workshop. In particular, identified challenges to be addressed include strategies for multi-resolution, energy consistency and resolved/unresolved scales coupling, the design of vertical coordinates and their link with spurious numerical mixing, the inclusion of non-hydrostatic pressure contribution within existing primitive equations models, and the proper treatment of wetting and drying.
