Abstract: Focused research through ocean, wave and atmospheric science disciplines will improve the representation of momentum exchange across the ocean-atmosphere interface in regional ocean prediction systems.
This study objectives are:
• Improve the consistency of ocean and wave prediction systems within CMEMS between those derived from either “forced”, partially or fully “coupled” modes,
• Examine the sensitivity of ocean-wave-atmosphere feedbacks to model physics and system resolution choices,
• Demonstrate the value of providing CMEMS products from ocean-wave systems that are fully coupled with an atmospheric component relative to those running in forced mode.
This project will deliver technical developments to NEMO interface routines and case study evaluations focused on the North-West Shelf. The research builds on unique modelling capability and a fully self-consistent and flexible evaluation framework with which to run traceable experiments. Following this work the CMEMS community will have available an enhanced ocean model infrastructure and demonstration of a more robust methodology for assessing forced and fully coupled prediction systems. Improved understanding and evidence of the impacts of closer coupling will be delivered. These will inform future system configuration choices.
Developments will readily translate into CMEMS service evolution across MFCs, improving the quality of information provided to users.
