Will high-resolution global ocean models benefit coupled predictions on short-range to climate timescales?

摘要

Highlights?Tangible benefits from increasing ocean resolution towards mesoscale eddy resolving.?Ocean mesoscale variability in boundary current regions impacts the atmosphere.?Coupled feedbacks are important in western boundary current dynamics.?Sub-gridscale parameterisations remain important for all resolutions.?Future research priorities are identified.AbstractAs the importance of the ocean in the weather and climate system is increasingly recognised, operational systems are now moving towards coupled prediction not only for seasonal to climate timescales but also for short-range forecasts. A three-way tension exists between the allocation of computing resources to refine model resolution, the expansion of model complexity/capability, and th
