Ocean General Circulation Modelling of the Nordic Seas

摘要: The complexity of the state-of-the-art Ocean General Circulation Models (OGCMs) has increased and quality model systems improved considerably over last decades. improvement is caused by a variety factors ranging from representation key physical dynamical processes, parallel development at least three classes OGCM systems, accurate cost-effective numerical schemes, an unprecedented increase in computational resources, availability synoptic, multidecadal atmospheric forcing fields. implications these improvements are that present generation OGCMs can, for first time, complement available ocean observations be used to guide forthcoming observation strategies. also extensively as laboratories assessing cause-relationships observed changes marine climate system, assess how system may change response to, instance, anomalous air-sea fluxes heat, freshwater, momentum. Nordic Seas particularly challenging region because characteristic length scales only few about 10 km, complex interrelated extreme fluxes. This paper gives overview status prognostic modelling system. To exemplify status, we output two widely different systems. We address processes still inadequately described current OGCMs, thus providing guidelines future tailored region.
