, In oceanografia e climatologia un modello … In oceanografia e climatologia un modello generale della circolazione oceanica (abbreviato in OGCM, dall'acronimo della terminologia in inglese Ocean General Circulation Model) è un particolare tipo di modello generale della circolazione che descrive i processi fisici e termodinamici che avvengono negli oceani e che include tutti i maggiori parametri che influenzano la circolazione oceanica generale. La circolazione oceanica generale è definita su scala spaziale e temporale superiore alla mesoscala, cioè dell'ordine dei 100 km e 6 mesi. Questi modelli descrivono gli oceani attraverso l'utilizzo di una griglia tridimensionale che include parametri termodinamici attivi; sono pertanto i più direttamente applicabili agli studi climatici e rappresentano perciò gli strumenti più avanzati attualmente disponibili per simulare la risposta del sistema oceanico globale alla crescente concentrazione di gas ad effetto serra. È stata sviluppata una gerarchia di modelli OGCM che includono vari gradi di copertura spaziale, risoluzione, realismo geografico, processi e così via. realismo geografico, processi e così via.

The oceanic general circulation is defined as the horizontal space scale and time scale larger than mesoscale (of order 100 km and 6 months). They depict oceans using a three-dimensional grid that include active thermodynamics and hence are most directly applicable to climate studies. They are the most advanced tools currently available for simulating the response of the global ocean system to increasing greenhouse gas concentrations. A hierarchy of OGCMs have been developed that include varying degrees of spatial coverage, resolution, geographical realism, process detail, etc.geographical realism, process detail, etc.
