Volume and heat transports in the world oceans from an ocean general circulation model

Abstract: ABSTRACT.Monitoring the volume and heat transports around the world oceans is of fundamental importance in the study of the climate system, its variability, and possible changes. The application of an Oceanic General Circulation Model for climatic studies needs that its dynamic and thermodynamic fields are in equilibrium. The time spent by the model to reach this equilibrium is called spin-up time. This work presents some results obtained from the application of the Modular Ocean Model version 4.0 initialized … Show more

“…Transport through Drake Passage weakens rapidly from an initial value of > 160 Sv, and from the year 200 it settles around 110-115 Sv. This is lower than the recent observation-based estimate of 173 Sv (Donohue et al, 2016) or previous estimated values of around 130-140 Sv (e.g. Cunningham et al, 2003) but within the range seen in other coupled climate models (Beadling et al, 2020).…”

“…The method to compute climatological Lagrangian coherent structures (cLCS) was developed recently by Duran et al 26 and has been used to extract important Lagrangian transport patterns from large velocity time series. Pattern identification include (1) isolated regions where trajectories are unlikely to leave or enter; (2) regions that attract nearby parcels of water and therefore are more susceptible to pollution impacts; and (3) recurrent transport patterns. Some recent studies have shown the relevance of cLCS.…”

“…Globally, the OHT reaches 1.4 PW, instead of the 2.1 ± 0.3 PW computed by Trenberth and Caron (2001). Over the Southern Ocean (35-65°S) OHT is northward, a characteristic seen previously in MOM-based ocean models (de Freitas Assad et al, 2009). This may be related to the strong warm SST bias present over region 40-60°S ( Fig.…”
