“…POM has been applied extensively to the Mediterranean and the Strait of Gibraltar (e.g. Zavatarelli and Mellor, 1995;Ahumada and Cruzado, 2007;Jungclaus and Mellor, 2000;Drakopoulos and Lascaratos, 1999;Alhammoud et al, 2010;Sannino et al, 2002;Beckers et al, 2002). In an application to the Mediterranean, POM is set up with a true evaporation instead of a virtual salt flux.…”

Abstract. A high-resolution parallel ocean model is set up to examine how the sill depth of the Atlantic connection affects circulation and water characteristics in the MediterraneanBasin. An analysis of the model performance, comparing model results with observations of the present-day Mediterranean, demonstrates its ability to reproduce observed water characteristics and circulation (including deep water formation). A series of experiments with different sill depths in the Atlantic-Mediterranean connection is used to assess the sensitivity of Mediterranean circulation and water characteristics to sill depth. Basin-averaged water salinity and, to a lesser degree, temperature rise when the sill depth is shallower and exchange with the Atlantic is lower. Lateral and interbasinal differences in the Mediterranean are, however, largely unchanged. The strength of the upper overturning cell in the western basin is proportional to the magnitude of the exchange with the Atlantic, and hence to sill depth. Overturning in the eastern basin and deep water formation in both basins, on the contrary, are little affected by the sill depth.The model results are used to interpret the sedimentary record of the Late Miocene preceding and during the Messinian Salinity Crisis. In the western basin, a correlation exists between sill depth and rate of refreshment of deep water. On the other hand, because sill depth has little effect on the overturning and deep water formation in the eastern basin, the model results do not support the notion that restriction of the Atlantic-Mediterranean connection may cause lower oxygenation of deep water in the eastern basin. However, this discrepancy may be due to simplifications in the surface forcing and the use of a bathymetry different from that in the Late Miocene. We also tentatively conclude that blocked outflow, as found in experiments with a sill depth ≤ 10 m, is a plausible scenario for the second stage of the Messinian Salinity Crisis during which halite was rapidly accumulated in the Mediterranean.With the model setup and experiments, a basis has been established for future work on the sensitivity of Mediterranean circulation to changes in (palaeo-)bathymetry and external forcings.

“…POM has been extensively described in the literature Mellor, 1983, 1987;Oey et al, 1985a, b;Galperin and Mellor, 1990a, b;Ezer, 1991, Horton et al, 1997;Lascaratos and Nittis, 1998) and is accompanied by a comprehensive user's guide (Mellor, 1998). It has been used previously in numerous coastal applications like the South Atlantic Bight (Blumberg and Mellor, 1983), Delaware Bay (Galperin and Mellor, 1990a, b), the Gulf of Mexico (Mellor and Blumberg, 1985), the Gulf Stream (Ezer and Mellor, 1992), the Mediterranean Sea (Zavatarelli and Mellor, 1995;Horton et al, 1997;Drakopoulos and Lascaratos, 1997), the Adriatic Sea (Zavatarelli and Pinardi, 1995) and the Levantine Sea (Lascaratos and Nittis, 1998), to list some of them. The model has a bottom-following vertical sigma coordinate system, a free surface and a split mode time step.…”

A one-way nested eddy resolving model of the Aegean and Levantine basins: implementation and climatological runs

2003

View full text Add to dashboard Cite

Abstract. The present study deals with the implementation of an eddy resolving model of the Levantine and Aegean basins and its one-way nesting with a coarse resolution (1/8 • × 1/8 • ) global Mediterranean general circulation model. The modelling effort is done within the framework of the Mediterranean Forecasting System Pilot Project as an initiative towards real-time forecasting within the eastern Mediterranean region.The performed climatological runs of the nested model have shown very promising results on the ability of the model to capture correctly the complex dynamics of the area and at the same time to demonstrate the skill and robustness of the nesting technique applied.A second aim of this study is to prepare a comprehensive climatological surface boundary conditions data set for the Mediterranean Sea. This data set has been developed within the framework of the same research project and is suitable for use in ocean circulation models of the Mediterranean Sea or parts of it. The computation is based on the ECMWF 6-h atmospheric parameters for the period 1979-1993 and a calibrated set of momentum and heat flux bulk formulae resulted from previous studies for the Mediterranean region.

“…In the last years, the Mediterranean Sea has been subject to several numerical modeling works focused mainly on the study of the circulation and mechanisms that generate it at different temporal and spatial scales (Menzin and Moskalenko, 1982;Heburn, 1987;Bergamasco, 1989, 1991;Stanev et al, 1989;Beckers, 1991;Tziperman and Malanotte-Rizzoli, 1991;Bergamasco et al, 1993;Pinardi and Navarra, 1993;Alvarez et al, 1994;Haines and Wu, 1995;Roussenov et al, 1995;Zavatarelli and Mellor, 1995;Herbaut et al, 1996;Wu and Haines, 1996;Herbaut et al, 1997;Brankart and Brasseur, 1998;Castellari et al, 1998;Drakopoulos and Lascaratos, 1999;Bergamasco et al, 1999;Pinardi and Masetti, 2000;Beckers et al, 2002;Demirov and Pinardi, 2002;Molcard et al, 2002;Zavatarelli et al, 2002;Brenner, 2003;Echevin et al, 2003;Korres and Lascaratos, 2003;Sorgente et al, 2003;Tonani, 2003;Zavatarelli and Pinardi, 2003;Fernández et al, 2005;Jordà, 2005;and others). Nevertheless, the variety of models, configurations, parameterizations, resolutions, forcing, etc., found in the literature on numerical modeling of the Mediterranean Sea circulation, in some way, suggest that no single model is going to be the best one for all applications.…”

Abstract. The Princeton Ocean Model -POM (Blumberg and Mellor, 1987) has been implemented in the Northwestern Mediterranean nested (in one-way off-line mode) to a general circulation model of the Mediterranean Sea -OGCM (Pinardi and Masetti, 2000;Demirov and Pinardi, 2002) in order to investigate if this model configuration is capable of reproducing the major features of the circulation as known from observations and to improve what has been made by previous numerical modeling works. According to the model results, the large-scale cyclonic circulation in the northern part of the Northwestern Mediterranean is, at least in the upper layers, less coherent in winter and spring than in summer and autumn. Furthermore, there is evidence that the mesoscale structure (eddies and meanders) is, during all year, a significant dynamic characteristic in this region of the Mediterranean Sea. Finally, concerning the circulation in the lower layers, the model results have confirmed that Levantine Intermediate Water (LIW) and Western Mediterranean Deep Water (WMDW) follow essentially a cyclonic path during all year.
