“…From November to May, the isohalines appear inclined towards the African side. The MAW flows eastward, predominantly along the Tunisian side with speeds reaching up to 30 cm/s, in agreement with calculations by Horton et al (1997b). The maximum simulated velocity is reached in November with speeds up to 50 cm/s.…”

Abstract.A high resolution eddy-resolving primitive equation numerical model, based on the Princeton Ocean Model (POM), is used to study the seasonal variability of the general circulation in the Central Mediterranean Sea. The model is run on a seasonal cycle, perpetual year simulation for five years, with nesting to the coarser resolution Ocean General Circulation Model (OGCM), covering the whole Mediterranean Sea. The model results are compared to the current knowledge on the hydrography and dynamics of the area, with a special focus on the annual cycle of the Modified Atlantic Water (MAW), on the circulation in the Sardinia Channel, the water exchange across the Strait of Sicily, and on the transition and fate of the Levantine Intermediate Water (LIW). The results show that the adopted coupling techniques between the two models give a proficient downscaling of the large-scale OGCM flow field into the regional scale model. The numerical solution is also used to highlight the seasonal characteristics of important dynamical features in the area, as well as to shed light on the scarcely known circulation regimes along the north African shelf and slope.

“…odu.edu/POMWEB/) with numerous applications both for ocean and regional modeling studies. POM has been implemented in the Mediterranean Sea at basin/sub-basin scale (Zavatarelli and Mellor, 1995;Horton et al, 1997;Korres and Lascaratos, 2003, among others) and also on regional studies, including the Aegean Sea (Korres et al, 2010;Androulidakis et al, 2012;among others). It is a primitive equation, sigma coordinate and free surface elevation model that employes a 2.5 turbulence closure scheme (Mellor and Yamada, 1982) for vertical mixing.…”

Modeling the Fate and Distribution of Floating Litter Particles in the Aegean Sea (E. Mediterranean)

et al. 2017

A circulation model is coupled to a Lagrangian particle-tracking model to simulate the transport floating litter particles in the Aegean Sea, Greece (Eastern Mediterranean). Considering different source regions and release dates, simulations were carried out to explore the fate and distribution of floating litter over 1990-2009, taking into account the seasonal and interannual variability of surface circulation. Model results depicted recurrently high concentrations of floating litter particles in the North Aegean plateau, the Saronikos Gulf, and along Evia and Crete islands. Modeled transport pathways of floating litter demonstrated that source regions are interconnected, with Saronikos Gulf being a main receptor of litter from other sources. Notably higher percent of litter exit (∼35%) than enter the model domain (∼7%) signified that Aegean Sea seems to act as a source rather than receptor of floating litter pollution in the Eastern Mediterranean Sea. Beached litter was found around 10%, mostly located in the western part of the Aegean Sea. This is the first modeling study to explore the transport of floating marine litter in Greek waters.

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.
