1 UNIVESRITY OF ATHENS, OCEAN PHYSICS AND MODELING GROUP Monitoring and modeling the Eastern Mediterranean circulation and its climatic variability S. Sofianos and OPAM group EastMed Symposium, November 17-20, 2014 Limassol, CYPRUS

2 POEM contribution in understanding the dynamics of the Eastern Mediterranean was multiple: A coherent picture of the basin circulation and stratification Introduction of spatio-temporal variability Generation scientific and technical capacity to further advance the research Based on these: Regional and/or process oriented studies for understanding the dynamics controlling the circulation and water mass formation New observational and modeling strategies produced new data enabling the investigation at different spatial and temporal scales A variety of modeling tools enabled the investigation of mechanisms controlling the spatial and temporal variability A growing and strengthening monitoring/forecasting system

3 How variable and sensitive are the thermohaline cells of the Eastern Mediterranean? What is the response of the Eastern Mediterranean and its sub-basins to the various mechanisms that are forcing the observed variability? Which are the mechanisms controlling the variability and enhancing the sensitivity of the Eastern Mediterranean thermohaline circulation?

10 Water mass formation variability Annual formation rate (in Sv) of intermediate/dense water in the Aegean (black), sub-basins (blue: north Aeg., green: central Aeg., red: south Aeg.) and Levantine (magenta) for different thresholds. Grey dashed line indicates average value over the period.

11 Atmospheric forcing variability Anomalous winter (NDJF), with respect to reference period, of net heat flux Q0 (in Wm-2), for the periods: pre-emt and , EMT , and post-emt Superimposed anomalous wind stress (scaled in 0.01 N m-2). Negative (positive) values denote loss (gain) for the ocean.

(4) terms in m 2 s -3 ) on the basin buoyancy content evolution, for the Aegean (black) Levantine (magenta) Seas. Negative (positive) values denote loss (gain) for the ocean. Vervatis V. D., S. S.

20 Hotspots of thermohaline circulation variability Transects of Θ( C), S, σθ (kg/m3 ) and oxygen concentration (ml/lt), of 17 CTD stations during the winter of 2006 at the eastern side of the North Central Aegean (NAg CAg); Vervatis, V. D., S. Sofianos, and A. Theocharis, 2011: Distribution of the thermohaline characteristics in the Aegean Sea related to water mass formation processes ( winter surveys), J. Geophys. Res., doi: /2010jc

21 Conclusions: o The Eastern Mediterranean exhibits very large spatio-temporal variability. o The variability and water mass formation processes are related to both surface (mostly heat flux and momentum flux) and lateral forcing (mostly salt flux). o Interbasin exchange changes dramatically the stratification. o Feedback mechanisms are influencing the basin-scale heat and freshwater budget. o Hotspots of deep water formation processes (e.g. eastern-central Aegean). Stratification pattern (mainly due to lateral advection) coincides with areas of intense surface forcing. o Need for synthesizing Thank you!
