| ABSTRACT | Interannual variability of Adriatic Deep Water (ADW) formation is studied using an oceanic general circulation model of the Mediterranean Sea driven by realistic (Era-Interim) wind-stress
of 1979–2014. Specifically, the effect of interannual variability of the wind-stress on ADW is isolated by using climatological sea surface temperature and freshwater flux but interannually varying wind-stress. A connection between the wind-stress magnitude over the Rhodes Gyre region and ADW outflow is found in association with the formation of Levantine Intermediate Water (LIW).
Twenty sets of 36 years artificially generated wind-stress anomaly fields were constructed based on the first 50 EOFs of the wind-stress monthly anomalies. These simulations strengthen the connection that was found and reveal a centennial internal variability of both the LIW and the ADW outflow. Our results suggests that freshwater from the North and West Mediterranean compete with the saline LIW coming from the east due to the prominent southward-eastward wind-stress pattern. |
