During this week, Viena is celebrating the research in Ocean Sciences in the European Geosciences Union General Assembly (EGU) 2018. 

In this frame, a talk about the SOCIB Western Mediterranean circulation model will explain the impacts of downscaling the CMEMS (the Copernicus Marine Environment Monitoring Service) Mediterranean model to represent the fine scales associated with the mesoscale variability and coastal processes. This talk will be given by Eva Aguiar, of the MEDCLIC program, next Friday the 13th of April. 

The research focuses on the impact of downscaling the CMEMS Mediterranean model over the Western basin. This is evaluated using the high resolution Western Mediterranean Operational model (WMOP, ∼2km spatial resolution) developed at SOCIB, the Balearic Islands Coastal Observing and Forecasting System. WMOP uses the larger scale CMEMS Med model (v02, ∼6km resolution) as initial and boundary conditions. Downscaling effects are assessed considering in particular 1) the mean surface spatial flows over three strategic areas monitored with High Frequency Radars (HFR), and 2) the spatial distribution, number, size and lifetime of mesoscale eddies. The model evaluations as well as the quantification of the impacts of downscaling are achieved through a multi-platform perspective which includes high-resolution surface currents observations from HFR, glider transports across a key-section, and satellite altimetry data.

The Mediterranean Sea is often considered as a small scale ocean laboratory where energetic eddies, fronts and circulation features have important ecological consequences. Downscaling the CMEMS Mediterranean model over a reduced area allows to reproduce the fine scale variability and coastal processes with a higher resolution, and the interactions between mean flows and mesoscale eddies in particular.

WMOP: a high-resolution numerical model nested in the CMEMS Mediterranean model (CMEMS Med Rea)

A better understanding of ocean variability and ecosystems’ response requires the coordination of a continuous and long-term system of ocean observation at different scales and covering from the nearshore to the open ocean. In particular, it is necessary to anticipate the adaptation to the evolution of the climate of our planet and to preserve healthy and sustainable oceans for future generations. 

The research has been carried out by SOCIB (1) and IMEDEA (2) members (Eva Aguiar (1), Baptiste Mourre (1), Emma Reyes (1), Jaime Hernandez-Lasheras (1), Emma Heslop (1), Melanie Juza (1), Evan Mason (2), Joaquin Tintore (1, 2) as the result of collaboration between these public institutions.
