<p>In the framework of the Copernicus Marine Environment Monitoring Service (CMEMS) Mediterranean</p><p>Analysis and Forecasting Physical System (MedFS), a specific modeling upgrade has been carried out</p><p>by including the main lunisolar tides.</p><p>Mediterranean tides, even if characterized by small amplitudes, play an important role on the dynamics</p><p>of the Mediterranean sea and the introduction of tides in the hydrodynamic numerical model simulations</p><p>represent the first step in the development of a numerical forecasting model that considers explicitly the</p><p>tidal dynamics and the mesoscales.</p><p>MedFS is an operational system that produces weekly analysis and daily 10-days forecasts of the main</p><p>physical fields with a resolution of around 4.5km over the whole Mediterranean basin including the</p><p>Atlantic Ocean adjacent area (Clementi et al., 2018).</p><p>Baroclinic high resolution numerical experiments have been performed including a tidal potential and</p><p>forcing the model at the Atlantic boundaries with tidal elevation downscaled from a global model</p><p>FES2014 and tidal velocity derived from the TUGOm (http://sirocco.omp.obsmip.</p><p>fr/ocean_models/tugo) ocean hydrodynamic model. The experiments have been carried out</p><p>including the 8 most relevant tidal constituents in the Mediterranean Sea, namely M2, S2, K1, O1, K2,</p><p>N2, P1 and Q1.</p><p>In this work, first results of baroclinic tidal model experiments are presented together with their</p><p>validation with respect to insitu and satellite data as well as comparing with available literature studies.</p><p>In particular the harmonic analysis of tidal amplitudes and phases highlight the model ability to</p><p>correctly represent the tide gauges observations in the whole basin and in the areas of large tidal signal.</p>
