| Zusammenfassung |
| The North-Western Mediterranean Sea is a key location where intense air-sea exchanges
occur, especially during winter when the succession of strong northerly and north-westerly
wind boosts the dense water formation. The second Special Observation Period (SOP2) of the
HyMeX program, which took place between 1st February and 15th March 2013, was
dedicated to the observation of the dense water formation and ocean deep convection
processes. During this period, several platforms sampled the area, providing a unique
dataset to better identify the coupled processes leading to dense water formation.
This study investigates the impacts of the fine scale ocean-atmosphere coupled
processes on dense water formation during winter 2012-2013. We developed the
coupling between the NEMO-WMED36 ocean model (1/36∘ resolution) and the
AROME-WMED numerical weather prediction model (2.5 km resolution) and ran the
high-resolution air-sea coupled system over SOP2. The coupled simulation is compared to an
ocean-only simulation forced by AROME-WMED operational forecasts and to
air-sea observations collected during the HyMeX SOP2. The results show small
differences in term of surface fluxes. Dense water formation is slightly changed in the
coupled simulation, whereas fine-scale ocean processes are significantly modified. |
