Abstract

Deep convection in the northwestern Mediterranean Sea is studied using COAMPS for winters 1998/1999 and 1999/2000. Hourly surface forcing from COAMPS atmospheric reanalyses are applied to the Navy Coastal Ocean Model (NCOM). Numerical studies have investigated the ocean response to the stronger Mistral year (1998/1999) and weaker Mistral year (1999/2000). Large differences in deep convection between the two winters are also investigated by analyzing the depth and temperature of the mixed-layer, the surface height, and the current structure. Interaction between local deep convection and advected Levantine Intermediate Water (LIW) is also presented in the simulated results.
