Imbrication d'un modèle de circulation des eaux prés des cotes Tunisiennes dans un modèle de circulation de la mer Méditerranée

Abstract

The present work aims at nesting a regional ocean model near the Tunisia coasts in a general circulation model of the Mediterranean Sea. The grid of the Tunisia coasts model includes a zooming option that permits the resolution increase in a given area. Initial conditions are obtained by the interpolation of the outputs provided by the regular grid model. The stretched model needs more computing time than the regular resolution one. But tests performed with this model have shown that a 20-day simulation is sufficient to reach a dynamical equilibrium. The stretched model reproduced efficiently the water circulation and characteristics in the Gulf of Gabes.
