Abstract
The response of the Adriatic Sea to bora wind forcing in stratified conditions is analyzed using a baroclinic multilayer model. The model is linearized in the momentum equations and fully nonlinear in the thermodynamic equations. The model was forced with an idealized wind field having horizontal shear and also convergence. The alongshore shear is approximated by a harmonic function of the alongshore distance with an 80-km space scale, and a maximum corresponding to a moderate wind of 3 dyn cm−2. Idealized initial temperature and salinity vertical profiles similar to an autumn situation are assumed. The model was integrated for five days, presumably a duration of a more persistent bora event. Due to strong shear in the bora wind field the sea level is characterized by a series of highs and lows distributed along the longitudinal axis of the Adriatic. The highest positive sea level departures are observed at the northernmost corner of the Adriatic near Venice associated with the wind setup. The st...
