Wind curl vs variable eddy viscosity: A Northern Adriatic related modelling study

Abstract

The influence of different magnitudes of the vertically constant eddy viscosity, as well as heterogeneity in the wind field, on the wind induced motions in the Northern Adriatic has been considered in several recent modelling studies. Those studies, incorporating partial field data verification, have suggested several lines of improving the Northern Adriatic model predictions, among them more adequate treatment of the vertical eddy viscosity. This paper presents preliminary results of the Northern Adriatic model that allows for the vertical variable eddy viscosity. The results indicate an improvement in current field prediction which has been called for by previous model to data comparisons.
