Sensitivity of the basin-scale internal wave structure in a prealpine lake to wind distribution

Wind distribution plays a fundamental role in lake dynamics, but its representation is a challenging task in alpine areas due to the strong influence of the topography on the wind regime. We propose to couple an high resolution meteorological model to a 3D hydrodynamic model to simulate the basinscale internal wave structure in Lake Iseo. The improved distributed description of the wind stress over the lake surface leads to a significant enhancement of the representation of the main basin-scale internal wave motion.
