Kurzbeschreibung (Abstract)
A numerical, high resolution integration technique is applied to the hydrodynamic equations on the rotating Earth to study tracer diffusion in homogeneous and stratified lakes. Spatially uniform wind shear is impulsively applied in the long direction of (i) a rectangular basin with constant depth and (ii) Lake Constance. Tracer mass is released at various locations of the free surface and its spreading under the action of diffusion and advection is studied. In homogeneous waters the tracer mass is quickly spread over the entire depth and inertial wave behaviour is discernable inn the concentration profiles; alternatively, for stratified waters the tracer mass is largely confined to that layer into which it is released with Kelvin and/or Poincare wave behaviour superimposed on it.
