We present results of various circulationscenarios for the wind-induced three-dimensional currents in Lake Constance,obtained with the aid of a semi-spectral semi-implicit finite difference codedeveloped in Haidvogel et al. and Wang and Hutter. Internal Kelvinand Poincaré-type oscillations are demonstrated in the numerical results, whoseperiods depend upon the stratification and the geometry of the basin and agreewell with measured data. By solving the eigenvalue problem of the linearizedshallow water equations in the two-layered stratified Lake Constance, theinterpretation of the oscillations as Kelvin and Poincaré-type waves iscorroborated.Key words: Oceanography: general (limnology; numericalmodeling) – Oceanography: physical (internal and inertial waves)
