| Zusammenfassung |
| Results from the spectral analyses of the flows in two experiments where
turbulent flows were generated in a rotating tank with topographic β-effect, are presented.
The flows were forced either by heating water from below or supplying fresh water at the top of saline layer. The flow was
essentially barotropic in the first experiment and baroclinic in the second
experiment. The gradient of the surface elevation was measured using optical
altimetry (Altimetric Imaging Velocimetry). Multiple zonal jets of
alternating direction were observed in both experiments. Turbulent cascades
of energy exhibit certain universal properties in spite of the different
nature of flows in the experiments. |
