Abstract: The amplitude and phase of a topographically forced wave in a baroclinic flow are studied both experimentally and theoretically. The experiments were conducted in a thermally driven fluid in a rotating annulus with two-wave ...

Abstract: Empirical evidence is presented to the effect that amplitude vacillation in a thermally driven rotating annulus of fluid is due primarily to the interference of two modes with the same azimuthal wavenumber and different ...

Abstract: Relationships are examined among radial eddy fluxes of heat, eddy temperature variances and basic-state temperature parameters (e.g., radial gradients and variances of the azimuthally averaged temperature) over a broad ...

Abstract: The characteristics of amplitude vacillation, structural vacillation and geostrophic turbulence in two thermally driven rotating fluids with different viscosities are investigated. The data presented correspond to experiments ...

Abstract: Rotating annulus experiments are described in which the imposed thermal forcing is varied periodically by means of cyclic variations of the cold inner-bath temperature. In the way of background the results of conventional ...

Abstract: A series of laboratory experiments was performed in a thermally-driven rotating annulus of fluid with and without two-wave bottom topography. Velocity measurements were made by illuminating a thin layer of fluid at mid-depth ...

Abstract: Complex principal component analysis is applied to data from three laboratory experiments of flow over two-wave sinusoidal bottom topography in a thermally driven, rotating annulus of fluid. The experiments are conducted ...
