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 ...
