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 annulus experiments, in which the imposed temperature contrast is not varied, and of hysteresis experiments, in which the imposed temperature contrast is varied slowly enough to be considered quasi-static, are reviewed. It is found that, in the region of dimensionless parameter space in which our experiments were conducted, the flow configuration in conventional and hysteresis experiments is determinate in the sense that it depends only upon the point in dimensionless-parameter space at which the experiment is conducted and the direction from which this point is approached. The flow configuration in experiments in which the imposed temperature contrast is varied in a cyclic fashion is found to be indeterminate in the sense that it changes from one state to another sporadically and cannot be predicted solely as a function of season.
