Abstract

A simple model of the Antarctic Ocean has been built in order to study the dynamical effects of transverse ridges on the circumpolar oceanic flow. By covering a wide range of model shapes and sizes and by varying the rotation rates of both the fluid container and the plate that drives the interior flow, we have uncovered certain dimensionless parameters that appear to govern the basic flow patterns and volume flux. The effect of combining several topographic features is also explored in a preliminary experiment.

Zusammenfassung

Zur Untersuchung des dynamischen Effektes von transversalen Erhebungen auf die Strömung um die Antarktis wurde ein einfaches Modell des antarktischen Ozeans gebaut. Durch Variation von Modellgrösse und Form sowie der Rotationsgeschwindigkeiten war es möglich dimensionslose Parameter zu finden, welche die Strömungsformen und den Volumenstrom bestimmen. Auch der kombinierte Einfluss von mehreren topographischen Erhebungen wurde kurz untersucht.

It is with the greatest pleasure that I dedicate this paper to Professor Nicholas Rott on the occasion of his 60th birthday. As a much admired colleague and friend he has been a source of inspiration for many years and I hope to be able to celebrate in similar fashion in coming decades.
