CURRENT AND RECENT ACTIVITIES AND INTERESTS

1. CLIMATE DYNAMICS ON THE DECADAL TIME SCALE

This work is based on the examination of reanalysis and satellite-based rainfall data, coupled with dynamical interpretations. Efforts so far have been focussed on the late 1960s climate shift that influenced (among many other places) southwest Western Australia. Recent work has focussed on the nature of El Nino and the classification of different types of ENSO events. Present efforts are directed toward the causes of more recent droughts, and the links between rainfall and dynamics.

2. THE DYNAMICS AND MIXING OF DOWNSLOPE FLOWS

The main results of this work to date are described in references 110, 114 and 121. Observations of dense downslope flows into stratified environments show that mixing with the environment may occur in a variety of different ways, depending on the Buoyancy number, the bottom slope, and the bottom drag. Some characteristic phenomena observed in these experiments are: Holmboe waves , turbulent plumes , and, under certain conditions, a most unusual double outflow double outflow . Some movie examples are shown in the following short videos. These show dense fluid marked by fluorescine dye, flowing down a slope into a salt-stratified environment. Some of these results are being incorporated into a model of the Antarctic Slope Front.
