The Silver Lining of Clustering: Finding Boundaries in the Southern Ocean

Download to your calendar using vCal

If you have a question about this talk, please contact Rachel Furner .

The Southern Ocean is an important component in the global climate system, and some of its dominant features are the deep reaching jets of the Antarctic Circumpolar Current, which we expect to correspond to thermohaline fronts. I used GMM (a soft clustering technique) on a hindcast model of the Southern Ocean. I show that the boundaries between GMM clusters are similar to other definitions of Southern Ocean fronts, with some advantages. This method may be a promising way of turning model data into frontal positions to probe the possible effects of climate change on the Southern Ocean. The talk would aim to be useful for those interested in using clustering on a new data set, or climate model intercomparison. Some of the results are still tentative and I would appreciate robust feedback.
