SUMMARY: The Silver Lining of Clustering: Finding Boundaries in the Southe
 rn Ocean - Simon Thomas (BAS)

DESCRIPTION:The Southern Ocean is an important component in the global cli
 mate system\, and some of its dominant features are the deep reaching jets
  of the Antarctic Circumpolar Current\, which we expect to correspond to t
 hermohaline fronts. I used GMM (a soft clustering technique) on\na hindcas
 t model of the Southern Ocean. I show that the boundaries between GMM clus
 ters 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 us
 ing clustering on a new data set\, or climate model intercomparison. Some 
 of the results are still tentative and I would appreciate robust feedback.
