Through an NSF funded collaboration with Jenni Evans (Meteorology, PSU), I also work on the application of dimension reduction, clustering, regression and re-sampling methods to large-scale meteorological data. In particular, we investigate the structure and lifecycle evolution of cyclones with a focus on the process of extra-tropical transition.
