Feature tracking on the unit-sphere

By K. I. Hodges

Abstract

Techniques used in a previous study of the objective identification\ud and tracking of meteorological features in model data are extended\ud to the unit sphere. An alternative feature detection scheme is described\ud based on cubic interpolation for the sphere and local maximization.\ud The extension of the tracking technique, used in the previous study,\ud to the unit sphere is described. An example of the application of\ud these techniques to a global relative vorticity field from a model\ud integration are presented and discussed
