Abstract:
|
As numerical weather forecasts continue to increase their resolution, they have become more informative. To most subjective users, they are superior. However, traditional forecast verification, which aggregates grid-point to grid-point comparisons over an entire grid, often favor the coarser (smoother) scale models. Subsequently, many new approaches have been proposed, many of which have been inter-compared through the Spatial Forecast Verification Methods Inter-Comparison Project (ICP, http://www.rap.ucar.edu/projects/icp). This talk will give an overview of the major new approaches, with emphasis on a technique originating in image analysis, image warping. Further, it will be shown how this technique can potentially be advanced to incorporate space and time in this setting.
