Summary of the 1998 workshop on mesoscale model verification

The major results and discussion items presented at the 1998 Workshop on mesoscale model verification, held 18-19 June in Boulder, Colorado, are summarized. This forum represents perhaps the first attempt to bring together the mesoscale modeling and statistical communities in an attempt to discuss the most challenging issues related to verifying mesoscale forecasts. Pervading discussion was the issue of uncertainty in predictions and observations and how to account for this when performing verification. This article discusses techniques to verify both deterministic and probabilistic predictions and provides recommendations for approaches to future endeavors in mesoscale model verification.
