Abstract:

Parameteterizations for global models have been in use and (simultaneously) under development for more than fifty years. Today’s fastest computers are beginning to make it possible to eliminate some parameterizations. In this talk, I will argue that parameterizations have conceptual value that goes beyond their practical applications. I will lay out current issues in parameterization, and outline a new approach that addresses those issues.
