ABSTRACT

A comparison study of four cumulus parameterization schemes (CPSs) , the Anthes-Kuo, Betts-Miller, Grell, and Kain-Fritsch schemes, is conducted using The Pennsylvania State University-National Center for Atmospheric Research mesoscale model. Performance of these CPSs is examined using six precipitation events over the continental United States for both cold and warm seasons. Grid resolutions of 36 and 12 km are chosen to represent current mesoscale research models and future operational ...
