A Global Forecast Model Comparison Study - Year 1

Abstract

This report describes the results of the first 15 months of a two- year effort aimed at evaluating the advanced physics global spectral model (APGSM) developed by the Phillips Laboratory, in comparison with the currently operational GSM at Global Weather Central (GWC). Preliminary results from the verification of forecasts from the GWC GSM and APGSM, using the GWC analyses as a reference, are presented. The compaction and analysis of RTNEPH cloud data in preparation for generating and verifying cloud forecasts from the APGSM are described. The development of a cloud forecast scheme based on an application of the cloud curve algorithm to synoptically defined weather regimes is described.
