Diagnostic and Forecast Graphics Products at NMC Using High Frequency Model Output

Abstract

Archived hourly output from the National Meteorological Center (NMC) prediction models has provided the basis for advanced graphic diagnostic and forecast tools. The high-frequency data are available on a regional selected station network. Each point in the network consists of the basic state variables at each sigma layer and a variety of surface quantities. Five graphics products have been developed at NMC to display the hourly forecast data. They are thermo-dynamic diagrams, standard format meteograms, extended format meteograms, station model plots, and contoured analyses. Graphics workstation animation capabilities enhance the products? value. Dissemination of a portion of the raw data by the Automation of Field Operations and Services (AFOS) is underway.
