Description:

A seasonal evaluation of Spectral Medium-Range Forecast Model (MRF) 500mb forecast performance, over the hemispheres between 20 and 80 degrees, is summarized for the period from December 1981 to November 1990; at the start of the verification period, the Spectral model had 12 vertical layers and a rhomboidal 30 mode horizontal resolution. Initialized fields are used as the verifying field. Climate Analysis Center (CAC) archived forecast and climatological data, based on 1978-85 means, are used; note that archived data are limited to 12 modes and all years are evaluated with the current climatology. Dr. Steve Tracton, CAC, provided the verification program. A brief discussion of anomaly correlation coefficient scores and potential skill levels is given.
