NCEP Service Center Evaluations HPC Pete Manousos

Real-Time Parallel Run Subjective Evaluation: HPC compared the 21 member SREF and the operational 15 member SREF over the 4 week period Nov 1 – 28 2005. We did not note any significant differences in phase or amplitude in mean mass fields – nor significant differences in QPF. Careful scrutiny revealed the spread from the 21 Member SREF tended to be a bit greater than the operational SREF, but this had no operational impact.
NOTE ! HPC was very disappointed in the web interface to evaluate the output (see below).
