Description:

"Beginning with data for September 1981, a systematic verification program has been run by Mark Rozwodoski to diagnose, on a monthly basis, the zonal average, temperature forecast errors committed by the NMC, large-scale prediction model. The operational analysis (Hough) is used as a reference. The mean and standard deviation statistics are computed for the twelve mandatory pressures (1000 - 50 mb) for forecasts of length 24, 48, 60, and 72 hours. For the longer range forecasts (out to 192 hours), only four pressure levels are verified, viz: 1000, 850, 500, and 250 mbs. In addition, to the forecast statistics, the mean and standard deviation of the verifying (monthly mean) analysis is also computed"--Introduction.
