Verification of CSU WRF and NCEP model forecasts: 500-mb height, May 2012
Switch to current verification statistics
-- Forecasts are verified against the NCEP NAM analysis on the 212 (40-km) grid. For verification against radiosonde observations, click here.
-- BCRMSE = Bias-corrected root mean square error. Reflects the forecast errors not associated with the bias. Lower numbers are better.
-- RMSE = Root mean square error. Lower numbers are better.
-- Bias = Difference between the average forecast height and the average observed height. A value of zero reflects an unbiased forecast.
-- The second-from-bottom graph compares the area-averaged ensemble spread against the BCRMSE. In the long run, these should be approximately equal for a well-tuned ensemble.
-- Verification is done on the outer (36-km) grid for the CSU WRF runs, shown on this page.
-- Scores are calculated using the Meteorological Evaluation Tools software package.
