Error of 500-hPa geopotential height in the NoAraon experiment (shading; gpm) and 500-hPa geopotential height from ERA5 reanalysis (contour; contours from 5280 to 5940 by 60 gpm) at forecast length of a 120 h, b 144 h, c 168 h, and d 192 h. Difference between the CTL and NoAraon experiments (CTL minus NoAraon) for 500-hPa geopotential height (gpm) at forecast length of e 120 h, f 144 h, g 168 h, and h 192 h. Error of 300-hPa potential vorticity in the NoAraon experiment (shading; PVU) and 300-hPa potential vorticity from ERA5 reanalysis (contour; contours from 0 to 15 by 5 PVU) at forecast length of i 120 h, j 144 h, k 168 h, and l 192 h. Difference between the CTL and NoAraon experiments (CTL minus NoAraon) for 300-hPa potential vorticity (PVU) at forecast length of m 120 h, n 144 h, o 168 h, and p 192 h. Forecasts of the CTL and NoAraon experiments from the cycle at 00 UTC 11 August 2019 and the corresponding ERA5 reanalysis data are used
