Horizontal distributions of difference in absolute error of 500-hPa geopotential height (gpm) between the CTL and NoAraon experiments (CTL minus NoAraon) for forecast length of a 0 h, b 48 h, c 96 h, d 144 h, e 192 h, and f 240 h. Errors are calculated against ERA5 reanalysis, and differences in absolute error are averaged over all cycles from the years 2018 and 2019. Statistical significance for the difference at 90% confidence level is denoted by black dots
