Percentage differences in RMSE (%) between the CTL and NoAraon experiments (CTL minus NoAraon) for the year a 2017, b 2018, c 2019, and d 2021. RMSEs of geopotential height are calculated over areas north of 70°N using ERA5 reanalysis as a reference, and RMSEs from all cycles of the corresponding year are averaged. Statistical significance (denoted by yellow dots) for the difference is computed using a bootstrap resampling method and its confidence level is 90%
