…om 2 to 4 This commit changes the default value of the atmosphere core namelist option config_number_of_sub_steps from 2 to 4 in the Registry.xml file. This change addresses an issue in convection-permitting simulations where noise can sometimes appear in the jet streams using the previous default value (config_number_of_sub_steps = 2). The noise, when present, also produces unphysical features in horizontal kinetic energy spectra at high wavenumbers.
