Dependency of the simulated NICAM climatology on the vertical resolution. Dependency on the vertical resolution of the (upper) zonal mean temperature (K), and (lower) zonal mean zonal wind (m s-1). From left to right: JRA25 reanalysis (Onogi et al. ), CIRA86 (http://badc.nerc.ac.uk/view/badc.nerc.ac.uk__ATOM__dataent_CIRA), NICAM (Δzmax = 2 km), NICAM (Δzmax = 1 km), and NICAM (Δzmax = 0.5 km). For CIRA86, the climatology for June is shown. All the other panels are the averages for June 2004. Shading denotes deviations from the CIRA86 climatology.
