Differences of local dimension in 4 × CO2 and +4 K Atmospheric Model Intercomparison Project (AMIP) simulations. Differences of Δd between average local dimension dSLP for daily sea-level pressure (SLP) data (a, b) and dSST for monthly sea-surface temperature (SST) fields for the 4 × CO2 and +4 K AMIP simulations with respect to the control runs. Error bars indicate the standard deviation of the mean. Lines: means of the ensembles, indicated in the legend by angular brackets
