Convergence of Extreme Value Statistics in a Two-Layer Quasi-Geostrophic Atmospheric Model

Figure 1

Statistical properties of the total energy for K. (a) Integrated autocorrelation time scales: zonal average of (dashed line with star markers), (dotted line with circle markers), (continuous line); histograms of the (b) local, (c) zonally averaged, and (d) average mid-latitude observables. In the case of (b)–(d), the continuous lines show the approximation of the PDFs by kernel smoothing (ksdensity function in MATLAB); the colours mark different latitudes according to the legend.
