The Influences of the Model Configuration on the Simulation of Stratospheric Northern-Hemisphere Polar Vortex in the CMIP5 Models

Figure 5

Box plot of the rankings of the models classified into 6 pairs of groups: HT/LTOP models, with/without nonorographic wave drag, high/low vertical resolution in the stratosphere, ESM/GCM, interactive/noninteractive chemistry, and high/low horizontal resolution. In each group, the middle value is the multimodel mean, and the dot is the median value; the upper and lower values are shown for the uncertainty range of the mean, and the uppermost and lowermost bars show the maximum and minimum values.
