Models are ranked by CPI scores for each variable: summer sea surface temperature, winter meridional sea-ice extent, annual sea-level pressure, summer/winter precipitable water, summer/winter 85hPa air temperature, and summer 85hPa air temperature. Markers are for seasonal CPI scores and solid black line is for combined CPI scores. Blue lines are upper and lower bounds for the combined score taking into account multi-decadal variabilities of seasonal components. The grey crown width is the combination of 9th percentiles of CMIP5 GCMs multi-decal variabilities. Models with obvious similarities in code or produced by the same institution are marked with the same color (clusters), following Knutti et al. (2). 2

Here we compare annual geopotential heights at 5hPa (zg5[ann], left) and at 25hPa (zg25[ann], right) without masking ice-sheet areas to annual sea-level pressure over the ocean (psl[ann], X-axis).

The field of reference is for the period 98-2. Thin light blue lines are for the 4 CMIP5 GCMs (historical+rcp85) and thick dark grey lines are for the reanalyses. Three GCMs are highlighted with thick colored lines: in purple, in dashed red and in solid red. Each point of a line is the central year of the -year period.
