CNRM 20thc run 1: No stadium-wave signature. (a) Two plots are given. The first is the M-SSA spectrum for this model. It shows leading modes 1&2 to be outside the red-noise envelope. Their error bars overlap; yet there is no separation from the remaining modes. The second plot in (a) shows the cumulative variance accounted for by the first twenty modes. (b) Shows RCs of the individual modes. RCs for modes one and two are high-frequency modes. RCs for mode three are decadal-plus, but no propagation.
