Fig. 7: Potential (grey contours) and associated drift (arrows) used in Eq. (1) for the generation of the first three components of the stochastic twins.

Fig. 7

For each regime, the short names are placed at the regime means. The colored ellipses correspond to isoprobability equal to one-half of the peak probability in the regime centers, as given by each regime’s Gaussian distribution according to the best fit from ERA5 z500 anomalies. NAO: North Atlantic Oscillation. AR: Atlantic Ridge. SB: Scandinavian Blocking.
