Fig. 2: Lagged association of Northern Hemisphere T2m and sea ice with SAM.
From: Link of the Warm Arctic Cold Eurasian pattern to the Southern Annular Mode variability
a Lagged regressions of T2m in the Northern Hemisphere with respect to the SAM index when SAM leads by 1, 3, 5 and 7 pentads. b Lagged regressions of sea ice concentration in the North Atlantic–Arctic sector with respect to the SAM index. The magnitude corresponds to one standard deviation of the SAM index. The unit is °C for (a) and % for (b). Stippling indicates that the regression is significant at the 95% confidence level based on a bootstrapping resampling method.
