Fig. 3: Maps of predictability in the Atlantic region.
From: NAO predictability from external forcing in the late 20th century

We map ACC values for a sea-level pressure, b SST, and c precipitation. We display only the raw ensemble mean. We only color those pixels with ACC values that are statistically significant at the 95% level. In panel b, highlight the location of the warming hole by contouring the −1 °C/54-year trend in SST in observations (black) and our ensemble (gray). In panel c, we highlight the location used to calculate Northern European precipitation reported in the text.
