Fig. 7: Relation between the skin temperature difference between the subtropical North Atlantic (subTNA) and the Labrador Sea verus the NAO’s standard deviation.

From: Winter heavy precipitation events over Northern Europe modulated by a weaker NAO variability by the end of the 21st century

Fig. 7

Two-dimensional histogram of the skin temperature difference between the subtropical North Atlantic (subTNA) and the Labrador area versus the NAO’s standard deviation for the a 1970–2014 period, the 2050–2099 period for b the ssp1–2.6 ensemble and c the SSP5–8.5 ensemble. Colour bar shows the percentage of models within a bin. The linear regression of both variables is shown for the three subplots. The slope of the linear regression is shown in every subplot, and it is marked with an asterisk when the linear regression is significantly different from zero (p < 0.05). ERA5 is shown with a green scatter point in the historical (a) subplot. The subTNA is calculated as the area average between the latitudes 30°N and 44°N and longitudes 80°W and 38°W. The Labrador Sea area was calculated as the area average of the skin temperature within latitudes 50°W and 77°W and longitudes 83°W and 30°W. Land points were masked out.
