Ensemble and zonal mean JJA (a, c, e, g) and DJF (b, d, f, h) meridional mass stream function (1010 kg s−1) in RCP8.5 averaged over the years 2010–2030 (baseline; a, b), and anomalies in the RCP8.5 (c, d), GLENS (e, f) and GEQ (g, h) averaged over years 2075–2095, relative to the baseline. Warm colors (positive values) indicate a clockwise rotation and cold colors (negative values) indicate an anticlockwise rotation. Contours indicate the value of seasonal averaged meridional mass stream function (1010 kg s−1) in the baseline. Hatched areas are regions where changes are not statistically significant at the 5% level using the Student’s t test.
