a, JJA mean of the z500 of all detrended (order n = 3) positive mass-balance years minus all negative years of the study period. b, Same as a but for all years with positive mass-balance anomalies in ACN while negative in SVA minus all years with signs reversed. Areas of significance (P < 0.05) are contained within yellow dotted contours. c,d, Same as a,b, respectively, but showing the differences of wind velocity and direction at 250 hPa (jet-stream level). Analyses are based on reanalysis data (Methods). e, The mass-balance years (MAR3.11 SMB) contained in the preceding respective composites (black). Composites for each of the four categories are shown in Extended Data Figs. 8 and 9. Uncertainties in the z500 composites arising from uncertainties in the SMB reconstruction and the inferred categorization are presented in Extended Data Fig. 10.
