Fig. 2: The atmospheric circulation anomalies associated with CPAC convection compared to Larsen C surface melt.

The DJFM detrended correlation (shaded), 1991–2015, of (left; (a, c, e) Larsen C surface melt and (right; (b, d, f) CPAC OLR with a, b 250 hPa streamfunction, c, d 500 hPa geopotential height, and e, f vertically integrated moisture flux divergence. Correlations significant at p < 0.10 are denoted by bold black contours. CPAC OLR correlations are multiplied by −1 to reflect anomalies associated with enhanced CPAC convection. Dashed black arrows in a, b schematically show the path of Rossby wave propagation. Solid black arrows in c, d schematically show anomalous winds across the AP associated with the Drake Passage anticyclonic circulation anomaly.
