SON correlations over 1979–2014 of McMurdo temperature with (a) NOAA’s ERSSTv4 tropical SST, (b) Southern Hemisphere ERA-Interim 500 hPa geopotential height, and (c) western West Antarctic ERA-Interim 2 m temperature. Shading indicates where correlations are statistically significant and is drawn as in Fig. 2. Contour interval is 0.2.
