From: The impact of long-term oceanic warming on the Antarctic Oscillation in austral winter
(a) Regression map of zonally averaged zonal wind (contour, m/s) against PC1, for the period 1901–2004, in austral winter, based on the reanalysis dataset. The zonally averaged zonal wind responses (contour, m/s) to the long-term SST anomaly pattern from (b) CAM3.5 model, (c) GFDL model and (d) CCM3 model in austral winter. The responses are the difference between the idealized run and control run. The dotted areas indicate the 90% confidence levels.
