(a) Regression map of 500-hPa geopotential height (contour, m) against PC1, for the period 1901–2004, in austral winter based on the reanalysis dataset. 500-hPa geopotential height responses (contour, m) 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 light, medium, and dark shading indicates the 90%, 95% and 99% confidence levels (positive, yellow; negative, green), respectively. The map was generated by The NCAR Command Language (Version 6.3.0) [Software]. (2016). Boulder, Colorado: UCAR/UCAR/CISL/TDD. http://dx.doi.org/10.5065/D6WD3XH5.
