FIGURE E14. Southern Hemisphere mean
and anomalous sea level pressure(CDAS/Reanalysis). Mean values are
denoted by solid contours drawn at an interval of 4 hPa. Anomaly
contour interval is 2 hPa with values less (greater) than -2 hPa (2
hPa) indicated by dark (light) shading. Anomalies are calculated as
departures from the 1981-2010 base period monthly means.
