FIGURE E15. Southern Hemisphere mean
and anomalous 500-hPa geopotential height (CDAS/Reanalysis). Mean
heights are denoted by solid contours drawn at an interval of 8 dam.
Anomaly contour interval is 3 dam with values less (greater) than -3
dam (3 dam) indicated by dark (light) shading. Anomalies are
calculated as departures from the 1979-95 base period monthly means.
