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 indicated by shading. Anomalies are calculated as departures from the 1991-2020 base period monthly means.
