Figure describing the 150-day periodicity of the Southern Annular Mode (SAM) (IMAGE)
Caption
Panels showing lagged composited differences for (b-d) anomalous total precipitation, (f-h) zonal wind stress, and (j-l) meridional wind stress for the Southern Hemisphere below the 20th parallel. Composites were computed by first averaging the anomalies at lags of 0, -75, or +75 days with respect to dates local maxima or minima reached, and then calculating the difference (maxima minus minima) for each lag.
