Figure 8: Composite anomalies of SST (shaded), wind (stream arrow) and OLR (contour) during DJF or Austral summer season for all extremely high-streamflow events associated with La Niña. Unit for SST is °C, for wind is m s−1, and for OLR is w/m2. Values above 95% confidence level from a two-tailed Student’s test are shown.
