SOI, Tahiti and Darwin SLP and OLR Anomalies

NOVEMBER 2024

FIGURE T1.  Five-month running mean of the Southern Oscillation Index (SOI) (top), sea-level pressure anomaly (hPa) at Darwin and Tahiti (middle), and outgoing longwave radiation anomaly (OLR) averaged over the area 5N-5S, 160E-160W (bottom). Anomalies in the top and middle panels are departures from the 1991-2020 base period means and are normalized by the mean annual standard deviation. Anomalies in the bottom panel are departures from the 1991-2020 base period means. Individual monthly values are indicated by "x"s in the top and bottom panels. The x-axis labels are centered on July.
