FIGURE T3. Five-month running mean and individual monthly mean ("x"s) of the 200-hPa zonal wind anomaly index averaged over the area 5N5S, 165W110W (top), the 500-hPa virtual temperature anomalies averaged over the latitude band 20N20S (middle), and the equatorial zonally-averaged zonal wind anomalies at 30-hPa ("x"s) and 50-hPa ("o"s) (bottom). In the top panel, anomalies are normalized by the mean annual standard deviation. Anomalies are departures from the 197995 base period means. The x-axis labels are centered on July.
