FIGURE T12. Time-longitude section (5°N–5°S) of anomalous 200-hPa velocity potential (106 m2s-1) (CDAS/Reanalysis). Contour interval is 3 x 106 m2s-1. Dashed contours indicate negative anomalies. Anomalies are departures from the 1981-2010 base period pentad means. The data are smoothed temporally by using a 3-point running average.
