Pentad 200-hPa Velocity Potential Anomalies


FIGURE T12.  Time-longitude section of anomalous 200-hPa velocity potential averaged between 5N-5S (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 using a 3-point running average.
