FIGURE T7. Time-longitude section of mean (top) and anomalous (bottom) 850-hPa zonal wind (CDAS/Reanalysis) for 5°N–5°S. The data are smoothed temporally by using a 3-month running average. Contour interval is 2 ms-1 (top) and 1 ms-1 (bottom). Dashed contours indicate easterlies (top) and easterly anomalies (bottom). Anomalies are departures from the 1981-2010 base period monthly means.
