FIGURE T24. Mean (top) and anomalous (bottom) 200-hPa velocity potential (10⁶ m²s^-1) and divergent wind (CDAS/Reanalysis). Contour interval is 1 x 10⁶ m²s^-1. The sample vector represents a divergent wind with magnitude of 5 m s^-1. Anomalies are departures from the 1981-2010 base period monthly means.
