FIGURE T19. Mean (top) and anomalous (bottom) sea level pressure (SLP) (CDAS/Reanalysis). SLP contour interval is 2 hPa, and 1000 hPa has been subtracted from contour labels. SLP values below 1000 hPa are indicated by dashed contours. Anomaly contour interval is 1 hPa and negative anomalies are indicated by dashed contours. Anomalies are departures from the 1981-2010 base period monthly means.
