FIGURE T30. Pressure-longitude section
(80°W–100°E) of the mean (top) and anomalous (bottom) divergence and divergent circulation (5°N–5°S). The divergent
circulation is represented by vectors of combined pressure vertical
velocity and divergent zonal wind. Shading and contours denote
divergence. Contour interval is 1 x 10-6
s-1. Anomalies are departures from the 1981-2010 base period
monthly means.
