Figure 5: Map of linear correlation coefficients between an index of
the Niño 1+2 SST anomalies (ENI) and the absolute value of the
vertical shear between 700 and 200 mb for 1968-92. Magnitudes are
multiplied by 100; contour interval is 0.10. Negative contours are
dashed. Regions where the correlations are significant at the 95%
level are shaded.
