Figure 3

Composites of (a) RH, (b) WSH, (c) VOR, (d) Z 26 , (e) MPI and (f) ICI for +PDO and −PDO from 1992 to 2013. Since +PDO is from 1992~2005, while −PDO is from 2005~2013, each pair of plots approximately describes the decadal change between the two epochs. Stipples indicate regions where the composite mean is significant. Dashed box in northern SCS shows the main area of interest. In each panel abscissa is longitude and ordinate is latitude. Maps plotted using MATLAB Version#R2012a (7.14.0.739) 64-bit (glnxa64) (https://www.mathworks.com/support/sysreq/previous_releases.html).
