Event synchronization CN for extreme rainfall over South America. (a) Network divergence, $\Delta S$, is defined as the difference of in-strength and out-strength at each node (see Eq. (123)). The boxes labeled 1 to 7 are used for the tracking of extreme events. (b) Strength out of SESA, $S_i^{\text{out}}\left(SESA\right)$, which is the average out-Strength restricted to SESA ((see Eq. (124))). (c) Strength in of SESA, $S_i^{\text{in}}\left(SESA\right)$, which is the average in-Strength restricted to SESA ((see Eq. (125))). (d) Temporal evolution of extreme rainfall events from SESA to ECA along the sequence of boxes indicated in (a).
