Fig 7. Sea Surface Temperatures (SST) correlation with monthly mean precipitation for the Upper Paraguay River Basin (UPRB).

Highlighted oceanic regions show the highest correlation (Pearson) for a two month lead time (i.e., SSTs leading precipitation). The oceanic regions are as follows: ATL-N–Atlantic North, ATL-SC–Atlantic South Central, ATL-S–Atlantic South, IND-S–Indian South, PAC-NE–Pacific North East, PAC-NW–Pacific North West, PAC-SAC–Pacific South American Coast, and PAC-S–Pacific South.
