Figure 6
From: Interannual to decadal variability within and across the major Eastern Boundary Upwelling Systems

(a) Correlation patterns between CalCS UI without MEI signal and NOAA SSTa (top panel) and with NCEP SLPa (middle panel); (b) Correlation patterns between HCS UI without MEI signal and NOAA SSTa (top panel) and with NCEP SLPa (middle panel); (c) -CanCS UI without MEI signal and PMM index. (d) -HCS UI without MEI signal and SPMM index. R identifies significant correlation coefficients. The correlation coefficients are calculated considering the unchanged UI (e.g. HCS not -HCS). This figure was plotted using MATLAB R2017a (https://www.mathworks.com/products/new_products/release2017a.html).
