Figure 2: Agulhas leakage and SST are highly linked around South Africa.
From: Atlantic multi-decadal oscillation covaries with Agulhas leakage

Correlation between annual Agulhas leakage and NST for the forced-ocean models (a) INALT01, (b) OFES and (c) SST for the coupled climate model CM2.6 (regions hashed in grey denote significance below the 99% level). (d) Annual Agulhas leakage time series (dashed lines show linear trends, with INALT01 (OFES) significant at the 99% (95%) level and CM2.6 not being significant). Rectangles in a–c show regions where NST and SST are averaged.
